Access mondrian via XMLA from DevExtreme Pivot

[Karel Haruda]

Hi,
I try to use mondrian as OLAP server for DevExtreme Pivot using XMLA. I got error

Mondrian Error:No function matches signature 'NonEmpty(<Set>, <Set>)'

Mondrian Error:Failed to parse query 'with set [DX_columns] as NonEmpty({[Firma].allMembers}, {[Castka]}) set [DX_rows] as NonEmpty({[Obdobi].allMembers}, {[Castka]}) SELECT CrossJoin([DX_columns],{[Castka]}) DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME, MEMBER_VALUE ON columns,[DX_rows] DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME, MEMBER_VALUE ON rows FROM [IssuedInv] CELL PROPERTIES VALUE, FORMAT_STRING, LANGUAGE, BACK_COLOR, FORE_COLOR, FONT_FLAGS'

Can somebody help me with this issue ?

Thx
Karel
