Array Delete Index bug #4815

Closed dop2000 closed 3 years ago

dop2000 commented 3 years ago

Problem description

It's difficult to explain, but seems like "Array compare at" condition in OR-block may prevent a record in the array from deleting.

Attach a .c3p

Steps to reproduce

  1. Run and see the log messages.

Observed result

Record "BBB" with index 1 should be deleted from the array, but it isn't. If you remove the second condition in event 3, then it works correctly.

This is just the same old OR block picking which seems to trip everyone up.

The array does not meet the second condition of the OR block, so the event runs with zero Array instances picked. Therefore the action on the Array object has no effect.

This is so messed up.. I knew about this issue with OR blocks, and yet I spent 2 hours trying to figure out why the code doesn't work.. I didn't realize that "Array Compare At" condition picks array instances!
