--------------------------------------
Summary: SubmitLink can submit the form multiple times
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
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
