Description of problem:
When copying existing project, Designer tries to create new globals file in VFS. This fails with Error modal dialog "File "/DEF/global" already exists."

Version-Release number of selected component (if applicable):
BRMS ER5 / BPM Suite 6.2.0 ER5

How reproducible:
Always

Steps to Reproduce:
1. Go to project authoring and create new project "ABC"
2. In the project editor that is opened click 'rename' and select new name for the project "DEF"

Actual results:
Modal dialog "ERROR: File "/DEF/global" already exists."

Expected results:
No error when copying the project.

Additional info:
Comment from Michael Anstis:
Tiho will need to ensure Designer's org.jbpm.designer.repository.vfs.VFSRepository.createGlobalDirOnNewProject() method checks whether files already exist.

Please see the log. Looks like you'll need to check if files already exist in the "global" workspace before creating them.
