Howard Abrams updated MYFACES-833:
----------------------------------
Fix Version: 1.1.3
> HtmlFormRendererBase saves form state before components have been rendered -
> breaks auto id generation
> ------------------------------------------------------------------------------------------------------
>
> Key: MYFACES-833
> URL: http://issues.apache.org/jira/browse/MYFACES-833
> Project: MyFaces
> Type: Bug
> Components: Implementation
> Versions: 1.1.0
> Environment: Sun JDK 1.5
> Windows XP
> Facelets 1.0d/1.0e
> Tomcat 5.x
> Reporter: Max Muermann
> Fix For: 1.1.3
> Attachments: HtmlFormRendererBase.java.diff
>
> In HtmlFormRendererBase, the following code is executed in the encodeBegin()
> method:
> //write state marker at the beginning of the form
> ViewHandler viewHandler = facesContext.getApplication().getViewHandler();
> viewHandler.writeState(facesContext);
> This causes problems (especially when using facelets), as some components
> first call getClientId() - which causes a new id for the component to be
> generated by the ViewRoot - in their own encodeBegin() method.
> If this is the case, as the form encodeBegin() is called before any of its
> child components are rendered, those components that do not yet have an id
> assigned save their state with a null id. When the view state is restored in
> the next request, these ids will be regenerated, starting with _id0. However,
> if there are other components in the page that also require autogenerated
> ids, some ids will be duplicated and the "problem" components will receive
> different ids to when they were first rendered.
> Attached is a patch to HtmlFormRendererBase which moves the state saving
> operation of the form to the encodeEnd() method, where all child components
> will have been rendered and therefore will have called getClientId() at least
> once.
