I’m using CallbacksExt as a 2nd extension in all my Component, but this way I cant use callbacks during init of my components (unless I delay execution)
Is it a good workflow to just inherit from op.TDModules.op(‘TDCallbacksExt’).module.CallbacksExt ?
Yes that is the way to go. You can inherit from the class in that module or you can put the module in a selectDAT so that you have a local version (in case you need to customize or debug). An example of the latter technique is in lister.
