Hi,

I try to disable a toolbar item with AbstractHandler.setBaseEnabled method but it does not work. To reproduce the problem please follow below instructions,

1- Create 3.x rich client application with "RCP application with a view" template.
2- Create a command and default handler (with extending AbstractHandler).
3- Call setBaseEnabled(false) method in execute method.
4- Add toolbar menucontribution to plugin.xml.
5- Add created command to toolbar menucontribution.
6- Run the application.

It works with kepler (4.3.2) but it does not work with luna (4.4.0).

Thanks.

I get the same problem.
Did you manage to resolve this or find a workaround?

When you select an item from the list, toolbar item is updated. As a workaround I just get the selected item from the viewer (which is treeviewer for me) and reselect the same item. This way toolbar item(s) are updated. Reselection of the item is below;

ISelection selection = viewer.getSelection();
if(selection != null)
{
    viewer.setSelection(selection)
}

Does your Handler implements IElementUpdater ?

then you should try with that and all call the right ICommandService in your Execute Method of your handler
