Cannot read property 'currentStyle' of null

[jirmed]

If I use a databinding for the property titleText to the main JSON model defined in manifest.json (in my case {/name}) the title is displayed correctly but following error is in the console:

Uncaught TypeError: Cannot read property 'currentStyle' of null
