Error list keeps showing old cached results after the first render

[setzer22]

I've updated my emacs packages, and I noticed this issue. It seems to be related (or identical) to #149, but I've been able to reproduce this in other language servers I use (clojure and rust), which leads me to believe it is a general issue with lsp-treemacs itself, and not something that depends on the language.

The problem is the following: When I open a project, LSP diagnostics work okay in the buffer, and the first time I launch lsp-treemacs-error-list, I see the correct output. If I then make any changes to my LSP setup, lsp-treemacs-error-list keeps showing the old errors indefinitely. I haven't found a way to make it refresh the contents other than restarting emacs.

This is a quick screen recording of my interaction:

I was able to successfully bisect the issue to the following commit: e668656

Unfortunately, the commit is large enough that I cannot continue debugging without a better understanding of the codebase. This seems to be a caching issue, and the fact there's multiple references to caches in the commit source makes me believe that is the case.

Same with lsp-java and lsp-treemacs-references.

Unable to repro. Can you verify that it does not work with M-x lsp-start-plain?

(updated my comment to mention lsp-treemacs-references which was causing problems on DOOM emacs.)

M-x lsp-start-plain works fine. thanks for the tip @yyoncho - wasn't aware of this one before. Unsure what's causing this then.
