Hi everyone,
I have created a rcp app for demonstrating my problem. I would be really
grateful if someone could look at it.
It seems that the problem is related to the navigatorContent that
overrides other content. I've tried to debug and seen that the method
"Collection findPossibleLabelExtensions(Object anElement)"
of "org.eclipse.ui.internal.navigator.NavigatorContentService" returns
nothing in case of this error. Furthermore, the javadoc for this method
states that it should consider overrides, though for instance,
"findDescriptorsWithPossibleChild()" is called with a false value for
the toComputeOverrides parameter.
Anyway, I hope someone would look into this.

Hi,
If somebody appeared to be interested:
I still don't quite understand what is the expected behaviour here, but
I have managed to overcome this problem by specifying
InvokeAlwaysRegardlessOfSuppressedExt instead of
InvokeOnlyIfSuppressedExtAlsoVisibleAndActive in the policy drop down
for the override element in the navigatorContent extension.
