Hi all,
I have a plugin uses replace_knobs() to create knobs dynamically:
replace_knobs( knob( "my_knob" ), num_of_dyn_knobs, (
&createKnobsCallback ) )
Nuke crashes when replace_knobs() returns, even the createKnobsCallback()
does nothing:
void createKnobsCallback( ... )
{
/// nothing to do
return;
}
here is the stack trace:

If I use the knob pointer instead:
Knob* myKnob = knob( "my_knob" );
replace_knobs( myKnob, num_of_dyn_knobs, ( &createKnobsCallback ) )
then the former crash is gone, but Nuke still crashes when calling
Knob::set_value() or Knob::set_text() during replace_knobs():
void createKnobsCallback( ... )
{
...
myFloatKnob->set_value( 1.0 ); /// crashes
myStringKnob->set_text( "abc" ); /// crashes
...
}

Is there anything I should be aware to?
Thanks a lot,
