("dropper" means dropper or dispenser in what follows) When redstone torches, dust, and repeaters power the block above a dropper, the dropper activates. When levers or buttons do likewise, a block update at y+1 from the dropper is necessary (but not always sufficient) for the dropper to activate. Screenshot A, B, and C show setups that, when placing the torch/dust/repeater (in the powered on state) or toggling its power on from an outside source, causes the dropper to eject an item. Screenshots D and E show a lever/button that should do likewise because they power all 6 sides of themselves, yet they do not when toggling their state. Screnshot F shows that, when the lever (button also) is on, and a block is placed/destroyed on the dropper, it sometimes ejects an item (but only one block update max to y+1 of the dropper makes the dropper eject an item without toggling the lever/button off and on again, while also possibly needing to modify the contents of the dropper). |

Same symptoms, similar cause, but fixing one won't fix the other. |

Pistons do the same thing and it's up for the developers to decide whether this behavior is intended or not. What you describe here are the symptoms of |

I don't think it's a duplicate of that bug; based on looking at the code for 1.4.7 (MCP's onNeighborBlockChange() function in BlockDispenser.java), I think droppers/dispensers activating when the block at y+1 of them is powered is intended. If that's intended, the bug is that dispensers/droppers receive power differently from levers/buttons than dust/torches/repeaters (and comparators that I just checked now). |
