Finally found a way to achieve this : just add support for StreamPageContent
handling in the ComponentEventResultProcessor (in my module) :
@Contribute(ComponentEventResultProcessor.class) @Ajax
public static void provideStreamPageContentAjaxComponentEventResultProcessor(
MappedConfiguration<Class, ComponentEventResultProcessor>
configuration) {
configuration.addInstance(StreamPageContent.class,
StreamPageContentResultProcessor.class);
}
Now, I can do this :
@OnEvent(MY_EVENT)
Object onFetchGridContent(){
return new StreamPageContent(GridContent.class, contentContext);
}
and provide the event URI to the js component.
RFE : Couldn't this be done by default in TapestryModule?
Regards
Guillaume
