STS validator problem on SWF dynamic transition target

When I use a dynamic transition target like

Code:

---

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

---

STS web flow validator reports an error like:

Quote:

---

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

---

If I use

Code:

---

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

---

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

Quote:

---

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).
