Hello!

I have a problem to restart a specific Flow in a Portlet Environment.
How do i (re-)start a Flow in a different Portlet? Do i have to use renderurl or can i use actionurl?
When i use actionurl i always get the following error:
Code:
org.springframework.webflow.execution.repository.BadlyFormattedFlowExecutionKeyException: Badly formatted flow execution key 'null', the expected format is 'The string-encoded flow execution key is required'
When i use renderurl i have to problem that sometimes the flow is still active and its hard for me to restart it properly. So i get the problem that the flow is still in a certain view.
Is there any way to do the restart or use an actionurl?

Thanks in advance,

Andy
