My understanding, from reading the documentation and looking at
Sketch and TextEdit, is that if your application wants to return
styled text that can be manipulated via. the Text Suite, your code
should return an NSTextStorage object when asked for the property
that contains the styled text.
In response to a request for a property in my application, I return
an NSTextStorage:
/* assign attributes to mutable attributed string here */
[retVal replaceCharactersInRange: NSMakeRange(0, [retVal
length]) withAttributedString: richText];
[richText release];
return retVal;
}
The AppleScript debug log tends to suggest that I've built the text
storage object properly (or at the very least, the attributed string)
but the script to retrieve this parameter still fails:

}
...could not be converted to an Apple event descriptor of type 'rich
text'. This instance of the class 'NSConcreteTextStorage' returned
nil when sent -objectSpecifier (is it not overridden?) and there is
no coercible type declared for the scripting class 'rich text'.
2005-06-30 01:12:22.245 MM[3895] Result: (null)
2005-06-30 01:12:22.245 MM[3895] Error: 8 "NSInternalScriptError"
I don't understand why my object "could not be converted to an Apple
Event descriptor of type 'rich text'". The declaration of "rich
text" was copied out of the NSTextSuite into my sdef.
So far as I can tell, TextEdit builds it's NSTextStorage object the
exact same way, and yet TextEdit seems content to convert the
NSTextStorage objects into "utxt" object descriptors.
Can anyone suggest why my code might be failing?
