A closer look at the code, id the get / set methods written so there's no error, I have no more to see, then looking for a long error, blame themselves more than negligence, which later led to the paging query fails, look at this record, property writing as consistent as possible, otherwise it is not being given, you may not check, you will encounter problems such as the failure of the query or injected.
