Hello!
I have a similar issue with the error FRM-41351 as discussed in https://community.oracle.com/tech/developers/discussion/64295/frm-41351-cannot-navigate-out-of-current-form
In my case, I have a JTable, I drag and select multiple rows and when I press a button that calls a different form, a FRM-41355: Cannot navigate to form 'the JTable form'. And when I go back, it gives - FRM-41351 Cannot navigate out of current form.
Maybe setting the preference NAVCCF=NO would help, but I don't know how to do that. Can you help me guys?
