--------------------------------

             Summary: Cordova crashes with UIPopoverPresentationController exception in web
forms
                 Key: CB-7694
                 URL: https://issues.apache.org/jira/browse/CB-7694
             Project: Apache Cordova
          Issue Type: Bug
          Components: iOS
    Affects Versions: 3.6.0
         Environment: iOS 8.0.2, xCode 6.0.1
            Reporter: Alex Ivaylov


I have this issue on both Cordova 3.5 and 3.6.

I have a web form that uses jQuery mobile. It is a mixture of text fields, selects and a date
field (the www folder is attached below).

The app randomly crashes when moving between the controls and I can not figure out how to
replicate the bug. I just go around all the controls and in a random moment I get the exception
shown below.
