JaxenXmlDataSource in iReport

[marip]

Hi! I am evaluating jasperreports and struggling with xml data source. I want to use jaxen because xalan library causes some trouble in my app's xml handling.

• I have defined XML file datasource. See attached xml.
• Tools -> Options -> JasperReports Properties has default line for  net.sf.jasperreports.xpath.executer.factory = net.sf.jasperreports.engine.util.xml.JaxenXPathExecuterFactory
• Then I have a sub data set in my template. See attached xml. It builds allright but preview causes an error when evaluating expression: net.sf.jasperreports.engine.data.JaxenXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("//row"). Preview works if I cast to JRXmlDataSource instead. See error stack attached.

Is there a problem in xml file data source or in jasperreports properties?

I am not sure what happened but JaxenXMLDataSource was working correct after the weekend / reboot. Case resolved for now.
