Uff! Es war gar nicht so einfach, das Feature “Specify quantities as durations (hh:mm) or fractions (x/y)” zu implementieren. Checkin.

TODO:

• Nullable CharField qty in <class ‘lino.modlib.trading.models.OrderItem’>

• Typing “750” in a qty field whose default format is Duration should convert to 7:50

• Entering “6,5” causes an Internal Server Error “Invalid literal for Decimal: u’6,5’”

• GridPanel.on_afteredit) should not refresh the whole grid on each celledit
