[Uml-devel] Bugs in C++ and Java codegeneration of methods/interfaces

[Harald Wallus]

Hi all,

there is something different in codegeneration between C++ and Java, too:
In Java the Token String has a uppercase, in C++ not.
That is no a big problem, but when I use umbrello, often I get this 
mismatch.
On the one hand, I think that such kinds of problems can only solved 
with user-action in the gui.
On the other hand, I wish a language independed tool.
At least, you may need to build a transformer for the language 
dependended parts.

nice day
Harald
