some times a link or a node does not get the label and it wont display information

Some times a link or a node does not have "the label" and it wont display information, the popup that displays from below doesn't show up.
After some refresh (F5) all links and nodes get the info and everything works

After some minutes the app stops responding the problem seems to be something similar, a link without label

Links that are in the reference state should have a label maybe indicating type and "in reference".

This is bug that happen when an exception is thrown during the render of the node, usually related to an undefined or whatever. Lets see if i can reproduce it
