Problem

after upgrading to mw 1.17 various dpl calls generate the following warnings,

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/aiowiki/aiowiki/w/includes/parser/ParserOptions.php on line 274
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/aiowiki/aiowiki/w/includes/parser/ParserOptions.php on line 289

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/aiowiki/aiowiki/w/includes/parser/ParserOptions.php on line 317

this can cause when using the namespace parameter in a dpl call, also when using

Extension:DynamicPageList (DPL), version 3.2.1: Warning: No results.

the templates and calls haven't been changed from before the upgrade and were working perfectly in 1.16.5, also the dpl call still gives the correct results

This seems to be a bug in MediaWiki itself. Bugfix for ParserOutput.php, line 340:

/**
 * Returns the options from its ParserOptions which have been taken 
 * into account to produce this output or false if not available.
 * @return mixed Array/false
 */
 public function getUsedOptions() {
    if ( !isset( $this->mAccessedOptions ) ) {
        return array();  // bugfix: return empty array instead of false 
        return false;
    }
    return array_keys( $this->mAccessedOptions );
 }

This should help.
