Hi , I extended the SPARQL grammar for ARQ 2.8.8 and used the Grammar https://jena.svn.sourceforge.net/svnroot/jena/ARQ/trunk/Grammar/sparql_11.jj. I have now realized that this grammar will not work with ARQ 2.8.9. createGroupConcat(boolean,com.hp.hpl.jena.sparql.expr.Expr,java.lang.String,com.hp.hpl.jena.sparql.expr.ExprList) in com.hp.hpl.jena.sparql.expr.aggregate.AggregatorFactory cannot be applied to (boolean,com.hp.hpl.jena.sparql.expr.Expr,java.lang.String)
Do you know wher I can find the grammar .jj file for ARQ 2.8.9. Kind Regards Max
