short length of flowExecutionKey

Hi,

I m moving from Spring web flow 1 to spring web flow 2. When i used webflow 1.0 the generated flow key was common for all states like "_flowExecutionKey=_cB991AE60-9F1A-C5D0-F745-0D817F5C0D39_k9364BE07-2413-78A7-3F6F-F0B8F226A40F" but while using the new version the executionkey generated is looks like e1s1 and changes for every state in the flow.

I want to maintain a unique flowId through out my web flow to be unique like it used to be in spring web flow 1.0. Could you please let me know how can this be possible.


please suggest any solution for this
