Account management - after modifying user, cannot edit a second time

[davroth]

1. omnistaging.azurewebsites.net/emp, chrome 43, windows 8.1
2. click edit button adjacent to Account Name, select Users tab
3. edit an existing user by clicking on that row - I clicked on the name and changed name from David to Juliet
4. click update user and row is updated
5. click on Juliet (the new name)

Actual - row contents are cleared

Expected - to be able to edit the newly changed name

Note - this is a UI issue; the row is still there and is displayed and editable after closing the Account Management dialog and then re-opening
