public class RichTrain

extends org.apache.myfaces.trinidad.component.UIXProcess

implements javax.faces.component.NamingContainer

The train component presents a user with a series of stops, each stop representing a step in a multi-step process. The train walks the user through these steps, in a suggested order (the order being dictated by the underlying model). Each step is rendered as a train stop consisting of an image and a textual link indicating if they are in visited, current, unvisited and disabled states. Train can also be rendered in a vertical layout - the default being a horizontal layout. Trains are not rendered on printable pages.

Model

The train takes a model of type org.apache.myfaces.adf.model.MenuModel that in turn extends a TreeModel. The last node along the focus path and its siblings are rendered as train stops. The default MenuModel implementation knows how to go from the current viewId to the focusRowKey. Notice that the MenuModel has no special knowledge of page navigation and places no requirements on the nodes that go into the tree. The last node along with it's sibling, in the tree are stamped out using the "nodeStamp" facet, which should contain a commandNavigationItem component. This allows the default actionListener mechanism to be used for page navigation.

Behavior

The train behavior (how the train takes the user through it's steps in a multi-step process) is dictated by the model implementation. Product teams are encouraged to implement custom behavior to suit their needs. The following behaviors allow the user to walk through a series of steps in a sequential order, but they exhibit slightly different behaviors.

• "Plus One" - From the current stop the user can navigate to any previous visited stops and the next enabled stop (in unvisited state). The remaining stops appear disabled.
  So, if the user is on the 5th step of a process and goes back to step 2, then the user can only navigate to step 1 (which appears as a visited stop) and step 3 (appears as an unvisited stop). Steps 4 and 5 cannot be reached (and the corresponding stops appear disabled).
• "Max Visited" - From the current stop the user can navigate to any previous stops and the next enabled stop (or upto the max visited stop). If the current stop happens to be the max visited stop then the next stop is enabled (and in unvisited state). The remaining stops appear disabled.
  So, if the user is on the 5th step of a process and goes back to step 2, then the user can navigate from step 2 to steps 1, 2, 3, 4, and 5, as they all have been visited (except for the current stop they all appear in visited state). Now if the user in on step 5, step 6 will be enabled (and the stop appears in unvisited state).

The class org.apache.myfaces.adf.model.ProcessMenuModel and org.apache.myfaces.adf.model.ProcessUtils were created to support the "Plus One" and "Max Visited" scenarios. Please see the javadoc for these classes for more information.

Sub-Process

A multi-step process may be launched from within another multi-step process, or a multi-step process may be nested inside another process as one of its steps. When the user navigates to a step in a sub-process, the parent train is represented as an icon appended before and after the sub-train, to indicate that the sub-train is a sub-process.

Simplified train tag usage

The tag usage for the train component has been simplified. This tag can be used in its simpler form as below:
<af:train value="#{my_bean.menuModel}"/>

• The benefits of using the simpler tag are:
  • Simpler and smaller jspx pages. There is no need to specify the nodestamp facet (that includes a commandNavigationItem) in every page that contains a train component.
  • This means that the commandNavigationItem component (that is used to stamp out the train stops) is now created implicitly. Also the EL expressions are bound to the relevant properties of the component automatically.
  • The properties of commandNavigationItem that are EL bound automatically are - action, disabled, immediate, messageType, shortDesc, showRequired, textAndAccessKey and visited.
  • The only requirement for using the simplified train tag is that customers need to ensure that the object that represents the model for a train stop, resemble (contain the same methods as) oracle.adf.view.rich.model.TrainStopModel . IOW, the object returned from the call to CollectionModel.getRowData(int) should be an object resembling TrainStopModel or be a subclass of TrainStopModel.
  • NOTE: Customers can still use the full-blown tag usage, depending on their specific use cases.

Events:

Type	Phases	Description
org.apache.myfaces.trinidad.event.AttributeChangeEvent	Invoke Application Apply Request Values	Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.

Method Detail

getInlineStyle

public final java.lang.String getInlineStyle()

Gets the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.

Returns:

the new inlineStyle value

setInlineStyle

public final void setInlineStyle(java.lang.String inlineStyle)

Sets the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.

Parameters:

inlineStyle - the new inlineStyle value

getStyleClass

public final java.lang.String getStyleClass()

Gets a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.

Returns:

the new styleClass value

setStyleClass

public final void setStyleClass(java.lang.String styleClass)

Sets a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.

Parameters:

styleClass - the new styleClass value

getShortDesc

public final java.lang.String getShortDesc()

Gets the short description of the component. This text is commonly used by user agents to display tooltip help text, in which case the behavior for the tooltip is controlled by the user agent, e.g. Firefox 2 truncates long tooltips. For form components, the shortDesc is displayed in a note window. For components that support the helpTopicId attribute it is recommended that helpTopicId is used as it is more flexible and is more accessibility-compliant.

Returns:

the new shortDesc value

setShortDesc

public final void setShortDesc(java.lang.String shortDesc)

Sets the short description of the component. This text is commonly used by user agents to display tooltip help text, in which case the behavior for the tooltip is controlled by the user agent, e.g. Firefox 2 truncates long tooltips. For form components, the shortDesc is displayed in a note window. For components that support the helpTopicId attribute it is recommended that helpTopicId is used as it is more flexible and is more accessibility-compliant.

Parameters:

shortDesc - the new shortDesc value

getUnsecure

public final java.util.Set<java.lang.String> getUnsecure()

Gets A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute.

Returns:

the new unsecure value

setUnsecure

public final void setUnsecure(java.util.Set<java.lang.String> unsecure)

Sets A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute.

Parameters:

unsecure - the new unsecure value

isVisible

public final boolean isVisible()

Gets the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.

Returns:

the new visible value

setVisible

public final void setVisible(boolean visible)

Sets the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.

Parameters:

visible - the new visible value

getCustomizationId

@Deprecated
public final java.lang.String getCustomizationId()

Deprecated. This attribute is deprecated. This attribute will be removed in the next release. Use the 'id' attribute instead.

Gets This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.

Returns:

the new customizationId value

setCustomizationId

@Deprecated
public final void setCustomizationId(java.lang.String customizationId)

Deprecated. This attribute is deprecated. This attribute will be removed in the next release. Use the 'id' attribute instead.

Sets This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.

Parameters:

customizationId - the new customizationId value

isClientComponent

public final boolean isClientComponent()

Gets whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.

Returns:

the new clientComponent value

setClientComponent

public final void setClientComponent(boolean clientComponent)

Sets whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.

Parameters:

clientComponent - the new clientComponent value

getClientAttributes

public final java.util.Set getClientAttributes()

Gets a set of client attribute names.

Returns:

the new clientAttributes value

setClientAttributes

public final void setClientAttributes(java.util.Set clientAttributes)

Sets a set of client attribute names.

Parameters:

clientAttributes - the new clientAttributes value

getPartialTriggers

public final java.lang.String[] getPartialTriggers()

Gets the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.

Returns:

the new partialTriggers value

setPartialTriggers

public final void setPartialTriggers(java.lang.String[] partialTriggers)

Sets the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.

Parameters:
