Since a proper answer was not provided for a while, and what was answered by Austin was just a quote from the very ambiguous documentation, here’s a small input from my dive into the code:
List<String> toskip = Arrays.asList((membersToSkip + ",createdDate,changedDate").split(",")); List<String> tokeep = Arrays.asList((membersToKeep + ",System.owner,System.changedBy").split(","));
So, basically, you need to add a list of members from which you clone, separated by comma, without trailing space or any sort of space, really, example, a classic “Todo” entity would have ‘[Text] Body’, ‘[Boolean] Completed’ and ‘[DateTime] DateCompleted’:
members to skip: ‘Body,Completed’
That would pretty much NOT copy Body and Completed members to the new instance of the model/entity.
Just remember – comma-separated members.
Here’s a link to the GitHub: https://github.com/mendix/CommunityCommons/blob/master/src/CommunityCommons/javasource/communitycommons/ORM.java
The syntax is included in the documentation part of the java action.
members format: <membername> or <module.association> or <module.objecttype/membername>, where objecttype is the concrete type of the object being cloned.
If you have a module called MyFirstModule and an entity called Order, you would use a string like this
If you want to include everything try passing empty strings into those fields except for "members to keep". I think this one is mandatory.
