The Java RIA Framework

Vincent,

When I start my application I get a NPE, see below, with this instruction (in CheckStartup.doIt):

        List<Payslip> payslips = getHibernateTemplate(context).find("from Payslip");

The value of the argument "propertyName" sent to AbstractComponentDescriptor.getPropertyDescriptor is "_org.popsuite.hr.model.Contract.payslipsIndexBackref".

Indeed there is no such property name in the model (or in view and frontend configuration files). I put Contract model below.

Regards

Pierre
