[mdt-papyrus.dev] contributorId of properties view

[沈謇 <drsj92@xxxxxxxxxxx>]

Hi, 

I'd like to extend the tabbed properties view of papyrus, for example, add a tab called "myTab", and I wrote these simple lines: 

  <extension point="org.eclipse.ui.views.properties.tabbed.propertyTabs">

      <propertyTabs contributorId="TreeOutlinePage">

         <propertyTab

            label="myTab"

            category="org.eclipse.papyrus"

            id="mytab"/> 

      </propertyTabs>

  </extension>

I found this contributorId and category in org.eclipse.papyrus.views.properties, but it seems not correct, can you give me some advices?

Thank you!

Regards,

Jian
