W2L sometimes uses wrong reference-definitions (was: Detected bug in an extension! Hook Wiki2LaTeXHelper::UnknownAction failed to return a value; should return true to continue hook processing or false to abort.)

[GoogleCodeExporter]

What steps will reproduce the problem?
after installing currenct RC of W2L I get following error message when
trying to use the extension:

Detected bug in an extension! Hook Wiki2LaTeXHelper::UnknownAction failed
to return a value; should return true to continue hook processing or false
to abort.

Backtrace:

#0 /opt/lampp/htdocs/wiki/includes/Wiki.php(526):
wfRunHooks('UnknownAction', Array)
#1 /opt/lampp/htdocs/wiki/includes/Wiki.php(63):
MediaWiki->performAction(Object(OutputPage), Object(Article),
Object(Title), Object(User), Object(WebRequest))
#2 /opt/lampp/htdocs/wiki/index.php(116):
MediaWiki->initialize(Object(Title), Object(Article), Object(OutputPage),
Object(User), Object(WebRequest))
#3 {main}

What is the expected output? What do you see instead?
The expected output is, that I get a Tex-Output. Instead I see the posted
error message

What version of Wiki2LaTeX are you using? On which Mediawiki version?
W2L 0-10 RC 
Mediawiki 1.15.1

I will look into it. It might be a compatibility issue for W2L hasn't been 
tested
with MW 1.15.

Thank you for reporting the issue. It will be solved with in the next version.

I ran into the same issuu when installing Wiki2LaTeX. Newer versions of PHP are
stricter when it comes to arguments being incorrectly passed (by reference vs by
value). Here is a quick fix:

In w2lHelper.php, line 121, replace

    public function UnknownAction($action, &$article) {

by

    public function UnknownAction($action, $article) {

There are probably other similar errors, for example in line 21 of 
contrib/math.php.

Dear All, I downloaded w2l in March 2010 and made some modifications on it. The 
final version is available here: 
http://wmi.math.u-szeged.hu/~kovzol/w2l-0.10rc+kovzol20101015.zip. The .zip 
contains the following minor changes:

* Table handling (ltablex)
* Images
* Configuration changes:
  - disable references in the printed version
  - frenchspacing
* Colored verbatim paragraphs
  - lavender color for input (first block)
  - skyblue color for output (last block)
* Hungarian language support
* Math formulas displayed properly (fix)

The changes are not intended to be perfect, however they should work in most 
cases.

Best regards,
