Hi everyone, I have to modify one class in compiere-all, so I've made a copy, in order to do not modify the original one and  I've modified it. But I don't know how to tell to the other classes, to not use the old one.
I do hope that I don't have to modify all the classes which are using it manually, and change the "import", or other stuff like that.
I've heard about modelvalidator, but I don't know how to proceed. The class i'm trying to modify is the "VlocationDialog"

Thanks
