NullPointerException when attempting "Device by Name" query

[Andrew Doble]

Since upgrading to SP2.3, we are having problems editing/creating specific queries.

When attempting to edit an existing, or create a new query, using Device(s) by Name - clicking on the hyperlink "name" causes the Criteria Configuration window is displayed.

It displays the message "Please wait, loading data..."

However the Java Console shows:

java.lang.NullPointerException

Whenever I have Java issues the first thing I do is clear all of the Java Caches. I go to Control Pannel and double click each Java entry and clear the cache.

Failing that you may want to try for a clean install of the JRE, in which case you'd delete all of the JRE's and let IM reinstall the one it wants.

Thanks for the reply, Rob. Unfortunately it didn't resolve the problem.

I have noticed that the exception logged above only occurs when creating a new query. If I attempt to edit an existing query's "device by name" condition I receive:

Fired off request event from DeviceNameDataObject.getData()

java.lang.NullPointerException

Note: This problem not just happening on my workstation, but any of my colleagues' computers.
