Hi,
I am having a problem with submit link. I used to have a form with a
regular link on it but then the form data would not get submitted. Now
I have replaced this by a SubmitLink and in my onSubmit() I do:
validate();
updateFormComponentModels();
// Remove messages cause by validation.
getPage().getFeedbackMessages().clear();
This is done to make sure all field values are available and that
validation is suppressed. The problem (see below) also occurs when I
don't execute the above statements in my onSubmit().
Now back button support is broken. The problem occurs when I click on a
link to edit an item to a collection. The result of clicking a link for
adding an item is that a new item is added to a list displayed on the
screen with a SubmitLink next to it for deleting it.
The problem occurs when I do the following:
- click on a link to add an item to a set, the item is now
added to
the list on the screen.
- press the back button, the item is now not present in the
list
(as it was before adding it).
- submit the form
The error I get is:

This could be a problem with versioning of the submit link. It occurs
with wicket 1.2.2. Any ideas anyone?
Cheers
