prepareCall fails with nested procedure calls: group function is nested exception: group function is nested

Hi all,

I am trying to call a procedure from xsjs script in this way:

conn.prepareCall("{call  OutliersInSplitByOneDimension('"+currentDimension+"', '"+currentMeasure+"', '"+currentFilters+"')}");

but I am getting an error saying :

group function is nested exception: group function is nested:

It seems like prepareCall cannot prepare procedures with nested calls, is this true? If yes what to do about it, I mean

how to call this procedure?

Thanks & regards
