AW: [rap-dev] Question concerning UICallBackUtil

["Stefan Roeck" <Stefan.Roeck@xxxxxx>]

Hello Sebastian,

first of all: please use the RAP newsgroup for those kind of questions. You'll sometimes already find the answer there as well :-)

The order must be as following:
1. UICallback#activate(id)
2. Display#syncExec(uiUpdateRunnable) in your asychronous method (i.e. callback from Webservice)
3. updating the widget in the uiUpdateRunnable#run() and call UICallback#deactivate(id)

Regards,
Stefan.

Hello again,

damn fast answer. OK, I don't know exactly how to use it. Im my
application I call a Web Service asynchroniously and in the callback
method I'd like to set some Text.setText (SWT Class). But
unfortunately, I get an error claiming an invalid thread access.

UICallBack.activate(id) should be called before the asynchronous call,
right? Is this an arbitrary async call or should I use
Display.asyncExec()?
