Didn't something change recently with the recursion limit? Maybe
something in the engine changed too. Also, I've had a few cases where
inserting a breakpoint changed the way the handler behaves, which makes
me think in this case the debugger is managing the recursion somehow.
I'm just guessing.
Mostly what I wanted to say is that usually I avoid the whole issue like
this:
on hCheckEntry pData
repeat until pData is an integer
ask warning "Please enter only whole numbers!" with pData \
titled "Enter A Number"
if the result = "cancel" then exit to top
put it into pData
end repeat
put pData into me
end hCheckEntry

What is wrong with this Script logic?
I've been staring at this too long and can't figure out what's wrong.
1) New Main Stack
2) Add 1 plain field
3) Set the flds Script to:
on closeField
hCheckEntry me
end closeField
on hCheckEntry pData
if (pData is not an integer) then
ask warning "Please enter only whole numbers!" with pData titled
"Enter A Number"
put it into tAnswer
if (tAnswer = empty ) then
exit to top
else
if (tAnswer is not an Integer) then
--breakpoint --Pos 1
hCheckEntry tAnswer
--breakpoint --Pos 2
else
put tAnswer into me
end if
end if
end if
end hCheckEntry
If I make the Pos 1 breakpoint active and Pos 2 inactive, then enter A
into the field the ask Dialog comes up with A. If I enter B into the
Dialog then the Dialog reappears with B; this continues for all the
bad data I enter. If I then enter a number or click "Cancel" it all
completes as it should. OK.
If I comment out Pos 1 breakpoint and make Pos 2 breakpoint active,
then when I enter A my ask Dialog comes up with A, BUT if I then enter
B I get an IDE window:
The handler: hCheckEntry has reached the recursion limit of: 400000
If I click the "OK" button on this window to make it go away I am then
presented with my ask Dialog with the B as the default.
If I press "Cancel" my ask Dialog Box comes back with "OK" as the
default answer.
If I press "Cancel" again it finally cancels.
At no time does the debug window come up at my breakpoint.
If I turn Debug Mode OFF, and repeat the above, after I enter B in my
ask Dialog I get the IDE Errors widow come up with:
Type: Handler: can't find handler
Object: fldTest
Line: hCheckEntry tAnswer
Hint: hCheckEntry
My Ask Dialog Box is also presented with B as the default. If I press
"Cancel" my ask Dialog comes back with "ask warning" as the default
answer. If I press 'Cancel' again, it finally cancels.
So why is my script having a recursion problem or not finding the handler?
I'm sure I've written many many similar data checking scripts over the
years and not had this happen.
