Hello,
Consider my code underneath and following actions:
- Page has a form with a REQUIRED textfield and a button that updates that
textfield through ajax
- When clicking button the value in textfield is altered with 'hello' =>
Normal situation
- When clearing the textfield again, the onError action of the
AjaxFormComponentUpdatingBehavior is called,
because the value is empty and the field is required
- When clicking the button again the textfield is rewritten, but has an
empty value instead of 'hello' => ERROR situation
If my explanation isn't enough, please let me know and I try again.
Hope someone can test my code and tell me what I am doing wrong..
Many thanks, Marieke
