Device Registration view will not load

Troubleshooting tips for when the Device Registration view will not load.

Cause

The typical cause of this registration problem is a corrupted cloudSentienceConnector-ux module. This is evidenced by the “White Screen of Delay” seen after double-clicking the CloudConnector. This persistent blank view indicates that the Device Registration widget did not load.

Tips

First, wait about 10-15 seconds and refresh the view. Sometimes the view presentation may take a little longer than expected to load, and can be resolved by a view refresh.
Try resizing the main view pane by clicking the divider between the NavTree sidebar and the main view and drag the divider slightly to the left or right which causes the main view pane to “paint”.
Try restarting your browser. If using Workbench, close and restart it.
If the widget still fails to load, try opening another ux view, such as the User Manager view of the UserService, to see if that manager view loads successfully.
- If the User Manager view does not load, there may be a more general problem.
- If the User Manager view loads fine, you may have a problem with the ux module providing the Device Registration view. This could be because your cloudSentienceConnector-ux module has been corrupted, possibly due to IT algorithms stripping "potentially dangerous" files from within the jar file when emailing it to other users. To confirm that this is the problem, see “Confirming Niagara Modules” after delivery for details on how to tell if the module is affected.

Solution

If your cloudSentienceConnector-ux module is corrupted, you need to obtain a valid version of the module, either by downloading it directly from Niagara Community Software portal, or from a trusted source.
