title: Core data prefilling sqlite db. What is Z_MAX?
body: <p>I am using the SQLite Manager extension to Firefox to prefill my core data sqlite database.</p>
  
  <p>But when i try adding more to the prefilled database my app crashes. I suspect it has something to do with Z_MAX for my entity in the table Z_PRIMARYKEY.</p>
  
  <p>What should i set Z_MAX to? Is it supposed to be the number of items in my entity?</p>
  
  <p>So if i add 1000 entries in the table Z_MYENTITY then i have to set Z_MAX to the correspoding entity in Z_PRIMARYKEY to 1000?</p>
