|Oracle Fusion Middleware Tag Reference for Oracle ADF Faces
11g Release 1 (188.8.131.52.0)
UIComponent class: oracle.adf.view.rich.component.rich.layout.RichShowDetailHeader
Component type: oracle.adf.RichShowDetailHeader
The showDetailHeader provides a means of toggling the contents under a header between being disclosed(shown) or undisclosed(hidden).
On mobile devices the showDetailHeader renders nothing itself, but does render its children.
If the "disclosed" property on the showDetailHeader is set to false, the icon arrow will point sideways, and the children of the showDetailHeader will not be rendered. If the "disclosed" property of the showDetailHeader is set to true, the icon arrow will point down and the children of the showDetailHeader will be rendered.
Clicking on the icon of the showDetailHeader will deliver a
DisclosureEvent to the server.
disclosedTransient attribute is not supported by the rich client renderers and may only be used with the Apache MyFaces Trinidad RenderKit. If this attribute is set to true in an ADF page, the component will not function correctly. This attribute appears in ADF due to it being inherited from
UIXShowDetail. The value must either not be set, or must be set to false, a value of true will cause problems.

|org.apache.myfaces.trinidad.event.DisclosureEvent||Apply Request Values,
|The disclosure event is delivered when a node is disclosed.|
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.|
|context||A Facet that can be used to display contextual information on the header. The contextual information is displayed next to the header text|
|help||This facet is deprecated, helpTopicId should be used for providing help. Both help facet when rendered inline and helpTopicId with instructions text are rendered in the same spot, so if helpTopicId is specified and it has instructions text, the help facet will not be rendered if specified inline. Help content that is displayed to the user. The content of the help is displayed inline inside the header content or as a popup through a link. The attribute helpType controls whether the help is displayed inline or in a popup.|
|info||A facet that displays addition information inside the header content. This informtion is displayed end aligned under the header|
|legend||A Facet that can be used to display legend information on the header. If the help facet has a child and it is visible, the contents of the legend facet will be rendered beneath the task stamps. If the legend facet is not visible or no children exist, then it gets rendered below the title.|
|menuBar||MenuBar component that is rendered on the header.|
|toolbar||Toolbar component that is rendered on the header.|
|attributeChangeListener||javax.el.MethodExpression||Only EL||a method reference to an attribute change listener. 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.|
|binding||oracle.adf.view.rich.component.rich.layout.RichShowDetailHeader||Only EL||an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.|
|contentStyle||String||Yes||the inline style of the content region.|
|customizationId||String||Yes||This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.|
|disclosed||boolean||Yes||whether or not to disclose the children|
|disclosedTransient||boolean||Yes||stops the local value of disclosed from being set by renderers. This allows the value to always be taken from the value of the disclosed value expression. Disclosed values must be updated in other ways (i.e. from a disclosure listener)|
|disclosureListener||javax.el.MethodExpression||Only EL||a method reference to a disclosure listener|
|dontPersist||String||Yes||a list of attributes whose changes are NOT to be persisted by FilteredPersistenceChangeManager via the "Persistent Change Manager" registered in adf-config.xml. The token 'ALL' can be used in the list here to indicate that all attribute changes that the component implicitly persists should be excluded. If there is a conflict of values, "dontPersist" always precedes "persist".|
|headerLevel||int||Yes||allows the default HTML header level assignment (H1 through H6) of the header to be overridden.
Header components are assigned HTML header level assignements of H1 through H6. (Similar to size) the header level assigned is determined based on containment within other header components. For example, a header that is not contained by another header component will automatically render as an H1 header level. A child header contained inside this header would automatically render as an H2 header level. While the display of header components is determined by the size skinning selector assigned, HTML header level is important for correct page structure, especially when used with screen reader applications.
The headerLevel attribute by default is -1, where the HTML header level is then calculated by containment as defined above. This is the preferred setting - it is recommended that you design your page nesting header components to take advantage of the automatically assigned header levels. Alternately, setting the headerLevel attribute to values 1 through 6 will force the corresponding HTML header level to render as part of the header component, regardless of its containment with other header components on the page.
Plesae be careful if overriding the header level! The HTML header level assignments (H1 through H6) controlled by this attribute are relied upon by screen reader applications to appropriately identify the underlying structure of the page. Make sure your use of header components and assignment of header levels make sense for your page. When using an override value, consider the effects of having headers inside disclosable sections of the page.
|helpTopicId||String||Yes||the id used to look up a topic in a helpProvider.|
|helpType||String||Yes||Valid Values: inline, link
Along with the help facet this is deprecated, helpTopicId should be used for providing help. Controls if the help is displayed inline or as a link to a popup.
|icon||String||Yes||the URI of an image to be displayed in the header. This attribute supports these various types of URIs:
|id||String||No||the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
|immediate||boolean||Yes||whether data validation - client-side or server-side - should be skipped when events are generated by this component. When immediate is false (the default), the disclosure event will be delivered during the Invoke Application phase, which will trigger validation. When set to true, the disclosure event will be executed during the Apply Request Values phase.|
|inlineStyle||String||Yes||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.|
|messageType||String||Yes||Valid Values: info, confirmation, warning, none, error
whether an error, info, confirmation, or warning header is needed.
|partialTriggers||String||Yes||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.|
|persist||String||Yes||a list of attributes whose changes are to be persisted by FilteredPersistenceChangeManager via the "Persistent Change Manager" registered in adf-config.xml. The token 'ALL' can be used in the list here to indicate that all attribute changes that the component implicitly persists should be included.|
|rendered||boolean||Yes||whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.|
|shortDesc||String||Yes||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.|
|size||int||Yes||allows the default skinning size of the header to be overridden.
Sizes for skinning start at size 0 (the largest) and progress to size 5 (the smallest). The size is determined based on containment within other header components, and is accomplished via the assignement of skinning keys. For example, a header that is not contained by another header component will automatically be displayed as size 0. A child header contained inside this header would automatically be displayed as size 1.
The size attribute by default is -1, where the size is then calculated by containment as defined above. This is the preferred setting - it is recommended that you design your page nesting header components to take advantage of the automatically assigned sizes. Alternately, setting the size attribute to values 0 through 5 will force that size skinning value assignment on the header component, regardless of its containment with other header components on the page.
Please note that while header components support a total of six levels of skinning diferentiation, less than this may be defined in your skin. Also, setting the header size to something greater then the supported value will style the header the same as the largest supported value. Please see the Skinning Selectors documentation for the assigned skinning keys used by the component.
|styleClass||String||Yes||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'.|
|text||String||Yes||the label of the header.|
|type||String||Yes||Valid Values: default, flow, stretch
how the component will handle geometry management. Options are:
|unsecure||java.util.Set||Yes||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.|
|visible||boolean||Yes||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.
Not supported on the following renderkits: org.apache.myfaces.trinidad.core
