Summary

Tag Name: <trh:body>
Java Class: org.apache.myfaces.trinidad.component.html.HtmlBody
Component Type: org.apache.myfaces.trinidad.HtmlBody
Required Ancestor Tag(s): trh:html

Tag for the HTML body element. In addition to providing support for the standard HTML body functionality, the Trinidad body component enables partial-page rendering (PPR) support and assigning initial page focus.

The body component resets the Trinidad EL context when code re-enters the component via an invoke on component call or a visit tree call. See the org.apache.myfaces.trinidad.context.ComponentContextManager for more information.

Code Example(s)

<trh:html>
  <trh:body>
    <trh:outputText value="Here is some text inside a body element"/>
  </trh:body>
</trh:html>

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 event might include the width of a column that supported client-side resizing.

Attributes

Name Type Supports EL? Description
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 org.apache.myfaces.trinidad.component.html.HtmlBody 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.
firstClickPassed boolean Yes Default Value: false

whether or not Trinidad will allow the first click to go through in certain instances. When a PPR event occurs, we block all subsequent user input until it completes. However, there may be instances where the client wants to receive the very first click. For example, if the user entered text in an inputText that fires a PPR request, then the user immediately clicked a submit button two events will be triggered - an onchange followed by an onclick. The onchange will trigger the client action which will immediately start the PPR blocking, so the onclick will get consumed by the blocking code and no submit will occur. Setting this value to true will allow the click to go through.
Not supported on the following agents: pda
id String No the identifier for the component. Every component may be named by a component identifier that must conform to the following rules:
  • They must start with a letter (as defined by the Character.isLetter() method) or underscore ( _ ).
  • Subsequent characters must be letters (as defined by the Character.isLetter() method), digits as defined by the Character.isDigit() method, dashes ( - ), or underscores ( _ ). To minimize the size of responses generated by JavaServer Faces, it is recommended that component identifiers be as short as possible. If a component has been given an identifier, it must be unique in the namespace of the closest ancestor to that component that is a NamingContainer (if any).
initialFocusId String Yes the id of the component to which you want the focus to be when the full page renders. The accessibility-mode must be set to "inaccessible" for this feature to be on.
Not supported on the following agents: pda
inlineStyle String Yes the inline CSS style for this element
onclick String Yes an onclick Javascript handler.
ondblclick String Yes an ondblclick Javascript handler.
onkeydown String Yes an onkeydown Javascript handler.
onkeypress String Yes an onkeypress Javascript handler.
onkeyup String Yes an onkeyup Javascript handler.
onload String Yes an onload Javascript handler.
onmousedown String Yes an onmousedown Javascript handler.
onmousemove String Yes an onmousemove Javascript handler.
onmouseout String Yes an onmouseout Javascript handler.
onmouseover String Yes an onmouseover Javascript handler.
onmouseup String Yes an onmouseup Javascript handler.
onunload String Yes an onunload Javascript handler.
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.
rendered boolean Yes Default Value: true

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 bean. This text is commonly used by user agents to display tooltip help text.
styleClass String Yes the CSS style class of the bean.
