What about Mapping of Lists of Complex Objects #30

Closed ghost closed 6 years ago

ghost commented 7 years ago

Hello!

When i map an Object, primitive fields will be mapped to Node properties, complex types will be mapped to other nodes and linked to the parent.

How can i map a field which is a collections of Complex Types, which means to map it to several nodes of the Type of the List and link them to the parent. Is there a possibility or a workaround, other than a bottom up approach to realize this? It doesnt work if i just put a field of Collection Type in the class of which i intend to map the object.

Thanks in advance!

Philipp

Hi Philipp,

The field should be of type java.util.List or a subtype thereof and can contain (arbitrarily) complex objects. Please try it. If it does not work, I will send a working example.

Best regards, Wolfgang
