I noticed that it was not the actual "Enable FM" that made it crash, I also changed the Carrier and Modulator indexes in the same callback and that made it crash.
@trillbilly try the command auval -help, it will give you a list of the available commands. IIRC the command you're looking for is auval -v + the specific code of your plugin (but i'm unable to check right now, I'll take a look when I'm back at home).
@danh be careful before deleting backups and passwords too. I made this mistake. I had to wait 3 months for Apple to release me 2 certificates. I used all 5 ^^
@lindon Digging up this old thread as I was looking for something else. Just thought I'd let you know that I added a Panel.getChildComponents() function a few weeks ago. https://github.com/christophhart/HISE/pull/235
