Update Door after changing state of lever

Hello,
I am currently working on a roleplay plugin. There are doors, that can be bought. If you press on your door, a lever behind it will be activated. The lever actually updates but the door won't.
My code:

Code:

Location b1 = block.getLocation(); // block is door
Location Switch = getSwitch(b1);  // gets the lever position (succesfully)
[...]
Block targetSwitch = Switch.getBlock();
BlockState state = targetSwitch.getState();
Lever lever = (Lever) state.getData();
lever.setPowered(true);
state.setData(lever);
state.update(true);
[...]

I've tried following so far:

1. Door update
   
   Code:

   block.getState().update(true);

2. Update the block under the upper door block
3. Get the Door as door and set it to "open(true)" and then update it

Sadly, none of these tries open the door and keep it open.
(The lever opens the door if you press it ingame)

Thank you for any help

 

Take a look at this thread.

 

This does not work. No errors appear, door still does not open.

 

with block.setData((byte) someDigitHere);
you can modify the door. But there are many possible states so doing it this way works but you have to find a good way to do it. (Try it you'll see what I mean)

 

If now tried 4 days fixing this. When I try setting data nothing changes as well. Is there any other option to do this??? Or is it maybe a bug because it doesn't update with block.getState().update(true);

Nevertheless thank you very much for trying to help me

 

Take a look at this post I've made on the SpigotMC form.
