Subject [jira] [Updated] (CB-1146) Application exits if back button is pressed after a soft keyboard hide.
Date Fri, 27 Jul 2012 08:29:33 GMT

     [ https://issues.apache.org/jira/browse/CB-1146?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ajit Aranha updated CB-1146:
----------------------------

    Description: 
The back button normally cause CordovaWebView.onKeyUp to be called which typically either
dispatches the event to javascript or calls backHistory().

However if the softkeyboard is displayed and then hidden, and the android back  button is
then pressed onKeyUp is never called, and the application exits instead.
 (In this case i click on a html text input and either click on the page or press android
back button to hide the keyboard.Then i press the android back button to go to the previous
page.)

-----------EDIT FOR CLARITY------------------
Just to state the obvious , the current page when i am doing the above is not the first page
in history.
If i don't show/hide the softkeyboard, the back button works perfectly and it goes back in
history.
-----------EDIT FOR CLARITY------------------
