Converter being called unnecessarily

[foxpv]

I created one form that fills object of the type X and record in the data base.

After that, I created other form that fills object of the type Y and record in the data base, and, the type Y have one attribute of the type X. So I created a converter for the type X.

If I go back to the first form and submit, VRaptor throws a NullPointerException at br.com.caelum.vraptor.http.iogi.VRaptorInstantiator$VRaptorTypeConverter.setPropertiesAfterConversions(VRaptorInstantiator.java:144)

Maybe it occurs because VRaptor recognize the converter of type X and try to use that to convert some attribute, but the first form don't have any parameter of type X.
