Hello, I'm getting a
"WELD-001409 Ambiguous dependencies for type [ELContext] with qualifiers [@Default]" error message when trying to deploy a 3.1.0.Beta5 SEAM3 project under JBOSS 7.0.2. Any ideas why this might happen?
Below the stack trace you'll find my pom.xml.

As I'm new to SEAM3/WELD, your help is really appreciated.
