Spring webflow + CDI

Question

Are Spring Webflow and CDI compatible? I'm having problems deploying the application with beans.xml(CDI) included.

I'm deploying on Jboss 7.1

If I run the application including /WEB-INF/beans.xml (CDI) I have this exception :

When I remove beans.xml, the application works fine.

Answer 1

They don't interoperate out of the box, but you can use something like http://seamframework.org/Seam3/SpringModule to bridge them.

However, the issue in case project seems to be JSF-related (and CDI just causes it to show up). I suspect that Spring Webflow's JSF handling is clashing with the JSF servlet, but can't be sure until this is reproduced.

It would be great if you could provide a way to reproduce this (i.e. do you see it with one of the sample applications?)
