[70231f697a2b3c2b]

Confirmed fixed in https://github.com/bitshares/bitshares-2/releases/tag/v2.0.151119.

[svk]

Running BitShares2-light client v2.0.151101 on Mac OS 10.11.1.

1. Launch BitShares.
2. Select an account.
3. Click on the Membership tab in the left nav menu.
4. Several Javascript errors occur (only detectable by Toggling DevTools):
  - Uncaught Error: argument is not an object id: undefined (app.js:50)
  - Uncaught TypeError: Cannot read property '_currentElement' of null (repeated many times) (vendors.js:17)

We've fixed this on OL already but not sure when the light client will get the update, will ask Valentine.
