[android-developers] SODA query throwing exception :-com.db4o.internal.query.ObjectSetFacade

Hi ,

In one of my project i am doing SODA query in db4o, i used this code
to retrieve object of Recipe.

public List<Recipe> getRecipiesByString(String searchValue)
{
List<Recipe> list=null;
Query query=db().query();
query.constrain(Recipe.class);
Constraint constraint=
query.descend("_title").constrain(searchValue).contains();

query.descend("_description").constrain(searchValue).contains().or(constraint);

list= query.execute();
return list;
}

Where "_title" & "_description" are field of Recipe class of type
String.

it has been throwing "com.db4o.internal.query.ObjectSetFacade"
and i am getting zero size of list.
can any one sort out issue? what does it mean "ObjectSetFacade" in
db4o?

Regards
Imran ali
