You shouldn't need to do this. The FL_FORM structure contains a
pointer to the fdesign generated structure FD_whatever structure. You
can fish it up as follows:
void my_object_cb( FL_OBJECT *ob, long data )
{
FD_myform *form = ( FD_myform *) ob->form->fdui;
[...]
}
I suspect this is the source of your problem.
