Code checking and generation

[Dexxter]

Hi!

When i reverse-engineered my code from vs 2003 ea and opened the diagram in
visio i was told of some semantic errors:

UMLE00046: TheObject[Parameter] : [Parameter - WFR1] - An interface cannot
be used as the type of a parameter.

Though the vb compiler doesnt bother, visio seems to. Does anyone know how
to fix thise?

And when i then decided to add a couple of attributes and operations and
pressed generate code, all my previous code is lost and replaced by visio's
code stubs. Any suggestions on how i can just update my code and not
starting all over from scratch?

Thanks in advance!
