> Key: WICKET-6480
> URL: https://issues.apache.org/jira/browse/WICKET-6480
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 7.8.0
> Reporter: Sven Ackermann
> Assignee: Andrea Del Bene
> Priority: Trivial

> Hi,
> I recently had a problem with a SubmitLink where a user double clicked on it
> (in Chrome 60.0.3112.90). The form was submitted twice and the submit action
> executed twice. I even could reproduce this with 5 clicks resulting in 5
> submits.
> To fix that, I just replaced the SubmitLink with a Button where the browser
> submits the form only on the first click. Browsers can/do not prevent that
> for the Javascript that is used with SubmitLink.
> Javadoc of SubmitLink says "A link which can be used exactly like a Button to
> submit a Form.". That is not exactly true, because you have to be aware of
> the fact that it does not prevent multiple submits.
> My suggestion is to either put a warning about that in the doc or add a flag
> to SubmitLink that modifies the onclick-Javascript such that it will be
> executed only once per page.
> Thanks
> Sven
