BlockUpdate dont work on flowers?

Hi,
i want to make a flower, on top of a clay block...
to do this, i disabled all kinds of block updates:

Code:java

  @EventHandler
  public void onBlockPhysics(BlockPhysicsEvent e) {
    e.setCancelled(true);
  }
  @EventHandler
  public void onBlockRedstone(BlockRedstoneEvent e) {
    e.setNewCurrent(0);
  }
  @EventHandler
  public void onLeavesDecay(LeavesDecayEvent e) {
    e.setCancelled(true);
  }

but... if i place a flower on top of dirt, and replace the dirt with worldedit, the flower breaks after 2 minutes... i dont deastroy a block near the flower, but this is the result after 2 minutes:



have someone an idea how I get it flower there?

Thank you

In minecraft you can't do that from what I'm aware of. Changing block physics, redstone and leaf decay is not going to allow you to do this.

I think it's impossible man.
