I've been working on a transformation for C# but the model that I need to transform uses multiple inheritance. C# does not support multiple class inheritance, though it does support implementation of multiple interfaces. So in my transform, I'm checking if the class is inherited by a class that uses multiple inheritance and if it is, I'm trying to create an interface and a class from the original class and change all of the original generalizations to point to the newly created interface.
The code in the intermediate file looks right to me and everything works except the associations to the interface created by the transformation. I've pasted the text from the intermediate file specific to the associations that are not working, the transformation code and a link to the full text of the intermediate file below. There is an EXEC_ADD_IN call to determine if the class is inherited by a class that uses multiple inheritance in the transformation and I have not posted the addin code but I have tested the function used and verified that it operates as expected.
Does anyone see what could be causing the problem? Any help will be greatly appreciated.
