    I got a NPE when trying to use the "Append Streams" step in one of my own transformations, so I tried to run the "Append streams - Basic example.ktr" sample. When I try to "verify" or "preview" this sample, I get a popup indicating a NPE, with the following stacktrace in the details: java.lang.reflect.InvocationTargetException: There was an error checking the transformation: java.lang.RuntimeException: java.lang.NullPointerException at org.pentaho.di.ui.spoon.dialog.CheckTransProgressDialog$1.run(CheckTransProgressDialog.java:74) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:113) Caused by: java.lang.RuntimeException: java.lang.NullPointerException at org.pentaho.di.trans.TransMeta.checkSteps(TransMeta.java:4222) at org.pentaho.di.ui.spoon.dialog.CheckTransProgressDialog$1.run(CheckTransProgressDialog.java:70) ... 1 more Caused by: java.lang.NullPointerException at org.pentaho.di.core.row.RowMeta.mergeRowMeta(RowMeta.java:397) at org.pentaho.di.trans.steps.append.AppendMeta.getFields(AppendMeta.java:240) at org.pentaho.di.trans.TransMeta.getThisStepFields(TransMeta.java:1883) at org.pentaho.di.trans.TransMeta.getStepFields(TransMeta.java:1728) at org.pentaho.di.trans.TransMeta.getPrevStepFields(TransMeta.java:1786) at org.pentaho.di.trans.TransMeta.getPrevStepFields(TransMeta.java:1758) at org.pentaho.di.trans.TransMeta.checkSteps(TransMeta.java:4037) ... 2 more I tried this in 4.0.0-M3 and 4.0.0-M4. I also downloaded the current pdi-ce-TRUNK-SNAPSHOT.zip from Hudson (february 2 2009), and I get this exception too when I try to "verify" the transformation. Running the transformation generates other errors which might not be related to this exception. Running the sample works in 3.2.0-stable. Best regards, - Etienne Neveu
