String data is automatically converted to Date

Hi,

In the Gantt chart data source, strings sometimes automatically convert to dates. Is there a way to prevent this conversion?

As shown in the sample code, when values like ‘001’ or ‘002’ are set, the grid cell displays “Mon Jan 01 2001...”.

Ideally, ‘001’ and ‘002’ should be displayed as-is.

Setting the type property in ColumnDirective had no effect.
