You have two different version of Solder in your war.
I know that I have two versions, the problem is just this. Why? Why seam-faces depends of solder and seam-persistence depends of seam-solder?
I solved this problem using this version of seam-persistence:
<dependency> <groupId>org.jboss.seam.persistence</groupId> <artifactId>seam-persistence</artifactId> <version>3.1.0.Final</version> </dependency>
In home of seam-persistence a version used is 3.0 and this version has given problem with seam-faces because seam-solder apparently was replaced by solder.
Use the seam-bom artifact in your dependencyManagment section to make sure you have the correct versions for everything.
