in 4.58 the filter on the "Types" tab works correctly and shows the correct result.
The version of both "warnings-plugin" and "static-analysis-core" are different so I'm not sure which plugin causes the problem.

Is there some way I could enable some extra debugging in order to get to the bottom of the issue?

Fix for JENKINS-37195 is only in analysis-core: https://github.com/jenkinsci/analysis-core-plugin/commit/1dcfdc5df42790f55a51a4592923b65916385b0b
So if you downgrade the warnings plugin (without altering analysis-core) and it works afterwards then this must be something different. Is there a reason that you did not try the latest release 4.60? Which analysis-core do you use?

In 4.59 the default category has been changed to '-'. Maybe this is a problem with old builds? Happens the problem you are describing on a build that you started with the new plugin? Which types in the tab Types do you have?

I was using the very latest release of both warnings (4.60) and analysis-core(1.82), but I noticed the original behavior was broken so I reverted to very old releases of both warnings and analysis-core in order to see where the problematic code change occurred.

I then moved forward through the warning releases until the regression occurred. I noticed this happened when going from warnings:4.58/analysis-core:1.80 (working) to warnings:4.59/analysis-core:1.82 (not working)

Perhaps the problem is coming from analysis-core. I don't think I can run the latest warnings plugin with analysis-core 1.80.

For which type names does the link not work?

Is the build where the links do not work created with warnings:4.59/analysis-core:1.82?

I upgraded to warnings 4.58 and analysis-core 1.81 and the links are still working properly, so I suspect the regression is in analysis-core 1.82. Unfortunately I cannot try warnings 4.60 with that version of analysis-core as the minimum requirement is 1.82

The type names are like: SGDC_waive27 or WRN_47

Yes, it definitely is still broken even if the build is done with the latest release: warnings:4.60/analysis-core:1.82

Can you create some kind of debug build or give me a hint where I can look for the problem?

Also warnings 4.58 and analysis-core 1.82 is not working.

I spotted the problem! I should have seen this earlier in our conversion when you talked about the type and I about the category. The link needs to be have the 'type' prefix and not 'category'!

[FIXED JENKINS-42820] Fixed navigation into warnings by type.

I tested the snapshot build 1.83-SNAPSHOT on our jenkins server and it solved the issue.

Thanks for the very quick fix.
