[richfaces-issues] [JBoss JIRA] (RF-12145) RF4.2: Render and Oncomplete attributes not evaluated after invokeApplication if command is not rendered anymore

[Lukáš Fryč (JIRA)]

    [ https://issues.jboss.org/browse/RF-12145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745354#comment-12745354 ] 

Lukáš Fryč commented on RF-12145:
---------------------------------

[~mhn], if you will find that your case does not actually work as I suggested,

feel free to reopen the issue.

It would really help if you will minimize the sample to absolutely minimum.

The example might be the facelet code from integration test mentioned above: no model dependencies, just RichFaces components.

> Sample use case:
> The last page of a wizard contains a commandButton with an EL expressions in the oncomplete attribute and in the render attribute.
> This button renders an outer component in order to close the wizard. The button itself is not rendered anymore after clicking it.
> As a consequence the EL expressions of the oncomplete attribute and of the render attribute is not evaluated after the invocation of an actionListener.
> This worked well with richfaces 3.3.3, therefore it's a critical regression.
> I'll attach a sample webApp for richfaces 4.2 and for riochfaces 3.3.3
> Note that the render attribute of f:ajax is evaluated correctly.
> These attributes of the clicked command must be evaluated in phase render response in all cases.
