Description

STR:
1. On 26+ nodes cluster go to Hosts -> All Hosts
2. Add any component to all hosts:
3. Obverse this error from UI:

app.js:23508 Uncaught TypeError: Cannot read property 'get' of undefined
    at app.js:23508
    at Array.forEach (<anonymous>)
    at Class._getComponentsFromServerForHostComponentsAddCallback (app.js:23507)

    at done (vendor.js:8178)
    at XMLHttpRequest.callback (vendor.js:8702)

As per discussion with UI guys. This is because model is only available for first 25 hosts, and so for others it's not possible to check if heartbeat is not lost.

Possibly the solution could be as simple as UI asking heartbeat state in scope of the request along with other info.
