Hello Marc, I think you want the @Component annotation instead of @InjectComponent. The latter is "Used exclusively inside a mixin to connect the mixin to the component to which it is attached."[1]
I haven't tested whether this will solve your problem, but it seems likely. A good starting point for basic form validation is probably the 'Input Validation' page of the online documentation[2]. It comes with a simple example and a lot of useful info. As an aside, you can use Form.recordError() as a convenience around getDefaultTracker().getErrors().add(). HTH. Cheers, lasitha.
