@param expression a string in the form of 'condition = value' or 'groupBy condition' @return a reference to itself, so that method chaining can be used @throws org.rhq.core.domain.resource.group.InvalidExpressionException if the expression can not be parsed for any reason, the message will try toget the details as to the parse failure
