EventLinks and their handlers
I am stuck on a rather silly operation. I have an eventLink in the tml and
it's event handler in the class like so:
tml -> < a t:id='postConversationLink'>click the link < / a >
class ->
@Component(parameters = {"event=postConversationEvent"})
private EventLink postConversationLink;
@OnEvent(value="postConversationEvent", component="postConversationLink")
void valueChosen()
{
System.out.println("annotated version");
}
void onPostConversationEventFromPostConversationLink()
{
System.out.println("convention version");
}
To me both the annotated version and the convetion version look correct.
However, for both i get the error: Request event 'postconversationevent' ...
was not handled.
>From the message it looks like the link is actually generating the event,
but somehow it cannot be matched to any of the two handlers.
Thank you,
Bogdan.

Cool, cheers Taha,
This took me a while to understand so I'll re-iterate for my sake!
You're saying for EventLinks we need to drop the "From" clause because
the event isn't acutally raised in the eventLink but the container, so
the following should work:
@OnEvent(value="postConversationEvent")
void valueChosen() {
System.out.println("annotated version");
}
void onPostConversationEvent() {
System.out.println("convention version");
}
Steve.

Hi
EventLinks have event handlers of the form
on'EventName'
and the event name defaults to the component id.
'FromComponent' is not going to work as the event is triggered in the container without reference to the component triggering it. This allows shorter url
