I have confirmed that the second callback behaves the same way and internal fields are still NULL pointers. I reset the global handle in the first callback and then after the script returned, I pumped the message loop and in the second callback internal fields are still NULL. So, the same two questions: 1. How can I get the two internal fields in the weak callbacks (first or second) set to the internal field values of the object for which this weak callback is being called? 2. In order to use second pass callbacks I need to pump the message loop. In a long-running script, am I supposed to do this within object callbacks?
