Description Phong Le CLA 2011-11-15 22:33:41 EST 
Build Identifier: 0.7.0.20111007-0146

Try to create an wizard extension point that using org.eclipse.sphinx.emf.workspace.ui.wizards.LinkedFolderWizard and I got the problem as bellow:

Reproducible: Always

Steps to Reproduce:
1. Open Linked Folder creation wizard
2. Click [Varibale...]button to open  'Select Path Varibale' wizard
3. In 'Select Path Variable' wizard, click [New..]-> 'New Variable' wizard open
4. Input a name and indicate a target folder, click [OK]
-> New Variable is created and shown in the list  of path variables
5. Select the newly created variable 
-> Edit... Remove, Extend.. button is enabled
6. Select [Remove] 

Actual result : 
- the variable is removed
- The selection is lost 
- Extend...button is still enable-> Click [Extend..] button -> an error appears
in error log

Expected: 
When the selected variable is removed, 
the selection is lost, 
[Extend..] button is disabled as well.

As I debugged deeply in PathVariableSelectionDialog. I see that the [Extend..] button is not updated every [Add] / [Edit] or [Remove] button is clicked (except variableTable selection changed).

Currently, these buttons call PathVariablesGroup#updateWidgetState() after adding /editing or removing an variable to update their enable status. So that, I think we must modified PathVariablesGroup#updateWidgetState() to raise an event for PathVariableSelectionDialog can update the [Extend..] button as well as variableTable do with selection changed.
