foreignColumns with multiple columns validation error #526
When I try and use foreignColumns with multiple comma separated keys I get the following error.
I've spent hours trying to get this to work and then found this in the source which may be related.
Could be related to this statement in MapperBuilderAssistant.buildResultMapping
I don't have the stackctrace. The exception is thrown in ResultMapping.validate below. The bug is probably caused when the variable column is set to null in MapperBuildAssistant shown above.
