Hello,
I have mine own widget which is rendered with IFrame and puts the data in request:

test : function(xmlData){
if( !org_eclipse_rap_rwt_EventUtil_suspend ) {
var wm = org.eclipse.swt.WidgetManager.getInstance();
var gmapId = wm.findIdByWidget( this );
var req = org.eclipse.swt.Request.getInstance();
req.addParameter( gmapId + ".xmlData", xmlData );
req.send();
}
}

My widget triger an dataChanged event which is handeled in View, the handlet set a text proppert in text widget on the same view. When the method test ist called the dataChanged event is trigered, it is handeled and the text property is set but not appears in client.
What I have to do to transport a new value to client?
best regards
Bogdan

Hi Bogdan,
are you sure that the text property is set in the Text widget on the
server-side? Are your listeners notified for dataChanged event? One of
the common mistakes with custom event processing is, that the event
firing is not wrapped in ProcessActionRunner like:
ProcessActionRunner.add( new Runnable() {
public void run() {
// create event and notify listeners here
}
} );
Best,
Ivan

Hi Ivan,
thx for your reply. I have found a reason of my problem - i have called setText to early and it was overwritten.
Could you tell me where can I find a docu for defining and handling widget events?

best regards
Bogdan

Hi Bogdan,
there is no specific document for this. The main point is to remember
that the events in RAP are processed in PROCESS_ACTION phase. Thus, you
need a ProcessActionRunner if you fire an event in READ_DATA phase for
example.
Best,
Ivan
