Classification is running into an error for complex source elements with values on top level

[JohannaOtt]

When the source element for a classification function is a complex element which has a value, the classification fails with the following error message: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type eu.esdihumboldt.hale.common.instance.orient.storage.DatabaseHandle$InstanceHandle to type java.lang.String at org.springframework.core.convert.support.GenericConversionService.handleConverterNotFound(GenericConversionService.java:475) at org.springframework.core.convert.support.GenericConversionService.convert(GenericConversionService.java:175) at org.springframework.core.convert.support.GenericConversionService.convert(GenericConversionService.java:154) at eu.esdihumboldt.hale.common.align.transformation.function.impl.PropertyValueImpl.getValueAs(PropertyValueImpl.java:77) at eu.esdihumboldt.cst.functions.core.ClassificationMapping.evaluate(ClassificationMapping.java:51) at eu.esdihumboldt.hale.common.align.transformation.function.impl.AbstractSingleTargetPropertyTransformation.evaluate(AbstractSingleTargetPropertyTransformation.java:57) at eu.esdihumboldt.hale.common.align.transformation.function.impl.AbstractPropertyTransformation.execute(AbstractPropertyTransformation.java:102) at eu.esdihumboldt.cst.internal.FunctionExecutor.executeTransformation(FunctionExecutor.java:224) at eu.esdihumboldt.cst.internal.FunctionExecutor.processValid(FunctionExecutor.java:133) at eu.esdihumboldt.hale.common.align.model.transformation.tree.visitor.CellNodeValidator.visit(CellNodeValidator.java:110) at eu.esdihumboldt.hale.common.align.model.transformation.tree.impl.CellNodeImpl.accept(CellNodeImpl.java:103) at eu.esdihumboldt.hale.common.align.model.transformation.tree.impl.TargetNodeImpl.accept(TargetNodeImpl.java:177) at eu.esdihumboldt.hale.common.align.model.transformation.tree.impl.TargetNodeImpl.accept(TargetNodeImpl.java:173) at eu.esdihumboldt.hale.common.align.model.transformation.tree.impl.TransformationTreeImpl.accept(TransformationTreeImpl.java:129) at eu.esdihumboldt.cst.internal.TreePropertyTransformer$2.lambda$0(TreePropertyTransformer.java:224) at eu.esdihumboldt.hale.common.core.report.SimpleLogContext.withLog(SimpleLogContext.java:112) at eu.esdihumboldt.cst.internal.TreePropertyTransformer$2.run(TreePropertyTransformer.java:181) at eu.esdihumboldt.cst.internal.TreePropertyTransformer.publish(TreePropertyTransformer.java:264) at eu.esdihumboldt.cst.functions.core.Retype.execute(Retype.java:71) at eu.esdihumboldt.cst.ConceptualSchemaTransformer.doTypeTransformation(ConceptualSchemaTransformer.java:327) at eu.esdihumboldt.cst.ConceptualSchemaTransformer.transform(ConceptualSchemaTransformer.java:155) at eu.esdihumboldt.hale.ui.service.instance.internal.orient.OrientInstanceService$5.run(OrientInstanceService.java:473) at eu.esdihumboldt.hale.ui.util.io.ThreadProgressMonitor$1.run(ThreadProgressMonitor.java:122) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:122)

There is a halez file attached with a minimal example dataset for which this error occurs. ClassificationTypeIssue.zip

The element for which the error occurs (SO_Plan.planArt uses the type gml:CodeType.

The behavior is the same for 4.0.0 release and 4.1.0 release.

Same underlying issue as in #1025, is not reproducible any longer with latest master build.
