[jira] Resolved: (SCXML-43) SCXML parallelism
[ https://issues.apache.org/jira/browse/SCXML-43?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rahul Akolkar resolved SCXML-43.
--------------------------------
Resolution: Invalid
Thanks for the details -- the SCXML document and state machine diagram. At first glance, it does not seem to be a problem with the Commons SCXML library. I will respond to your email on the user list (titled "SCXML error") in a few minutes.

> Hi there,
> We are trying to use SCXML for one of our use case where we have lots of state transitions and event generated. I am having problem with having multiple transitions defined within a state. I am attaching herewith the state diagram and the SCXML that I have tried creating. Please give your suggestions on where I am wrong in defining the SCXML.
> Thanks

> I am not able to attach the state diagram here and is there any forum where I can send attachments.
