m.f. (4/26/2016)
yes, changes have been deployed an processed.At the Moment, it seems to me, that the KeyColumn also must be of the datatype date, like the ValueColumn.
After these changes it works.
But i want to leave my KeyColumn as an integer, if it is possible.
The Key can be of datatype integer, but the ValuColumn from the KeyAttribut must also be from a column with Datatype Date.
No it works!
Thx!
