Hi everybody, Can someone please help me ? I'm using JasperAnalysis 3.7.0. running under Windows XP. I can load the foodmart.xml demo shema in JasperAnalysis, and I can open an MDX query window, with a "Mondrain Connection Successfull" message. However when I want to generate the mdx by clicking at the MDX button, i got this message in the mondrian log window : Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at org.olap4j.mdx.AxisNode.deepCopy(AxisNode.java:166) at org.olap4j.mdx.SelectNode.deepCopy(SelectNode.java:238) at mondrian.gui.MdxQuery.generateMDXMenuItemActionPerformed(MdxQuery.jav a:560) at mondrian.gui.MdxQuery.access$300(MdxQuery.java:91) at mondrian.gui.MdxQuery$4.actionPerformed(MdxQuery.java:274) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Sour ce) at java.awt.AWTEventMulticaster.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Post Edited by mespub at 02/18/2010 15:02
