RichDynamicDeclarativeComponent

public class UIXDynamicDeclarativeComponent

extends UIXInclude

implements javax.faces.component.NamingContainer

Defines a dynamic declarative component without a need for a specific tag. Dynamic declarative components allow the UI definition of a component to be defined in terms of a composition of other components and then treated as a single component.

You can pass attributes using JSP tag attributes, or by using <f:attribute>. Facets can also be set as normal using <f:facet> tags. The definition can refer to the attributes of the component by using the "var" EL variable and the component itself using the "componentVar" EL variable that are setup on the <af:componentDef> tag. The definition can reference a facet using the <af:facetRef> tag. Each facet can only be referenced once.

If you put a component as a child of a declarative component but fail to put it inside of a facet and fail to reference that facet in the component definition file (via facetRef), that component will not be rendered.

Dynamic declarative components support flattened chlidren. This means that children of the declarative component can be seen by the declarative component parent. So for example, input components at the root level of the declarative component will be correctly rendered if the declarative component resides in a panelFormLayout component.

Note about stretching layouts and flowing/scrolling layouts:

With today's web browsers, it is not reliable to have vertically-stretched content inside of areas that also have scroll bars. If you want the outer areas of your page structure to stretch, you need to be careful of how you assemble your component tree.

• First, build up a structure of stretchable components (using panelSplitters and panelStretchLayouts).
• Second, inside of this structure, create islands of non-stretched content. These islands should be rooted with panelGroupLayouts with layout="scroll". This is an ideal component because it can be stretched and does not stretch its children--which likely don't support being stretched anyway.

Rules of thumb:

1. Never place a scrolling panelGroupLayout inside of another scrolling panelGroupLayout since users do not like nested scroll bars.
2. Never specify percentage heights in any component's inlineStyle attribute.
3. Never use the "position" style in any component's inlineStyle attribute.
4. Unless you are using fixed pixel heights on them, you would never place a panelSplitter or panelStretchLayout inside of any panelGroupLayout regardless of what you have set its layout attribute to.

If you believe that you need to break one of these rules, this is an indication that your page structure is not following the page structure guidelines and you will likely have troubles getting your application to render consistently across various web browsers and computing platforms.

• For specific details of about component stretching, please see the "geometry management" section in the tag documentation of each component.
• See the demo application for real world layout examples that you can use as a starting point in your application. A good starting point is the "Layout Basics" page listed under the "Framework Features" tab of the demo application.

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.

Constructor Detail

UIXDynamicDeclarativeComponent

public UIXDynamicDeclarativeComponent()

Construct an instance of the UIXDynamicDeclarativeComponent.

UIXDynamicDeclarativeComponent

protected UIXDynamicDeclarativeComponent(java.lang.String rendererType)

Construct an instance of the UIXDynamicDeclarativeComponent.

Method Detail

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

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

getFamily

public java.lang.String getFamily()

Overrides:

getFamily in class UIXInclude

getBeanType

protected org.apache.myfaces.trinidad.bean.FacesBean.Type getBeanType()

Overrides:

getBeanType in class UIXInclude
