Hello,
The txtName field has the .setOutputMarkupId(true).
I have also added it to the form.
But it doesn't work howevere.
I have event tested adding it to the txtLink, but still no change.
However, the issue appears to come from the
txtName.add(new AjaxFormComponentUpdatingBehavior("change") {...}
If I comment out this part, the clear is done.
But I need to have this behaviour kept.
Could you please advise?
Thank you
