Description saadia dhouib CLA 2011-10-12 11:36:22 EDT 
When doing programmatically a refresh on a project in the workspace, the diagrams and tables disappear from the modelExplorer.
The code to do do the refresh is the following:

	IProject projectToRefresh = editor.getProject();
							try {
								// synchronize changes with Workspace
								projectToRefresh.refreshLocal(IResource.DEPTH_ONE, null);
							} catch (final CoreException e) {
								Activator.logException(e);
							}
							
							
this the error stack:

Comment 1 Vincent Lorenzo CLA 2011-10-13 08:16:55 EDT 
Should disappear after the Papyrus refactoring. 
Another way to reproduce this bug : 
1/ Create new Papyrus project
2/ Open the modelexplorer
3/ Do a modification in your model, without save
4/ Open another editor (not Papyrus)
5/ CTRL+Shift+S (Save All)
	-> the current editor is not Papyrus, so we can't find it to get an IpageMngr.
Comment 2 Vincent Lorenzo CLA 2013-03-13 09:01:53 EDT 
I ca'nt reproduce this bug on Papyrus 0.10. I close the bug
