Spring EL expressions not evaluated on transitions

[CannyDuck]

I migrated my web application from Spring Web Flow 2.0 to Web Flow 2.3. With version 2.0 I used JBoss EL as expression language with version 2.3 Spring switched over to Spring EL.

I have transition in my flows like:

<transition on="${messageContext.hasErrors()}" to="viewState1">

These expression does not work anymore with the Spring EL. The expression are not evaluated and the conditions does not match anymore.

Can somebody confirm that problem?

Try to use '#' instead of '$' and it works
