[jira] [Commented] (SCXML-186) Groovy expression evaluator

    [ https://issues.apache.org/jira/browse/SCXML-186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13862094#comment-13862094 ] 

Adrian Crum commented on SCXML-186:
-----------------------------------

Another option is UEL. Take a look at JUEL.

One thing we learned in the OFBiz project is that Groovy turns every expression into a class. If you have many expressions, you can run out of permgen space. I'm not saying don't do it, but just be aware of the drawbacks.

> A Groovy expression evaluator for SCXML expression can offer richer functionality which cannot be supported by the other simpler expression evaluator.
