newVm crash and null pointer exception sample test case project #1298

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Please clearly state whether the issue relates to a device/the simulator or
the tools.
Device iOS
If related to a device be sure to specify exactly which device with as much
details as possible.
iPhone 4, iOS ver 7.1.2

What steps will reproduce the problem?
1. Run the sample project and on the main screen first press checkTime
2. after that press nextForm button
3. In the next Form enter some pin value and some amount value and press submit
4. And press Back button.
5. Play around with nextForm and back button for 2 to 3 times

What is the expected output? What do you see instead?

The app should run without causing any crash or null pointer exception.

We see the null pointer exception when the app is started the first time and 
you enter the nextForm and enter some pin value and then enter some amount 
value. Also after some time the app will crash when you perform this a few 
times.

What version of the product are you using? On what operating system?

Latest cn1 newVM build server.

Please provide any additional information below.

The sample project with source code and resource file is attached. Please note 
the null pointer exception comes some time and not always. Here is the stack 
trace from it:

Another observation is that, when we click from pin field to the amount 
field(which is a decimal field), sometimes the decimal keyboard is shown and 
then it gets replaced by the only numeric keyboard(without the decimal point 
'.')

After fixing issue 1278, I can't reproduce this issue on the new VM.  Fix will 
be available in next update.

Has the new code updated on build server?

With the latest build, the sample project is still giving null pointer 
exception as given in the stack trace below:

No it hasn't.   I'm not sure what Shai's schedule is for updating it.  It may 
be a few days.

Thanks Steve for the update. Any way to check the build server version, so that 
we can know when new changes are applied to it? If not, would you please 
announce on the discussion thread, so that I can verify the fix.
