[news.eclipse.platform] Re: persistent property and open resource

[carl@xxxxxxxx (Carl Hagenmaier)]

I have verified that the decorator is not being called.

I created a new extension in my plugin.xml

  <extension point="org.eclipse.ui.decorators">
     <decorator
           adaptable="true"
           class="jtocsharp.TestDecorator"
           icon="icons/sample.gif"
           id="JtoCsharp.decorator2"
           label="Resource Decorator 2"
           lightweight="true"
           location="TOP_RIGHT"
           state="true">
        <enablement>
              <objectClass
                    name="org.eclipse.jdt.core.ICompilationUnit">
              </objectClass>
        </enablement>
     </decorator>
  </extension>

If the resource (in this case a .java file) is not open, the decorate 
method of my decorator class TestDecorator is executed.  If the resource 
is open, the decorate method is not called.  Thinking perhaps that opening 
the file might change the objectClass (so that it is no longer an 
IComplilationUnit), I changed the enablement to java.lang.Object.  This 
made no difference.

It must be that the something in the event processing that occurs as a 
result of the "touch" is suppressing the decoration because the file is 
open.  There must be some (not obvious to me) reason why this behavior is 
desired.  In any case, I need a way around it.
