When adding a record for a specific recordstore , it's added to another recordstore also!?

Question

I have a LWUIT application that involves two RecordStores players1_recordStore and

players2_recordStore . Two methods method SearchCarded_team1 for retriving all records of

players1_recordStore, and method SearchCarded_team2 for retriving all records of

players2_recordStore . 4 Buttons b1 for adding new record to players1_recordStore,b2 for adding new

record to players2_recordStore , b3 to retrieve all records of players1_recordStore and b4 to

retrieve all records of players2_recordStore.

I have a couple of problem in my application

1- When b3 Button or b4 pressed the first record is not displayed!

2- Why the records of players2_recordStore are displayed beside records of players1_recordStore

when pressing b3 Button and the opposite is true.

Answer 1

The openRecordStore() method's first paramenter is the RecordStore name. You are opening the same RecordStore twice; "My Record Store". If you want them to be 2 different record stores, then you need to give them two different names.
