LinkageError / NoSuchMethodError when using with JSF2

Hi,I'm setting up my Activiti app with Tomcat, Spring, and JSF 2 (MyFaces) Frontend.The problem is clashing EL library used by Activiti (JUEL) with the EL specification used by Tomcat and MyFaces.By default, I get a LinkageError for ELResolver interface when starting the MyFaces listener in Tomcat.F

Well, I found a way:
I needed to remove JUEL from my WEB-INF\lib when I added it to tomcat's lib folder. It works now.
But a solution for this issue that doesn't involve changing the Tomcat's lib folder (anything outside the context root) would be nice.
I believe there's an issue registered for it in Activiti's JIRA.

It's a known issue at the moment, and we are working on it to resolve it.

The workaround is indeed as you describe: remove the juel libs from the Tomcat lib, which removes the clashes with the EL resolver of Tomcat (which is a different version of EL)
