Blank screen when loading my app on the Q10 / Dev alpha C

[bglowDragosh]

My WebWorks app (it uses bbUI) does not load up properly on the Q10 VMware emulator, nor on the Dev Alpha C device:

• on the emulator: after several attempts of loading it on the VMWare Q10 simulator, when it finally does load, I just get a blank black screen.
• on the dev alpha C device: I got a blank white screen when I tried loading it on the device.

Note: my app loads and runs with no issues on the Dev Alpha A/B, PlayBook and Z10 devices, the dev Alpha A/B VMWare emulator, and both Z10 & Q10 emulators in Ripple.

Anyone else getting this issue? What could I be doing wrong?
PS : I also checked the console log in Ripple for bugs and I could not find any.

There are on device components. Can you list which OS versions where the app is working?

[bglowDragosh]

Thank you for your prompt reply. These are the versions:

• PlayBook OS: 2.1.0.1314
• Dev Alpha A/B VMware emulator: BB10_0_09-2318
• Ripple version: 0.9.13
• cannot check the OS versions for the Dev Alpha A/B and Z10 devices at this time (it was tested by someone else for me).

@bglowDragosh
Is it really necesarry to report the issue on two different repositories at the same time?
blackberry/bbUI.js#684

Have you updated your WebWorks Framework?
https://developer.blackberry.com/html5/downloads/fetch/BB10-WebWorks-SDK_1.0.4.7.zip

Have you tried the Dev Alpha C Simulator to see if the problem occures in the simulator?

• since this may either be a bbUI issue or a WebWorks issue, I found it appropriate to post it on both repositories. Sorry if that disturbed you, I will close both issues with the solution anyway, once they are resolved.
• my WebWorks framework and bbUI versions are up to date.
• as I've mentioned - the Q10/Dev Alpha C VMware emulator and the Dev Alpha C device is where my app does not load. Thanks for your help.

What is the OS version of the Q10 emulator?

[jeffheifetz]

Also just to narrow it down, does it load up if you remove the bb-ui resources?

[bglowDragosh]

The Q10 emulator's version is 10.1.0.338.
I've just tried completely removing bbUI from the app, and it loaded (on the Q10 VMware emulator).

[jeffheifetz]

Then I will close this issue since for now it clearly seems bbUI related. If it comes back to being a framework issue at the root we can re-open.

[bglowDragosh]

Very well, thank you very much for your help!

Thought I'd post the solution here too.

Turns out, this old code snippet in my index.htm file was preventing my app from loading up on the Q10:
