STS validator problem on SWF dynamic transition target

[qs.dvogt]

When I use a dynamic transition target like

<transition on="back" to="#{myFlowAction.breadcrumbBack(myFlowBean)}"/>

STS web flow validator reports an error like:

Element transition references a non-exiting state "#{..."

If I use

<transition on="back" to="${myFlowAction.breadcrumbBack(myFlowBean)}"/>

the STS validator stops reporting that error, but I run in an exception:

Cannot find state with id '${myFlowAction.breadcrumbBack(myFlowBean)}'

Can we switch the EL? (and if so - to what?) Or can we reconfigure the STS SWF validator (this should be the way I suppose)?

Thank you for any suggestion.

Regards.

No ideas on this validation problem?

You found an honest to goodness bug. Looks like the current Web Flow uses the Spring Expression Language, while older versions of Web Flow used Unified EL. See http://static.springsource.org/sprin...erence.html#el

Unfortunately the validator just hadn't been updated to compensate for this change. Fixed for the 2.9.0RC1 release. Cheers.

Thank you. I think best would be providing the option to decide which EL to use - at least for older SWF versions (I think it was possible to change the EL there).
