I upgraded my development gateway to v7.9.14. Everything was working fine while adding a couple of users with the management component. After adding a user an error popped up and the list of users went blank.

Turns out this error is coming from the `filterRole` extension function. If I disable it, the component works fine. Otherwise, I get a null pointer error. Below is the filtering script that worked perfectly before

```auto
userRoles = user.getRoles() 
for role in userRoles:
	if 'operators' in role:
		return 1
	else:
		return 0

```

Steps to remedy error

1. Downgrade to 7.9.13 -\> no change
2. Downgrade to 7.9.12 -\> no change
3. Import project backup from 7.9.12 production server to 7.9.12 dev server -\> no change
4. Install production gateway backup into dev server -\> null pointer fixed
5. upgrade dev server to 7.9.14 -\> no issues yet, but this is the version that the error originally occurred

Turns out the null pointer is coming from saving a user without a role selected. Once this happens, I have to go to the gateway page and add a role to the user for the component to start working again. I do have a filter role extension function running, however once I added the user role and comment out the filter role script the null pointer error pops up again.
