The > problem is that depending on the execution context of the traversal, the > result could be quite different, with or without properties. > Solution: Implement new finalization strategy DetachStrategy(detachMode, > properties) where mode is one of ALL, NONE or CUSTOM. `properties` is list of > properties name, are taken into account only for CUSTOM mode. > Discussion thread in dev list: [Proposal to handle properties on response > Elements-Apache Mail > Archives|https://lists.apache.org/thread/l8rw7ydj7kym8vhtwk50nhbp45ng9986] > Stephen's thread in dev list: [The Issue of Detachment-Apache Mail > Archives|https://lists.apache.org/thread/xltcon4zxnwq4fyw2r2126syyrqm8spy] -- This message was sent by Atlassian Jira (v8.20.10#820010)
