Current Behavior

A ForEachChildElementPipe with IbisLocalSender and "returnedSessionKeys" configured to return the Error sessionKey, results in an empty Error sessionKey in the parent adapter, while the subadapter has a value for the Error sessionKey.

Expected Behavior

SessionKeys from subadapters listed in "returnedSessionKeys" in a ForEachChildElementPipe should be inherited in the parent adapter.

This one might be a bit interesting when the ForEachChildElementPipe is run in parallel as multiple threads may end up with a value for a certain sessionKey. Perhaps returned sessionKeys should be treated the same as the output of the ForEachChildElementPipe, where the result is wrapped in a list? Maybe the sessionKey from subadapters can use whatever wrapper(custom/default) is configured for the output of ForEachChildElementPipe
