[Bug - 12824] NullPointerException: WindowInfo for window

Ignition Early Access
1

I did just duplicated my 7.9.10 server for a upgrade to 8.0 test. Seemed to fail in the same matter. Only grey screen when launcing vision clients.

Console:
Exception in thread “AWT-EventQueue-0” java.lang.NullPointerException: WindowInfo for window com.inductiveautomation.vision/windows/PerfectChat was null.

This issue was fixed recently, can you try with last night’s build?

4

Okay, thanks, must not be fixed or merged yet :confused:

5

I’ll check again tomorrow. :wink:

6

I tested it again with new version but get same result.

7

This issue was fixed in the build that was uploaded today (2/21). Please let us know if you continue to see this behavior after upgrading.

Hi,

I tested with the latest build, and I can say that I got better results. I can see our main start up window, but our navigation window is nowhere to find. 7.9.10 project restored.

9

Load on start up was not ticked. Simple fix.

Hello,

We have this same issue on a old project that can be loaded either in 7.6, 7.7 and 7.9 without issues. When trying to run it in 8 we receive the following error

The mentioned window “Header” is marked as Open or Startup. One thing to mention is Header window is contained under the sctructure Vision\Windows\Header\Header (that is, there’s a parent folder named Header which contains also other window related to header). The rest of windows in the project are organized the same way, under folders, to allow a better organization for all the windows in the project and that hasn’t been a problem in previous versions of Ignition. Is that a problem in Ignition 8?

What build did you encounter this on?

12

8.0.0-beta0 (b2019020602)

13

Could you please try a newer build? This looks similar to a different issue we fixed over the weekend.
If you have a Gateway backup from before this occurred, please upgrade and then restore from backup.

14

Ok. Current download link for version “8.0.0-Nightly” in page https://inductiveautomation.com/downloads/ignition-8-beta is OK?

15

Yes. Going forward, you'll want to stick close to the most recent build; we're introducing fixes and new features at a pace that make a month-old build almost impossible to validate against. In your case, this thread claims that a fix has already been put in place:

So I want to say you should be fine.

16

Will upgrade and it should be fine afterwards then, many thanks!
