-------------------------------------
Resolution: Duplicate
Fix Version: Nightly Build
should be duplicate to myfaces-229, which is closed
> 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
> Fix For: Nightly Build
>
> 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.
