Nodes sometimes not moving correctly

[jidel]

How to get this behaviour:

1. Enable error lines
2. move a node and wait for the updated lines and positions
3. repeat moving the node
   After some recalulcations of stress and error lines, the node jumps back to its old position. Could be an issue with scope not updating in time.

After moving each node should i wait until it is updated or should I try to do it before complete update? I couldn't reproduce any such bug when waiting for all positions to be updated.

I waited for the nodes to load and needed a few tries. As the number of tries is not fixed, I'm guessing there is some angular issue behind it (I'm guessing the mapData object in the ctrl not having the position of the moved node)

Sometimes the data we get back from the fileHandlingService is the same we pass to it:

Additionally, the projection number does not change either.

That's a weird case, good thing: finally i can reproduce it.
I can look further into it on 30-01-2016.
