Description Dani Megert

I20100916-1954.

1. start with new workspace
2. create a Java project and a Java class
==> 'Toggle Mark Occurrences' tool bar button in disabled state but functionality is enabled by default.

Marking as 'major' as the state is always wrong.

Same problem with 'Toggle Java Editor Breadcrumb' tool bar button.

Comment 3 Praveen

2011-05-19 10:15:03 EDT

I noticed that ToggleMarkOccurrencesAction is not registered with any propertyChange listener. So, when the action is invoked through key bindings, there is no listener to update the model (or renderer) about the invocation. Similar is the case for the other actions.
However, when the ToggleMarkOccurrences ToolItem is clicked - SwtRenderer is invoked as it is registered for the selection event, and renderer takes care of updating the model.

Any thoughts whether HandledContributionItem responsible for adding the propertyChange listener to the Action (for updating the model) ?

Proposed patch

I have investigated further to determine the root cause of the problem. I came up with a draft working patch that un/selects the ToolItem based on the action/model selection state.

Please review the patch and suggest whether the code changes are according to the expected architecture. Thanks.

PS: I will polish the patch once I get suggestions/approval.

Praveen's patch v02

While this is not where I want to end up in 4.2, I think that Praveen's approach of hooking up the listener between the action and the model is a good one for 4.1.  I've updated Praveen's patch:

1) we don't need the model changes, we can use the transient object map.

2) the MenuHelper IContextFunction can instantiate the plugin action and hook up the listener to update the model when the action isChecked() changes.

3) the MenuHelper IContextFunction can return a simple Runnable to unhook the listener.

4) The HandledContributionItem can take care of triggering the hookup when the ToolItem is created, and using the Runnable to unhook the listener on dispose.

I don't think this is working properly when multiple workbench windows are up. I also somehow got into a state where no parts wanted to be active and only the 'Package Explorer' was ever the active part.

1. Wipe your inner's deltas.
2. Launch your inner.
3. Open a Java file. The 'Toggle Mark Occurrences' action is selected as expected.
4. Alt+Shift+O to disable it.
5. Ctrl+W and close your editor.
6. Open the file again.
7. Alt+Shift+O still works but doesn't toggle the tool item. Reopening the editor seems to solve and induce the problem in a looping fashion.
