== Template:KnownIssueDupCheck ==

Place this '''once''' on a page that uses [[Template:KnownIssue]] (typically just
above the table). It scans the page source and shows a red warning for either of:

* '''Duplicate IDs''' — an integer <code>ID</code> used by more than one <code>KnownIssue</code> (these would emit the same <code>#KnownIssue''N''</code> anchor twice).
* '''Missing IDs''' — rows with no <code>ID</code> assigned.

Each is a separate message. When everything is clean it renders nothing.

<pre>
{{KnownIssueDupCheck}}
{| class="sortable wikitable"
...
{{KnownIssue | ID = 73 | ... }}
{{KnownIssue | ID = 74 | ... }}
|}
</pre>

=== How it works ===

It reads the current page via <code>mw.title.getCurrentTitle():getContent()</code>
(see [[Module:KnownIssue]]) and counts <code>ID</code> parameters across '''every'''
<code>KnownIssue</code> call on the page, including <code>hide=yes</code> and
<code>anchor=no</code> rows.

=== Caveats ===

; Saved revision only
: <code>getContent()</code> returns the last '''saved''' version of the page, so
while previewing an unsaved edit the check will not yet reflect your changes —
save and reload to re-run it.

; Source-level
: It counts literal <code>KnownIssue</code> calls in the page source; issues
pulled in by transclusion from another page are not seen.

; Expensive
: <code>getContent()</code> is a MediaWiki "expensive" parser call. One use per
page is well within limits.
