I have a variant block that's within a model reference. I'd like to be able to control which variant is selected from a mask pop menu on a block that contains the model reference, but I can't figure out the proper functionality to accomplish this. If the model reference is a subsystem block instead of a model reference, then I can put code in the pop menu mask parameter's callback code to set the "LabelModeActiveChoice" on the variant block.
I have tried:
1) Using a Subsystem Reference block. This doesn't work, as I get a "Incorrect to modify Subsystem Reference block using callback code" error.
2) Piping the selection via a parameter on the model reference block and putting callback code on a initialization code of a mask on a block containing the variant block. This break because it's trying to change the variant during model init.
