No editor descriptor Error in BW Tools with HANA Studio rev 82

Hello,

After upgrading to rev 82, when I go to the BW modeling tools within the studio, I get:

No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab error

After that it's not possible to view any Open ODS view or Composite provider (just a blank canvas) on the right side. If you exit the blank tab (X out) on the right side you get a null java.lang.nullpointerexception.

This was working fine with rev 74.

Thanks,

Manish
