#532 Null Pointer Exception when saving with Audio Buffer with url not set

[Randy Burnet]

I created Audio Buffer IAB2 in a script without assigning a url. When I attempted to save my Layout Editor Panels I got a NullPointerException with no indication of why. I deleted IAB2 in the Audio Table and was able to save after that.

Any chance of a copy of the script to help replicate the issue please?

Also, if your JMRI machine is internet connected, could you also perform 'Help > Upload debugging info' once the error has been seen.

Thanks.

I cannot exactly recreate the issue as stated - saving with a 'blank' audio buffer works. However, re-loading that file with the 'blank' audio buffer does trigger a NullPointerException.

Please confirm the exact sequence to recreate the issue.

Many thanks.

Matt H:
Just sent an upload, not sure if it went through as my scripts went nuts in the background.
Bottom line:
execute in the Panels/Script Entry window:
buffer = audio.provideAudio('IAB1')

where IAB1 (or whatever number is new) didn't exist at all before in the Audio Buffer table, it will now show up with an 'Empty Buffer'
then try to save the Layout Panel file that now has this Audio Buffer table in it, and it will throw the exception and refuse to save.

Thanks Randy, got the debugging info.

It seems as though there is a subtle difference when creating AudioBuffer objects in the GUI versus via a script and I am able to replicate the issue in my development environment.

I'll work on a fix.

OK, fix has been applied and should be in next JMRI release
