Robospice. How to save data and how to get data from DB?

Question

In project i use Robispice and have an issue. I try to send request

getServiceManager().execute(
new GetMessagesRequest(), "ChatItem", DurationInMillis.ONE_MINUTE, new GetMessagesResponseListener());

but in GetMessagesResponseListener has no event happends.

The request below works correctly.

 getServiceManager().execute(
 new GetMessagesRequest(), new GetMessagesResponseListener());

Also when i try to get data from DB using

getServiceManager().getFromCache(...);

Nothing happends.What is my problem?
