Dialog Toolkit Plus 1.1.3 'NSThread doesn't understand the "isMainThread" message.'

Scripting Forums AppleScript | Mac OS X
#1

I encountered this error after a minor edit ( added an entry to a list of strings ) to a script app that utilizes DTP 1.1.3. I’ve included the library in the script app resources and had absolutely no issues with my team using this app on various systems OS versions etc. for several months.

The un-edited version of the app still launches and runs properly.

This error does not occur running the app in Script Debugger but appears when the app is launched. I could find no fix but reverting to 1.1.2 which does allow the app to run normally.

Is there a known cause or resolution for this on DTP 1.1.3?

Not that I’m aware of. The usual causes of that error are either the use framework "Foundation" statement missing, or AppleScript having a hissy-fit. But the latter is usually intermittent.

Thanks for the info Shane. Since I have a functional copy to test with I’ll take another crack at determining the trigger if not the cause. I have managed to make AppleScript angry a few times recently, requiring a restart before proper behavior was restored.
