NPE from SwingObjectWidget about scijava-ui-swing

[ctrueden]

Oof, very sorry this happened. I'm working on fixing the breakages in the ImageJ macro language syntax highlighting and autocompletion, but will look into this also in the very near term.

@karlduderstadt I pushed one quick fix (cbc9ef6), with some defensive programming around the case where the value to be rendered is null. I don't know whether this gets the root of the bug (I don't know if the value should be null here...), but it should prevent the crash you are seeing. Feel free to give it a try by building scijava-ui-swing from source.

Thank you very much! Yes, bad timing 😭 I should have tested more with the bundle you posted. my mistake. I think it is a great idea to send out the jars in advance like you did a couple times a year before big releases! I was certainly aware it was coming thanks to your posts and discovered the problem quickly.

I was also trying to come up with a minimal example of object retrieval in scripts in Fiji independent of Mars to confirm this is a general problem and not just our problem, but I haven't been able to develop that yet.

Will do, thanks a lot!

Thanks for the fast feedback. I don't get the NPE anymore, but the dialog comboBox has no choices anymore so this doesn't help much.

For now I pushed my copied version that overrides the problem to our update site yesterday. I am just still confused what is going on here.

@karlduderstadt When you have time: could you please test whether d40832c fixes your issue?

[karlduderstadt]

Yes @ctrueden that fixes the problem. I get list options again without any errors!

This does make me wonder why the choice list is empty in this case and whether there is something missing in my implementation...

In any case, thank you very much for the quick fix, I will close the issue and remember to test our scripts when you announce the next major update!
