Subject [jira] [Commented] (MYFACES-3582) Unable to process ajax calls within nested Composite Components
Date Mon, 23 Jul 2012 12:21:35 GMT


Leonardo Uribe commented on MYFACES-3582:

Sounds something related to MYFACES-3383, which was solved recently. In theory, the problem
could be related to the resolution of targets attribute,  

<composite:clientBehavior name="change" event="change" targets="#{cc.clientId}:some-id-here"/>

The #{cc.clientId} seems to be unnecessary, but I don't know the details behind that.

Anyway we need first to try if the latest code solves the problem, and later if the error
persists, a more simplified/detailed test case. Otherwise, there is no way to advance further.

> I am unable to make ajax calls within nested Composite Components. The outer composite
could be just a wrapper. For the issue to appear it could be empty with only <composite:insertChildren/>
in it. 
> The inner composite component uses 
> <composite:clientBehavior name="change" event="change" targets="#{cc.clientId}:some-id-here"/>
> The event actually doesn't matter.
> The inner component receives an ajax call like this:
> <controls:listBox property="#{carDetailsMediator.carDetailsCarMakesListBoxProp}" 
> items="#{carDetailsMediator.carDetailsCarMakesListBoxSelectItems}"
> customId="carMakes" width="115" visibleLines="6">	
> 	<f:ajax event="change" render=":formID:carModel:combobox"
> 		 listener="#{carDetailsMediator.changeCarMake}" onevent="initComboboxes" />
> </controls:listBox>
> I tried to debug the myFaces 2.1.8 implementation and got to the point where in the lifecycle
of the process at step 5 - Invoke Application there were no events and therefore no listeners
were called.
> I tried the same setup, but without the outer Composite Component, everything worked
- the correct event was fired and the listeners called.
