How to use non-sustainable objects to customize the asynchronous data source tree

Version: Windchill 13.1

Use Case: Customize the tree by using asynchronous data transformation to implement TreeDataBuilderAsync, ComponentConfigBuilder, and ComponentConfigFactoryAware methods, and create non-persistent object beans. Add the String oid attribute and override the GetOid method.

Description:

I used non-sustainable objects to create a custom asynchronous data source TREE. When loading the child items, I found that the buildNodeData method's Object node was not the parent node object but NmSimpleOid. The parent node object was not extended but had a String oid attribute added and the getOid method was overridden. Now, I don't know how to obtain the parent node object through NmSimpleOid.
