Comment 1 Alexander Nyßen 2011-01-03 15:57:40 EST

Well, with the information you have provided I am not able to reproduce the issue.

What Linux platform are you using? Can it be reproduced using one of GEF's reference examples?

Comment 2 Alexander Nyßen 2011-01-28 17:43:48 EST

Resolving as invalid as there has been no response and it is uncertain that this is indeed a GEF issue. Please re-open and provide more data in case this still holds.

Comment 3 Eddie Galvez 2011-04-15 12:58:25 EDT

FYI we see this too in our product, as our users, on Linux 64 report this when opening our GEF editors.

Ubuntu tends to be the linux platform in use

Comment 4 Alexander Nyßen 2011-04-15 13:06:59 EDT

Could you please try this again using the Debugger with an exception breakpoint to check, whether any exceptions are occurring prior to this?

Comment 5 Eddie Galvez 2011-04-15 13:14:40 EDT

I just tried with a RuntimeException, caught or uncaught, breakpoint. Nothing hits, error log shows what I pasted. I'm going to step through a bit...

Comment 6 Eddie Galvez 2011-04-15 13:23:27 EDT

what can I say, it's just as the stack trace indicates -- gtk printer enumeration, gtk event loop, the click on the package explorer (from the double click that led to the editor open request) is (re?)processed and a new activation event tried to happen while the editor was due for activation.

GEF's print action might need to just have a workaround for linux platforms, perhaps enabling optimistically and then executing on the ui thread later to really compute enablement?

I would rather not add any platform-specific workarounds to GEF in case the problem can be tracked down to SWT inconsistencies. I expect this to be the case here.

Comment 8 Eddie Galvez 2011-04-25 11:47:38 EDT

What can be done to make this a work item for the SWT team?

Comment 9 Maarten Bezemer 2012-05-02 08:32:18 EDT

I have also this problem.
I am running on Ubuntu 64-bit. Eclipse build identifier: I20110613-1736 and GEF version 3.7.2.v20110927

It triggers when I double click on a (custom) marker.
Also when double clicking on a file in the package explorer triggers this problem.

In my gotoMarker() method I use this code to select and reveal the edit part that belongs to the marker.

getGraphicalViewer().select(editPart);
getGraphicalViewer().reveal(editPart);

Is there way way to circumvent this error/warning?
