Hi Raj,
if i interpret your code snippet correct,
the selectOneListbox with the click/change facet is NOT inside the
partially rendered panel. This is the problem, only the content of the
partiallyRendered component is processed on the server.
you have two(tree) choices:
1. include the listbox into the renderedPartially scope.
2. invoke the processing of listbox lifecycle in your action.
UIComponent listbox = facesContext.getViewRoot().findComponent(<id
of listbox>);
listbox.processDecodes(facesContect);
listbox.processValidations(facesContect);
listbox.processUpdates(facesContect);
3.(experimental) use 1.1-SNAPSHOT version.
you can declare full page to be submitted (and processed) partially and
in your action method remove the page and add orderPanel from/to the
partially
component list.
Regards,
Volker
