Thanks for the issue. I've actually never seen this error message before. Is the site where this happened public that I could look at? From the message my guess is that some JavaScript code is overriding native Node features as we would expect a node object to have a nodeName property.

The issue was caused by a field using nodeName as its name attribute. Changing this value resolved the problem.

Interesting. So the field looked like this and it threw the error? If so I think this would be something we might want to look out for in the future.

<form><input name="nodeName"/></form>
