[richfaces-issues] [JBoss JIRA] (RF-13739) Placeholder in collapsibleSubTable template

[Michal Petrov (JIRA)]

    [ https://issues.jboss.org/browse/RF-13739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12988531#comment-12988531 ] 

Michal Petrov commented on RF-13739:
------------------------------------

[~bleathem], the placeholder is supposed to apply to its parent (parent's clientId) if the selector is empty. In this case the element with that id doesn't exist because the panelGroup doesn't render any HTML (which is WAI as far as JSF is concerned).

The other issue (element being rendered twice) was prevented by overriding {{RendererBase.encodeEnd}}. However in 4.5 encodeEnd is final and calling doEncodeEnd goes to PlaceholderRenderer; we would need PlaceholderRendererBase to be visited at some point.

> Placeholder selector set to empty string ({{selector=""}}) does not  work when nested inside richCollapsibleSubTable template. The expected result is that all inputs will contains the placeholder text, however none of them does. If you set selector to a specific ID, the test succeeds.
> This only happens when you attach the placeholder to {{<textarea>}} or {{<input>}}.
> For both cases we have facelets and tests in Metamer and [Jenkins job|https://jenkins.mw.lab.eng.bos.redhat.com/hudson/view/RichFaces/view/4.5/job/richfaces-4.5-metamer-ftest--server-compatibility--misc/] which runs the tests.
