Thanks Kieran,

I checked the EOModel attribute inspector and the width there was set to 9 (should have been 10). 

This fixed the problem.

Thank you!!

What does the field definition look like in the database schema (CHAR, VARCHAR, etc.)?

What does the EOModel attribute inspector look like?

Hello,

I am receiving the following error on WO 5.4.3 on OS 10.5.8 and Java 1.5
Does anyone know how to debug this?

It worked fine before, however, I needed to make a text field accept 10 digits instead of 9 and now its throwing this error when I try to save changes.  I checked the database field and that can accept up to 20 chars, so that end is good.  When I switch the maxlength and size of the textfield to 9 I don't get this error and it saves my changes, but when I switch to 10...something is definitely not happy :)

Thank you in advance,
Mersida
