[jira] [Commented] (ISIS-2940) wrapper's call to filterIfRequired results in an empty collection being converted to null.

    [ https://issues.apache.org/jira/browse/ISIS-2940?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17471364#comment-17471364 ] 

Daniel Keir Haywood commented on ISIS-2940:
-------------------------------------------

I see also that the original return type of `List<T>` seems to become converted to a `Can<T>`.  This makes me a bit nervous - I recollect that these have (or at least used to have) different semantics.
