Hey,
Hm, sounds like a valid use case. Cant imagine a "real" use case currently but
that dosn't care. Open a bug report for it and i'll take care of it.
Thanks,
Martin

I wrote the code that used this quite a bit ago so I dont remember all the
details but basically the use case is as such:
I have an object A and an object B. One of A property is bound to B, but needs
to be converted. The conversion depends on one of the property of the B object.
For instance, a boolean may be true or false, and this would affect the way the
property is converted.
In such an use case it was useful to get the targetObject sent to the
conversion function.

Could you maybe describe that situation? Maybe there is already another way of
getting that done.

Depending on the use case. ;) I don't get exactly the reason why it should be
necessary.
What i would not do is to use the second parameter if no model is available.
Why not use the third one and give it a specific meaning in every case?
