Make setErrorText display the original data instead of a fixed text

Hello,

When using AW.Formats.Date, setErrorText can be used to display a fallback text when data can not be converted into date.

Is there a way to display the original value and not a fixed text when a conversion error occurs?

I tried

myGrid.setErrorText(function(arg1,arg2,arg3){...})

but there seems to be no useful information to retrieve the original value (which is set by setCellData) for the cell beeing converted/formatted (like row number)?
