Lukáš Fryč updated RF-12730:
----------------------------
Affects Version/s: 4.3.0.CR1
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, 4.3.0.CR1
Environment: MyFaces 2.1.6 / Mojarra 2.1.7
Tomcat 6.0.35 / 7.0.26
Reporter: Michael Heinen
Attachments: onc333.war, onc42.war, RF-12145.zip, zOnc333WithLibs.war,
zOnc42New.war, zOnc42WithLibs.war
Original Estimate: 3 hours
Remaining Estimate: 3 hours
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.
