> Key: UNOMI-1046
> URL: https://issues.apache.org/jira/browse/UNOMI-1046
> Project: Apache Unomi
> Issue Type: Sub-task
> Components: unomi-tracker
> Reporter: Serge Huber
> Assignee: Serge Huber
> Priority: Major
> Fix For: unomi-tracker-1.6.0, unomi-tracker-2.0.0
>
>
> On a button or other element that does not leave the page, whose clicks are
> sent with sendClickEvent, the site's own click handlers ran twice for each
> click: a toggle switched back, a counter counted double, a menu opened and
> closed.
> Cause: once the event was sent, the tracker dispatched the click again on the
> element, and that copy reached all the page's listeners.
> Fix: clicks on elements that do not leave the page are no longer held back
> nor dispatched again; the event is just sent. Clicks on links and submit
> buttons are still held back until the event is sent, then dispatched again to
> the whole page as before, so that routers of single-page applications handle
> them. Covered by browser tests against each Unomi server.
