[Mediawiki-l] Hooking OutputPageBeforeHTML, no $wgParser->getTitle()?

[Daniel Barrett]

I wrote an extension that hooks OutputPageBeforeHTML and runs on every
page load, but intermittently, $wgParser->getTitle() returns NULL.
Anybody know why?

Here's the weirdest part: if you edit an article in IE and save it, then
when the article redisplays, $wgParser->getTitle() returns NULL.  But if
you edit in Firefox and save it, $wgParser->getTitle() returns the
correct Title object.

Any explanations?  Bug?  Or did I write something wrong?

The minimal code looks like:

<?php
// Run on every page load
new MyClass();

class MyClass {
  public function __construct() {
    global $wgHooks;
    $wgHooks['OutputPageBeforeHTML'][] = array($this, 'myMethod');
  }

  // Hook function
  function myMethod($parserOutput, &$text) {
    global $wgParser;
    $title = $wgParser->getTitle();
    if ($title) {
      echo "OK";
    } else {
      echo "bug";
    }
  }
}
