hi there,

i'm trying to implement a dynamicly created contextmenu, called from within a datatable.

my problem is

(a) i dont get my code to work on the oncontextmenu event
(b) i dont get the right property in my backing bean

here is the relevant code-snippet (taken and modified from max katz's practical richfaces, chapter 9, menu components):

<rich:datatable...>
...
<rich:contextMenu submitMode="ajax" id="cm"
     binding="#{contextMenuHelper.contextMenu}"/>
...
<rich:column 
     <f:facet name="header">
...
     </f:facet>
     <h:graphicImage ... />
     <rich:toolTip...  />
<a4j:support event="oncontextmenu"
     oncomplete="#{rich:component('cm')}.doShow(event, {})"
     actionListener="#{myAction.myListener}" reRender="cm" >
     <f:setPropertyActionListener value="#{myItem}"
               target="#{myAction.item}" />
</a4j:support>
</rich:column>
...
</rich:datatable>

(the contextMenuHelper is EVENT-scoped and holds the dynamically rendered context-menu)

Okay, back to my problems:

- if i rightclick in the column, no methods are called at all, and i get a tiny, empty context-menu (just 2 pixels or so)

- if i change the event of the a4j-support to onclick, the a4j action listener is called, but before the property action listener sets its value - obviously resulting in a NPE

- if i change my bean-code to be NPE-safe, for the sake of the example, i see that the context menu is dynamically created, but not for actual clicked data row, but for the last one... (as expected)

any ideas what is wrong?

cheers,
jan
