I tried just my Copier but still get: Could not find a transformer that can transform objects of null to objects of (class java.lang.String) net.sf.morph.transform.TransformationException: Could not find a transformer that can transform objects of null to objects of (class java.lang.String) at net.sf.morph.transform.transformers.SimpleDelegatingTransformer.getTransformer(SimpleDelegatingTransformer.java:523) at net.sf.morph.transform.transformers.SimpleDelegatingTransformer.getTransformer(SimpleDelegatingTransformer.java:435) at net.sf.morph.transform.transformers.SimpleDelegatingTransformer.getTransformer(SimpleDelegatingTransformer.java:472) at net.sf.morph.transform.transformers.SimpleDelegatingTransformer.convertImpl(SimpleDelegatingTransformer.java:293) at net.sf.morph.transform.transformers.BaseTransformer.convert(BaseTransformer.java:368) at net.sf.morph.util.TransformerUtils.transform(TransformerUtils.java:168) at net.sf.morph.transform.copiers.BasePropertyNameCopier.copyProperty(BasePropertyNameCopier.java:160) at net.sf.morph.transform.copiers.PropertyNameMappingCopier.copyImpl(PropertyNameMappingCopier.java:138) at net.sf.morph.transform.transformers.BaseTransformer.copy(BaseTransformer.java:504) at net.sf.morph.transform.transformers.BaseTransformer.copy(BaseTransformer.java:470) at com.comcast.uivr.divr.routing.CallTransferController.convertCallSession(CallTransferController.groovy:603) at com.comcast.uivr.divr.routing.CallTransferController$convertCallSession.call(Unknown Source) at com.comcast.uivr.divr.routing.CallTransferControllerTests.testSmokeTestCallSessionValueAssignment(CallTransferControllerTests.groovy:21) at junit.framework.Test$run.call(Unknown Source) at junit.framework.Test$run.call(Unknown Source) * * * * --- Thank You… Mick Knutson, President BASE Logic, Inc.
