Description:
Halló,

I experienced in many Wikimedia Foundation wiki's that categories have been
added to EXISTING templates.

So far I do not know another method then making a minor change to the page
containing that MODIFIED template.

a) NEIGHTER purge will help
b) NOR deleting and restoring the page

Nevertheless if the problem affects HUNDEREDS of pages an automated method
should be available.

c) it would be usefull that purge should update the membership in the category
so that if you load the category page after, you will see the page purged before

d) if a page is restored the membership in the category should be updated so
that if you load the category page after, you will see the page restored before

f) if there are reasons not to modify action=purge then a more effectiv action
like action=update should be implemented

One way to rebuild categories is to run the refreshLinks.php maintenance script.
This is a very expensive operation. I do not believe there is any way of
effectively updating a single category listing without looking through the text
of /all/ articles.

I agree that there should be an action for a page to cause it to rebuild all
related index entries - text index, links, category links, etc. Although this
won't solve the problem of out-of-date category listings, at least it would make
it possible to manually update it without having to open each page and save it
again.

What might make more sense for dealing with category entries in templates would
be to have a refresh option associated with the template page. This could cause
a category refresh for all pages that include that template. However:

You can have nested templates. This complicates the process.
For each page that transcludes the template directly or indirectly, the entire

page has to be parsed (including all transclusions) for category membership.
This is, as they say, "non-trivial".

Some templates are transcluded into a huge number of pages. Consider {{stub}}

on en.wikipedia.

note on comment 0 item f)

comparing the "''actual code of a page''" (and knowing how it interpreted in the
wiki system) whith the result from action=purge and the known workarounds to fix
related bugs these can be split in:

a) requiring one (minor) edit to get the requested result
example(s):
bug 1119: Page move updates categories with sorting tweak
...

b) requiring more (minor) edits to get the requested result
example(s):
bug 1993: Categories added to templates are not added to including pages
duplicate of 39: changes to links in a template do not update 'links',
'categorylinks', etc for pages including it
bug 2258: Category links in image upload summary field have wrong sort key
bug 2327: sort key is not evaluated again if a page is moved
bug 2331: undeleting pages does not add the pages to categories
...

If you are not shure what is necessary to do (remove the categories and insert
them back again) you will need more (minor) edits. In addition a lot of
verifying and possible purging will be necessary.

The correct implementation of a more effectiv action=update or action=rebuild
should be a powerful workaround for all these situations. It is a "handling
tool" not a fix for the mentioned bugs.
