Error when changing rows via js script

[Mocio89]

Hi,
When i try to change the rows Property inside a Unified JS script, i get this error (TraceViewer):
session: 0024, trace: PROPERTY_SET Invoke failed (property='Screen->Items->Properties->rows', id=4, error=0x80000000)

Here is my code:

Screen.Items("SelettoreRicette").Properties.rows = [["a"], ["b"], ["c"], ["d"]];

Thanks

Hi,
I'm still working on the documentation but, anywaway, in order to send data to the CWC you need to convert your array into a string with "JSON.stringify()", the "Array" data type is not supported inside CWC's
So, to display the data you will need to :
Screen.Items("SelettoreRicette").Properties.rows = JSON.stringify([["a"], ["b"], ["c"], ["d"]]);
