Description of problem:
The rename functionality for processes doesn't work consistently. Sometimes process' name attribute is changed, sometimes it is not (although bpmn file name is changed).

Version-Release number of selected component (if applicable):
BPMS 6.0.1 CR1

How reproducible:
always

Steps to Reproduce:
1. Create a process named 'ProcessName' in some package, say 'my.package'.
By default, the attributes of the process are generated as:
id=my.package.ProcessName
name=ProcessName

2. Rename the process in designer, say to 'NewName'
bpmn file is renamed successfully
id remains unchanged
name=NewName --> new name is based on what user wanted

3. Rename the process for 2nd time, so that the name begins with number (e.g. 10LittleIndians)
bpmn file is renamed successfully
id remains unchanged
name=NewName --> new name remained the same as before (perhaps designer doesn't accept number?)

Actual results:
The process id remains the same all the time.
The name attribute sometimes changes, sometimes it doesn't

Expected results:
Whenever bpmn file name is changed, the process' name attribute should change to the same. Also I would expect, that process ID should also change based on the new file name, since it was generated based on the file name in the first place.
