I'm getting this annoying warning
NLS missing message: CANNOT_FIND_FACELET_TAGLIB in: org.eclipse.jst.jsf.core.validation.internal.facelet.messages within a facelet page because the composite components namespace could not be validated. I think this is a JBoss Tools validation problem because the composite components library isn't located within the same Eclipse project.
I've found several validation entries under
Preferences > JBoss Tools > Web > JSF > Validation,
Preferences > JBoss Tools > Web > Knowledge Base > Validator and
Preferences > Web > JavaServer Faces Tools > Validation but could not find the right option to ignore the "NLS missing message".
Where could this warning message be disabled? Thanks for advice!
