TypeError in ValidationService.OIDValidator, UI lockup

[jamesboswell]

What:

Reset form action in SNMP metrics form throws a TypeError. Second reset of form locks up the entire UI. All buttons and left side menu become unresponsive.

Version

SNMPCollector - 0.5.3 - ff26b4b (Nov 7, 2016)

Steps to reproduce:

1. Login
2. Select SNMP metrics
3. Select Add metric
4. Select DataSrcType Integer (any of them really)
5. Click Reset (at this point you will get error below)
6. Fill in the form again
7. Click Reset again (now the entire UI will lockup including left-side menu)
