I've got a model testbench which is linked to a data dictionary. In that model I used another model as model reference which is not linked to a data dictionary. All parameters of the model reference can be passed down to the model by using a mask or are defined in the model workspace so that it can exist independent of any data dictionary. When compiling, simulink tells me
Error in Model block [childModel]. Referenced model [childModel] is configured to use the base workspace. It must be linked to dictionary [...
Why is this necessary? I want my child model to be independent of the data dictionary so that I could use that model in other projects, which don't use that dictionary, as well.
