> During the Deploy phase of the Add Hosts Wizard, I hit the X on the top-right
> corner. This showed a Hosts table with strange data (no hostnames, etc - see
> screenshot).
> After this, I launched Add Hosts wizard after some time (after the install
> tasks were done, I believe).
> Now, the wizard tries to continue from the Review step and gets stuck.
> Refreshing the page, logging out, etc, doesn't help.
> At this point, the user needs to go back to Step 1 of the wizard from the
> left nav to clear out this weird state.
> * We should add a way to Abort the wizard with a confirmation, so that it
> doesn't get stuck (to clear the "persist" state and launch the wizard from
> Step 1 with no artifacts from the previous run).
> * We can force page refresh upon closing the wizard to prevent the broken
> hosts table problem.
