commandLink does not work in dataList
-------------------------------------
Key: MYFACES-213
URL: http://issues.apache.org/jira/browse/MYFACES-213
Project: MyFaces
Type: Bug
Versions: 1.0.9 beta
Environment: Tomcat 5.0, Win2k, JDK 1.4.2_06
Reporter: Brandon Goodin
Priority: Critical
I've been trying to get a simple commandLink to work in a dataList. I have the
dataList bound to a UIData component (binding="#{categoryAdmin.ancestorTree}")
on the backing bean. It properly displays links. However, when i select the
link it fails to call the appropriate action method
(action="#{categoryAdmin.ancestor}")and returns back to the page. No error
meassages are written to the screen or logs.
Things i have tried with no success are:
- placing my backing bean in session rather than request
- placed <h:messages/> on the jsp to see any error messages (none appear)
- Debugged the phases in the LifeCycleImpl. It hits all the full LifeCycle
phases
(restoreView,applyRequestValues,processValidations,updateModelValues,invokeApplication).
However, i am not able to determine what is really happening in these phases
to result in the outcome.
- used h:commandLink and x:commandLink (both with session and request backing
bean)
- set a breakpoint in my action method (public String ancestor(){...}) method
and it never gets called.
Following is my page code. I provided the whole page to give context in case
there are other conflicts that may be taking place. I'd be happy to provide a
small app to reproduce this if my explanation is not enough.
