Hi,
The captioned module has been deleted.
It contained 2 classes:-
1) ConstraintValueHelper - I have moved elsewhere (I don't think anyone uses it, as it's use was specific to various Drools Workbench screens).
2) Observer - I have deleted this. It was only used by 1 screen in kie-wb-common (the POM Panel in the Project Editor). It's use was flawed and hence it might as well not have been used.
