[Mediawiki-l] Extension crashes in 1.4.0

[Jean-Christian Imbeault]

While trying to get an extension to run I got the following in my apache 
error logs. The extension worked fine in 1.3.10

[error] PHP Warning:  end(): Passed variable is not an array or object 
in /home/imbeauje/apache/htdocs/wiki/includes/Parser.php on line 425
[error] PHP Warning:  end(): Passed variable is not an array or object

[error] PHP Fatal error:  Unsupported operand types in
/home/imbeauje/apache/htdocs/wiki/includes/Parser.php on line 373

In case it is useful here is my extension:

$wgExtensionFunctions[] = "wfTableSchema";

function wfTableSchema() {
   global $wgParser;
   $wgParser->setHook( "tableSchema", "renderTableSchema" );
}

function renderTableSchema( $input )
{
   global $wgTitle, $wgParser;
   $CLASSPATH =
"/home/imbeauje/WEBTEAM/HEAD/mrw/Tools/src/:/home/imbeauje/WEBTEAM/HEAD/mrw/Tools/lib/jconn2.jar";
   $title = $wgTitle->getDBkey();
   //title is of the form database..tableName. Parse to extract
   list($dbName, $tableName) = explode("..", $title);
   $dbName = strtolower($dbName);
   //then pass as params to java prog that will generate table
   $cmd = "/home/imbeauje/j2sdk1.4.2_06/bin/java -classpath $CLASSPATH ".
          "com.mizuho.rws.tools.wikiTools.WikiDatabaseTableGenerator $dbName
$tableName";
   $output = `$cmd`;
   $output = $wgParser->internalParse($output, 0);
   return $output;
}
?>
