[Decorator] Icons not refreshed [message #112883]

Hi RAP team,

We are using a decorator on a TreeViewer, showing when an item is locked.
Despite all our efforts (calls to TreeViewer#refresh() and to
DecoratorManager.update(MyDecorator.ID)), the icons are not immediately
updated when an item gets locked, although the
MyDecorator#decorate(Object,Decoration) method was called. Only after some
other action (opening another editor, etc.) do we see the change.

Do you have an idea as how to force a refresh?

Thanks for your help!

Hi Gilles,

is the change of the item's state triggered by an interaction of the
current user or by some background operation? In the latter case you
might need to force an update of the client. You could have a look at
UiCallBack#activate().

Thanks for your reply!

In fact we have both situations. One case is a simple decorator for locked
files. In another case, the decoration is the result of a rather long
computation, so we make it into an asynchronous job.

However, why don't you just setup a UI callback for the decoration job
itself? This would seem to solve both cases, right?

Again thanks for help!

Please try to enable asynchronous UI updates by calling
UICallback#activate( some id ). For a simple test, you can put this call
into your WorkbenchWindowAdvisor implementation.
