Looking at the exported flow, there are two wires from the ui switch to the Switch. How the system could get into this state I don't know, and what is the best way to get out of it I don't know. Perhaps delete those nodes and recreate them.
I think this may need someone like @knolleary to look at it.
@Colin Yeah that's the problem, if you delete the first one the second one isn't select able until you refresh the screen then you can delete it.
i couldn't directly reproduce it after, had to copy that one over.
Phew thought it was just me lol.
I could not understand the issue for quite sometime,
There appears to be only one connection between UI Switch and Switch Node,
but when you introduce another node in between, there appears another 'hidden' wire, which you cannot 'select' but disappears when ui switch node is deleted.
@Colin. No idea just dropped a ui switch and a switch node then linked them. Had me chasing my tail for hours. Didn't drag anything in between at any point.
Done a few more tests and can't reproduce it again.
@smanjunath211 I presume you do mean that you are able to create the situation with duplicated wires, not just that you see the wire delete problem once you have duplicate wires. The wire delete problem is not a significant issue as it should not be possible to get into that situation in the first place.
hehe .. my wording was a bit confusing .. i meant it happened to me a few days ago but i didnt report it sooner because i couldnt replicate it. Now that more people saw it also i tested a bit more and managed to find a case. (edited my post on github to explain more clearly)
