| Issue |
We are using PhAB, and have several callbacks. How can we specify the order that they are executed in if they are all called at the same time?
|
| Solution |
In the callback list within PhAB, list your callbacks in order of execution. i.e. The first callback on the list will be executed first.
If you return Pt_END from one of these callbacks, the chain of execution of the callbacks will end.
