Race condition when submitting a form in "afterChange"-handler (tabs.js)
Reported by Nils Knappmeier | September 30th, 2009 @ 03:29 AM | in 1.0
When the afterChange handler submits a form via javascript, the following race-condition can occur:
1) A user clicks on one tab, the form is submitted.
2) The user clicks on another tab while the reload is in
progress.
When clicking the second link, Firefox will notice, that the URL
of the window has changed, but a link to local anchor is clicked.
In order to follow the link to the local anchor, it performs a
reload of the page before the form submit.
No form data is submitted in this case.
The fix is to remove the href from the tab-links after the control has been initialized. A patch is attached.
