Description of problem:
Designer in BPMS displays just empty page on EWS. Readonly mode in Process Instance View do it as well.

I can not find Error message which should be related with this issue in server logs.

Note: Designer in BRMS works fine on EWS.

Version-Release number of selected component (if applicable):
6.0.1 ER2 BPMS

How reproducible:
BPMS ER2 + EWS

Steps to Reproduce part #1:
1. Create new process

Actual results:
Instead of Designer there is just a grey area. HTML tag "body" contains just script but not others elements which should be a toolbar, property bar, etc.

Process definition is created in repository.

Expected results:
Show designer without any problem.

Steps to Reproduce part #2:
1. Run process definition
2. Show Instance view (Read only mode of designer)

Actual results:
Same result as has been mentioned in part #1

Expected results:
Show designer in read-only mode and mark nodes which were executed.
