update field onAfterChange event problem

[okaminer]

Hi
I'm trying to update one of the form field, after the user change it.
I'm checking if the user input is correct and then update the same
field (to the correct or empty string).
The problem is this, when I try to udpate the field which raised the
onAfterChnage event, I get the following error message:

"The number of calls in the onAfterChange event for a single update in
the data exceeded the maximum limit"

I guess that the problem is caused by the fact that changing the field
in the code raise the onChangeEvent aging.
So if anyone knows what is wrong or know a different way to update a
changed field please let me know.


thanks,
