Yeah, I have only seen examples of contains() used with the field name
first and then a single value. That could becomes a normal mulit-
valued property query. But Im guessing that somewhere your query
would have to be converted into an IN query to work.

Here is the reworked query for posterity:
def getComments() {
List comments
List results
if (this.comments.isEmpty()) {
return this.comments
}
PersistenceManager pm = PMF.get().getPersistenceManager()
try {
javax.jdo.Query q = pm.newQuery("select from " +
Comment.class.getName() +
" where hos
Nevermind, I think I got this. Thanks all.

Sorry to have to ask, But can you hint as to how I should rewrite this query
so as to have cursors working?

Thank you John, I wasn't clear IN was contains() as well.

Cursors are not supported for queries that use IN (contains) because
under the covers they are broken into multiple queries and merged
together.

What do you mean by every query result greater than 1? Do you mean

I'm trying to get cursors working with a result set but the
JDOCursorHelper.getCursor() method returns null for every query result that
is greater than 1
here is my entity method
Item entity:
@Element(dependent = "true")
@Persistent(defaultFetchGroup="true",loadFetchGroup="true")
List com
