Subject:    Re: Accessing a C++ dataengine from a QML plasmoid

I am really thinking that something in my dataengine prevents my QML plasmoid from \
accessing the data. For example, my C++ plasmoid correctly displays the 3 lines it is \
supposed to, when the QML version does not display anything.

I tried to dig more the issue, and discovered that banksModel.count returns 1, \
instead of 3... Is there anything special that needs to be done in a dataengine in \
order that a QML plasmoid can access its data ?
