WELD-001318 AmbiguousResolutionException with Converter having subclass

fabmars Mar 29, 2012 9:40 PM

I'm using GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0

On some page I have <rich:inputNumberSpinner label="Count" value="#{orderLine.quantity}" converter="IntegerOrNullConverter".../>

The converter to use is explicit. But I also extended that converter class twice for other purposes.

When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.

SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters (the one I explicitly asked for for and the 2 subclasses) and it complains. I strongly believe calling BM#resolve here is wrong.

GRAVE: org.jboss.weld.exceptions.AmbiguousResolutionException: WELD-001318 Cannot resolve an ambiguous dependency between [Managed Bean [class org.mars.toolkit.jsf.converter.MonthConverter] with qualifiers [@Any @Default], Managed Bean [class org.mars.toolkit.jsf.converter.IntegerOrNullConverter] with qualifiers [@Any @Default], Managed Bean [class org.mars.toolkit.jsf.converter.YearConverter] with qualifiers [@Any @Default]]
