    This NPE makes it very hard to know exactly what is wrong in my Transformation: java.lang.NullPointerException at org.pentaho.di.trans.steps.mapping.MappingMeta.loadMappingMeta(MappingMeta.java:624) at org.pentaho.di.trans.steps.mapping.MappingMeta.getFields(MappingMeta.java:383) at org.pentaho.di.trans.TransMeta.getThisStepFields(TransMeta.java:1898) at org.pentaho.di.trans.TransMeta.getStepFields(TransMeta.java:1753) at org.pentaho.di.trans.TransMeta.getPrevStepFields(TransMeta.java:1811) at org.pentaho.di.trans.TransMeta.getPrevStepFields(TransMeta.java:1783) at org.pentaho.di.trans.TransMeta.getPrevStepFields(TransMeta.java:1771) at org.pentaho.di.ui.trans.steps.selectvalues.SelectValuesDialog.get(SelectValuesDialog.java:710) at org.pentaho.di.ui.trans.steps.selectvalues.SelectValuesDialog.access$100(SelectValuesDialog.java:79) at org.pentaho.di.ui.trans.steps.selectvalues.SelectValuesDialog$2.handleEvent(SelectValuesDialog.java:154) at org.eclipse.swt.widgets.EventTable.sendEvent(Unknown Source) at org.eclipse.swt.widgets.Widget.sendEvent(Unknown Source) at org.eclipse.swt.widgets.Display.runDeferredEvents(Unknown Source) at org.eclipse.swt.widgets.Display.readAndDispatch(Unknown Source) at org.pentaho.di.ui.spoon.Spoon.readAndDispatch(Spoon.java:1169) at org.pentaho.di.ui.spoon.Spoon.start(Spoon.java:6943) at org.pentaho.di.ui.spoon.Spoon.main(Spoon.java:553) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.pentaho.commons.launcher.Launcher.main(Launcher.java:134) Is there something wrong in my Transformation setup that is causing some of the parameters for this method to be NULL ? public synchronized static final TransMeta loadMappingMeta(MappingMeta mappingMeta, Repository rep, VariableSpace space) throws KettleException { ... } If this is an error on my side, it would be nice to get some message or hint of what configuration is missing in the requirements of getting the fields from a Mapping step.
