Kanban links are not invalidating the Obsidian cache

[gooseleggs]

I have an issue, where when I update a KanBan board card, by moving a card, the frontmatter gets updated, but after the first move, Dataviews or Bases do not update.

The only way I can remediate this, is by rebuilding the cache.

I talking about it on this thread: https://forum.obsidian.md/t/stuck-index-cache-bases-unaware-of-new-notes-outline-heading-link-suggestions-empty-rebuild-cache-button-inert/108785/42. It appears that this plugin uses app.vault.modify() to modify the file. However, the moderator has bounced me to you for you to investigate this issue and then raise it upstream if it is in fact a bug in obsidian.

I created a test vault which exhibits the problem: https://github.com/gooseleggs/ObsidianKanbanIssue

Can you please investigate and resolve please?

I think I have a fix for this, although I have not taken it more than what I need to.

I think that the app.vault.modify() is not invalidating everything that it probably should, ie frontmatter. I have changed to the Frontmatter API which reduces the size of the code, and also seems to make this work as it should. The updatePropertyInFile function is now this:

    async updatePropertyInFile(property, newValue, file) {
		    const fileContents = await this.app.vault.read(file);
		app.fileManager.processFrontMatter(file, (frontmatter) => {
				frontmatter[property.key] = newValue;
		});
    }

There is probably a lot of other fixes to be done throughout the code, but this gets the Kanban helper working again (at least for me)
