Description Tod Creasey

2002-04-15 09:15:26 EDT

I have a workbench with the Resource, Update and PDE perspectives open. PDE is 
the active perspective. I had all of Eclipse in my workbench as binary projects.

I selected Ctrl Shift T to open type on WizardExternalProjectImportPage and I 
got the following exception
