[ews.eclipse.technology.rap] Re: Selection Listener Problem

[Ivan Furnadjiev <ivan@xxxxxxxxxxxxxxxxx>]

Hi Kathiravan,

your code looks good, but I can find where is the place where the 
selection event is processed on the server side (in readData() or inside 
the designWidget.setSelectedPart). You need to call 
ControlLCAUtil.processSelection(Widget, Item, boolean) in readData() to 
fire a selection event based on this client code - req.addEvent( 
"org.eclipse.swt.events.widgetSelected", designWidgetId ); .

Best,
Ivan
