Uncaught TypeError: Cannot read property 'id' of null

[leedongwei]

Steps to reproduce

This is a weird issue to reproduce as it appears on staging/production build only. I can't tell if it's Webpack that's creating the problem, or it appears due to latency between client/server.

Stacktrace points to this line of code that's causing issues. It may be a similar issue to #111.

To cause the error, I create then delete a document. I am working around it by setting listStrategy: always. Sorry for the scant report, I'll update when I have more info.

Expected behavior

No errors

Actual behavior

The issue I reported in #111 has actually come back for me so I've don't think it's been completely fixed. It's a bit confusing as it's not happening all the time. For example I have 2 places where I'm creating documents using the same code the only difference being the data submitted and the service being called.
