Description:
===========
Attempting to adjust the directories in a project by draging and dropping concepts to a different folder. After that, Studio could not build the ear file correctly and threw a NullpointException.


Environment:
===========
TIBCO BusinessEvents - 5.x
OS - all

Cause:
===========
References were broken after dragging and dropping object defintions.

Resolution:
===========
Drag and drop is not supported in Studio. The right way is using Refactor:

1). right click on the concept/event

2). select refactor -> move

3). select new position in project

Always use this refactor option if you want to do any changes to the project.
