I downloaded and installed iReport NB Release 3.1.3 (.exe for Windows). Afterwards I followed the simple steps on the "iReport NB - Getting Started" page. I succesfully created a JDBC connection to an Oracle database. I can browse the tables and other objects. Now I want to call the wizard or even a new empty report, but nothing happens. I get the follwing error: java.lang.IllegalArgumentException: Called DataObject.find on null at org.openide.loaders.DataObject.find(DataObject.java:474) at org.openide.loaders.DataFolder.findFolder(DataFolder.java:515) at com.jaspersoft.ireport.designer.standalone.menu.ReportWizardAction.performAction(ReportWizardAction.java:32) etc. Is there something else I have to do, like setting paths?
