PDO lastInsertId() always return 0

Question

I\'ve come across with a problem. My framework was working just fine with PHP 5.3.0. I upgraded my PHP version to PHP 5.4.x and I started to have few issues with some parts

Answer 1

When no exception is thrown, lastInsertId returns 0. However, if lastInsertId is called before calling commit, the right id is returned.
