 Description   

Steps to reproduce :
-Place the observer
-Place redstone dust next to it
OR
-Make a water BUD
-Place redstone dust next to it

What I expected to happen :
-The observer would output a short redstone pulse
OR
-The water BUD would trigger

What happened :
-Nothing

Removing dust works correctly.

Please respond and add the current version if you can reproduce this issue.

Maybe. Block updates don't trigger anything else than the observer AFAIK, and sadly we don't have access to the source code, so there's no way to know whether this is a bug of the observer or of the redstone dust.
Ninja edit : water can be redirected by block updates. I'm going to test.
Re ninja edit : it is a bug of redstone dust.

@Azelef: Isn't it possible that placing redstone dust simply doesn't cause a block update? Of course, that would still be a bug, but the bug would be with the redstone dust, and not the observer. I'm not sure how an Observer actually works, but if all it does is check for block updates on the observing end of the block, then most problems it has detecting certain changes would be the fault of the other blocks, rather than the Observer itself. I could be wrong, though.

MCPE-14710 seems to be about the observer not detecting changes in block data. Here the whole block changes. I think the part of the code to change for these two bugs isn't the same.

Possibly "Duplicate" of MCPE-14710
