Ok seem like there a couple of NPE's occuring.  I caught them by adding a NullPointerException breakpoint when starting the Seam wizard.

First is in JBossRuntimeWizardFragment.getErrorString(int) which is called by isComplete() at a time where the controls are not initialized...so I added a null check in getError to only evaluate if controls are created:

	private String getErrorString(int severity) {
		if(nameText==null) { // We haven't yet been created so don't know any errors yet.			
			return null;
		}
		if (getRuntime(nameText.getText()) != null) {
			return Messages.rwf_NameInUse;
		}

The above error is swallowed by WTP for some reason.

The other is similar, a method is called before the composite are initialized so the gives a NPE:
The stacktrace is:

And it happens on a clean workspace.

Create seam project
Create runtime (don't create server)
Create Server - Press Finish and then the NPE occurs.
