hi,
i´ve written a validation, which validates some
inputs of a TextField.
Trying to make an added AjaxCoomponentUpdating-
Behaviour updating the component failed in the
way, that the component is only updated by ajax
after clicking the submit-button.
I didn´t find any hints why ajax is waiting for
clicking the button once?
I hope some of your hints will help me.
regards
Henning
