Some observations which may be of some help:

Using an error producing button the

Object: property is not  an integer
Object: value is not boolean (true or false)

errormessage is produced every time one opens and closes a scripteditor 
(just opening and closing, no editing).

I changed the errorDialog handler of the frontscript in the  btn 
"newobj"  first to catch the which parameter.
If the wrong error message is produced then the which parameter 
contains:

354,0,0
352,0,0
354,0,0
352,0,0
354,0,0
352,0,0
354,0,0
352,0,0
354,0,0
352,0,0
354,0,0
352,0,0
.
.
< from 28 to 136 times the above lines>
.
.
89,2,10,2
95,2,10
466,2,1
241,2,1,mouseUp
353,0,0,button id 1003 of card id 1002 of stack 
"/Volumes/Stashville/Teststacks/metacard_error_tester.mc"

The last 5 lines of which contain the right parameters.

  I am test running a workaround to the errordialog with no problems up 
to now.

on errorDialog which
    if length(which) > 5 then put line -5 to -1 of which into which  ### 
the change
   set the executionerror of card 1 of stack "Execution Error" to which
   modeless "Execution Error"
   send "refresh" to card 1 of stack "Execution Error"
end errorDialog
