Web Staff Client - Sign in screen workstation dropdown loads slowly

[Terran McCanna]

On the login screen in the 2.11 web client:

The Username and Password fields load immediately, but the Workstation dropdown list does not load for 3 or 4 seconds. If the staff person begins typing in the username and password too soon, whatever they've typed in is cleared out when the workstation list loads, and has to be retyped.

I'm not sure of the best resolution - perhaps the Username & Password fields could be hidden until the Workstation list is available?

I have noticed this in testing as well. Entering the username and password, then seeing it blanked each time they login can be a source of frustration for staff users.

Rather than hiding the Username and Password fields until the workstation loads, perhaps keeping them visible, but disabling text entry until the workstation choices load would be an option?

Hiding the fields may give the impression that the login screen takes longer to load than it actually does.

When this happens, does it look like the page is reloading while entering values in the form? Similarly, does it happen during the second login if you login, logout, then immediately log back in?

Yes

Yes

Hmm, I would answer the first question as No. I don't see any indication that the page is still loading.

[Terran McCanna (tmccanna)]

It looks like the page is completely loaded at first when I begin typing, but then looks like it reloads the entire page when I'm partway through.

I did a quick screencast of reloading the login page a few times. This is in Chrome, and for testing purposes, the username and password is remembered by the browser. Note that as the workstation info fills in, the username is blanked:

Thanks for the screencast, Michele. I was finally able to reproduce this in Windows. (I don't see it on Linux or Mac). What I see in the logs is a brief pause before the XMLHttpRequest to Hatch finally fails. This step in the page load process is completely different in the new Hatch code, so there's a chance bug #1646166 will resolve this. I'll try to confirm today (unless someone beats me to it).

Confirmed bug #1646166 resolves the issue for me.

I recreated on a Win 10 machine talking to a local VM running master, issue occurred. Installed Hatch branch on VM with Hatch disabled in the browser, issue did not occur. Enabled Hatch, issue still did not occur.

I'll leave the bug as is until others confirm.

I can confirm that the slow-loading of the workstation selector does NOT occur on Kathy Lussier's MassLNC server that's running the Hatch branch.

Thanks, Michele. Marking this as a duplicate of bug #1646166 so we can track when the fix is released.
