Error "Encountered an improper argument" during code gen

[Thomas Arnbjerg]

When I generate C++ code from two interface classes I get the error message "Encountered an improper argument".
It has worked before for the two interfaces in question.
The error does not appear for several other interface classes with the same number of parameters and data types.

Any ideas?

Ok - it's an internal error somewhere. If i clone the two interface classes (i.e. identical) I can do the code generation.

So that's a workaround.
