Bug with coercions and keyAppHandledCoercion?




I've been tracking down an error that occurs when scripting my app. At first I assumed that it was a bug in my homegrown Carbon-based Apple Event handling code, but now I'm starting to think it might be a bug in Applescript...


Recently, I added code to set the keyAppHandledCoercion parameter in the reply to typeBoolean true when the requested type matched my class type. This was enough to make simple coercions like these work correctly:

	tell application "Life Balance"
		task 1 of document 1 as task
	end tell

	tell application "Life Balance"
		item 1 of every task of document 1 as task
	end tell

However, when I try something more complex:

	tell application "Life Balance"
		item 1 of (every task of document 1 as list) as task
	end tell

I get the error:

	Can't make <class Task> id "1797703789526674182" of
	document id 1 of application "Life Balance" into
	type <class Task>."

The reason I think this might be a bug in AppleScript is that in all three cases I'm returning exactly the same result from my core/getd handler:

reply = 'aevt'\'ansr'{ '----':'obj '{ 'want':'Task', 'from':'obj '{ 'want':'docu', 'from':''null''(), 'form':'ID ', 'seld':1 }, 'form':'ID ', 'seld':"1797703789526674182" }, 'idas':1 }, err = 0

Is there a chance that Applescript is failing to notice that I've set the keyAppHandledCoercion parameter in this third case?
