SoapUI Pro & versioning: unwanted changes in project file

Hi,

I have a problem with SoapUI adding unwanted changes to composite project files. Just loading and saving for example results in this difference in files:


before:
anonymous="optional" xmlns:con="http://eviware.com/soapui/config">

after:
anonymous="optional" id="5d9264a3-9081-4aea-92ef-1fd1d8b7b5a4" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:con="http://eviware.com/soapui/config">

this causes many false "changes" detected by versioning system, and makes cooperation quite difficult (merging etc).

The same was reported

Does anyone know how to prevent this? Is it a bug?

Thanks,
Silvestr Peknik
