Bug 1256400

Description of problem:
If you will add variable name with whitespaces in new DataMapper editor it will be shown in Assignments property like normal variable: "[din]Some variable=Some value". But after saving and reopening process it will be "[din]=Some value" and if you will open the DataMapper editor there will be no [incorrect] variables to show. Correct variables will be present.

Version-Release number of selected component (if applicable):
6.2.ER1

How reproducible:
always

Steps to Reproduce:
1. Create Business Process with Manual Task
2. Add Input Variable throw Assignments (DataMapper) Editor: [Name="Some name", type="String", Source="Some value"]
3. Click "Save" button
4. Assignments field will contain string "[din]Some variable=Some value"
5. Save Business Process
6. Reopen Business Process
7. Assignments field will contain string "[din]=Some Value"
8. Open Assignments (DataMapper) Editor. No variables will presented at all.

Actual results:
Point 4. contain mapping for variable with wrong variable name
Point 7. Assignments field have no actual name of variable at all
Point 8. Before you open an Assignments (DataMapper) Editor you saw some data in Assignments but in editor you see nothing.

P.S. If you will try to type wrong variable name in other ways (for example variable#2). You can see it like in this issue (Point 4.), but after saving you can't to open this Business Process in normal way (You will see XML editor for Business Process instead). May be it is another issue.
