Lukáš Fryč created RF-12730:
-------------------------------
Summary: Render and Oncomplete attributes are not evaluated if
command is in conditionally rendered subtree
Key: RF-12730
URL: https://issues.jboss.org/browse/RF-12730
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: component-a4j-core, core
Affects Versions: 4.2.0.Final
Environment: MyFaces 2.1.6 / Mojarra 2.1.7
Tomcat 6.0.35 / 7.0.26
Reporter: Michael Heinen
Assignee: Lukáš Fryč
Fix For: 4.3.0.M3
Attachments: onc333.war, onc42.war, RF-12145.zip, zOnc333WithLibs.war,
zOnc42New.war, zOnc42WithLibs.war
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.
