[Qt-qml] Trivial issue I'm sure

[mathias.malmqvist at nokia.com]

Thanks Michael, but I resolved the issue. 
As someone else already suggested, rather than

property Margins margins
margins: { left: 10; right; 10; top: 6; bottom: 6 }

the correct syntax is

property Margins margins: Margins { left: 10; right; 10; top: 6; bottom: 6 }

Don't know why is still didn't seem to work with this syntax at first, but it 
does now. So the issue was indeed quite trivial.

Thanks!


Cheers
Mathias

Any chance you can share the C++ code for this? (that should make it much easier to identify the culprit)

Thanks,
Michael
