I noticed a mismatch between the registration of the modeling selector extensions and the code in the selector service that looks up these extensions.

There are 2 selection extensions in org.eclipse.ease.modules.modeling:

   <extension
         point="org.eclipse.ease.modules.modeling.selector">
      <selector
            id="GMFSemanticSeletor"
            impl="org.eclipse.ease.modules.modeling.selector.GMFSemanticSeletor"
            priority="50">
      </selector>
      <selector
            id="GMFNotationSelector"
            impl="org.eclipse.ease.modules.modeling.selector.GMFNotationSelector"
            priority="45">
      </selector>
   </extension>

The SelectorService is looking up the extension with the wrong ID and wrong name.

I also noticed that there are several EASE modules that are not included in the plugin.xml extensions.

I propose the following fixes:

I have to admit I never looked at the modeling modules much. Fixes are much appreciated, but you would have to provide them as gerrit patches. Please see the contributor guide, which I just updated recently.

For some of the additional modules I question their usefulness. For example DialogModule and WorkbenchModule both share a getActiveShell() method. selectFormList() might be better moved to the UI module and be refactored to something like showSelectionDialog(...).
I also am not sure about all the functions in the WorkbenchModule(). Does it make sense for a script to call getActivePage()/getActiveWindow() ? Might be a use case, but what to do in a script with such objects? Nevertheless, questioning the use case is a differnt story, so please add it to a gerrit commit.
