Hi,
I'm trying to pass in a collection of Strings to be used in a filter using
Objectify (which I LOVE, btw). I'm doing it like so:
Query<SNote> query = ofy.query(SNote.class).filter("id IN",
results).limit(limit).offset(offset).order("-timestamp");
where the results parameter is a non-empty ArrayList<String>.
I'm getting the exception:
64951 [btpool0-4] ERROR com.deathrayresearch -
java.lang.IllegalArgumentException: A collection of values is required.

com.google.appengine.api.datastore.DataTypeUtils.checkSupportedValue(DataTypeUtils.java:153)

com.google.appengine.api.datastore.Query$FilterPredicate.<init>(Query.java:543)
at com.google.appengine.api.datastore.Query.addFilter(Query.java:231)
at com.googlecode.objectify.impl.QueryImpl.filter(QueryImpl.java:102)
at com.googlecode.objectify.impl.QueryImpl.filter(QueryImpl.java:28)
The id parameter contains Strings and I think an ArrayList<String> qualifies
as a "collection of values". Can anyone tell me what I'm doing wrong?
thanks much
Larry
