[jboss-user] [JBoss Seam] - Could not instantiate Seam component:

[pasmith]

Hi Everyone,

We are making a Seam application and we started with configuration files very similar to those in the booking and registration examples.

To start off we are creating a simple login screen very similar to the one found in the registration example.
However, when the login button we get the following:

Our Login and LoginAction class are pretty much identical to those found in the examples, what could cause this to happen?
