where is my custom controller?

what decides which forms appear for selection when you choose a custom controller? I created a form in v2 and was able to set the CC to be one of my other forms (navigator).
Now i have upgraded to v3 when I choose the Navigator property on my forms NONE of my forms are available for selection. Only

None
IGNORE
DEFAULT
svyCore_smtpDialog
z_functions_blank

appear as possible custom controllers. Why not mine?

Since Servoy v. 1 if you want a form to be selectable as navigator form you must unselect it’s “show in menu” property.

ok,
that was the issue. But it must have got checked on during the migration from 2 to 3. I certainly didnt do it…because I have selected that custom controller before in my solution…anyway, mystery is solved.
Thanks
