Because if you click on the submitlink that call:
wicket.markup.html.form.Form.dispatchEvent(Form.java:1205)
shouldn't happen at all. Because there shouldn't be something in this url:
String url = ""> if (!Strings.isEmpty(url))
{
dispatchEvent(getPage(), url);
}
because the hidden field id is replaced with the button name.
So i dont know why you get an url or a string there.

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:
The error I get is:
- 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

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