Logic crashes on startInternalDrag

[Oli Ullmann]

Hello, everyone :-)

I have an FX plug-in and several panels that use the startInternalDrag function.

When I load the plug-in, open it, and then click on the panel to use the startInternalDrag function, Logic crashes.

If I open the user interface of another plug-in first and then open my plug-in, Logic does not crash.

I've already tried calling startInternalDrag only in if(event.drag). It still crashes.

ChatGPT says there are known JUCE issues here. Has anyone else encountered this problem, and is there a workaround? The AI is suggesting that I code the drag-and-drop functionality myself...

Thank you very much
Oli

P.S. That doesn't happen in Cubase.

Cubase using VST rather than AU, right?

What about another host, like Reaper, running the AU?

[Oli Ullmann]

@David-Healey
Right, AU.
I haven't tried another host yet. I still need to do that.
But it also happens with Christoph's drag snippet. So it's not because of my project...

[David Healey]

@Oli-Ullmann But is it only with AU... test in Reaper because it can use AU and VST

[Oli Ullmann]

@David-Healey
I'll do that tomorrow and get back to you then. :-)

@Oli-Ullmann as @David-Healey , + Ableton Live

@ustk
I don't have Ableton Live. Is there a trial version available?

I can't find any on the website...

event.drag will be triggered also when clicked
try event.isDragOnly

@Oli-Ullmann Mmm... I'm afraid you're right, the unlimited (but restricted) version I had was probably v11.
If you have any hardware, sometimes it comes with a free lite license of Live.
Otherwise you can still try v12 for 30 days...

@Oli-Ullmann I reached out to Ableton last year for a NFR copy of Ableton 12 to test plugins and they were more than happy to accommodate me. Worth a shot ;)

[Oli Ullmann]

@David-Healey
Both versions (AU and VST3) work in Reaper. So it seems to be a Logic issue. :-(
Any ideas?

@ulrik
Even with isDragOnly, Logic still crashes.

@ustk @HISEnberg
I saw that there's an affordable "Live 12 Intro" available. I'm going to buy it to give it a try. :-)

Can you recreate the issue in a minimal snippet?

[Oli Ullmann]

@David-Healey
Yes, I compiled @Christoph-Hart 's “Script Panel Drag Example,” and it crashes in Logic as well.
