Subject [jira] [Commented] (CAY-1975) Unexpected null value when prefetching with Cayenne.objectForQuery
Date Sat, 13 Dec 2014 08:49:13 GMT

    [ https://issues.apache.org/jira/browse/CAY-1975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14245256#comment-14245256

jotpe commented on CAY-1975:
----------------------------

No, I didn't read this, only the 3.1 documentation. 

Of course my example is very simple. In that case, your are right, SelectQuery is a better
choice.
I found this issue, while doing a select-mix between persistent object and some aggregate
values, and I wanted to eleminate the lazy loading.

Thanks for your link! Johannes

> Querying a select query with addPrefetch over Cayenne.objectForQuery results in receiving
null values for these prefetches. Without addPrefetch, the relations are loaded correctly.
