The point is that I don’t want to have to work out the class of the entity in
advance, by looking at labels and so on. The method
neo4jTemplate.createEntityFromStoredType(node, null) is supposed to do that,
but it doesn’t work for me unless I’ve previously tickled it by using:
myDomainClasses.each {
neo4jTemplate.getMappingPolicy(it)
}
:(
I haven’t managed to work out how to get the SDN source bound to my project, so
I’ve not been able to step into the code to work out what’s going wrong.
