Subject [jira] [Updated] (CB-11394) backbutton eventlistener should be able to let cordova execute the default native behaviour
Date Mon, 17 Oct 2016 16:38:58 GMT

     [ https://issues.apache.org/jira/browse/CB-11394?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joe Bowser updated CB-11394:
----------------------------
    Priority: Minor  (was: Major)

Making this a minor issue, since the current behaviour is documented.  I do not see an easy
way to change this, and make it actually work predictably, since the default behaviour of
the back button is to close the document or the application.

> When we override the "backbutton" with a custom handler, cordova completly skips handling
of the native behaviour (as written in the docs).
> It does this even though the events `defaultPrevented` property is set to `false`. A
proper implementation of event handling would look into this property  and act accordingly.
> Not sure how this could be introduced now without breaking old code.
> Probably old code never returns a value from the event handler. So a patch could check
if the return value is `===true` then it should perform the default native behaviour of that
button.
