[OpenMap Users] Open Map Error: Anonymous|LayerWorker.construct(): java.lang.NullPointerException

I get the following message when one particular layer from my data set is drawn. The other layers from my dataset are fine, just this one. Any idea what it means?

*** ERROR ***
Anonymous|LayerWorker.construct(): java.lang.NullPointerException
        at com.bbn.openmap.layer.shape.ESRIPolygonRecord.addOMGeometry(ESRIPolygonRecord.java:211)
        at com.bbn.openmap.layer.shape.ShapeLayer2.RecordList(ShapeLayer2.java:94)
        at com.bbn.openmap.layer.shape.ShapeLayer2.prepare(ShapeLayer2.java:172)
        at com.bbn.openmap.layer.policy.StandardRenderPolicy.prepare(StandardRenderPolicy.java:67)
        at com.bbn.openmap.layer.OMGraphicHandlerLayer$LayerWorker.construct(OMGraphicHandlerLayer.java:648)
        at com.bbn.openmap.util.SwingWorker$2.run(SwingWorker.java:117)
        at java.lang.Thread.run(Unknown Source)

The same data files can be used in ArcExplorer and another map program I have used to display the data, so I am reasonably confident that the data files are ok.

Any assistance greatly appreciated,

Best Regards,
