By any chance are you using the text field as part of a data entry form or similar and then using submit at which point the error occurs? You might want to try this: 1) Click on the text field 2) Check the Properties sidebar, Data section 'required' is unticked If that doesn't solve it, the way I did on my project (done using JBP 2.4.1 as I haven't moved to 2.6 yet) was to check for the text field for null and then set it to be a value if null and set in the sessionbean. Assuming you are using a submit button, then put that check in the button_action() method. If you are setting data into the textfield, make sure it is in the prerender() method.
