Weird code... An array never gets populated, yet it exists in the final HTML

[akanevsky]

showthread.php, code:

PHP Code:

    require_once(DIR . '/includes/functions_editor.php');

    $vBeditJs = construct_editor_js_arrays();
    eval('$vBeditTemplate[\'clientscript\'] = "' . fetch_template('editor_clientscript') . '";'); 


Template editor_clientscript contains $vBeditJs[smilie_options_array]... Yet, the only place where $vBeditJs[smilie_options_array] ever gets populated is within the construct_edit_toolbar function, which never gets called on that page (or at least not according to the structure of the if clause)....

If I var_dump($vBeditTemplate['clientscript']), it has this:
var smilieoptions = new Array(); smilieoptions = { };

Yet in the final page:

var smilieoptions = new Array(); smilieoptions = { 
	'Generic Smilies' : {
		'16' : new Array('http://www.site.com/interactive/images/smilies/smile.gif', '[smile]', 'Smile'),
		'13' : new Array('http://www.site.com/interactive/images/smilies/icon_cheesygrin.gif', '[grin]', 'Cheesy Grin'),
		'18' : new Array('http://www.site.com/interactive/images/smilies/icon_sad.gif', '[sad]', 'Sad'),
		'35' : new Array('http://www.site.com/interactive/images/smilies/icon_wink.gif', '[wink]', 'Wink'),
		'21' : new Array('http://www.site.com/interactive/images/smilies/icon_eek.gif', '[shock]', 'Shocked'),
		'28' : new Array('http://www.site.com/interactive/images/smilies/icon_razz.gif', '[razz]', 'Razz'),
		'22' : new Array('http://www.site.com/interactive/images/smilies/icon_confused.gif', '[confused]', 'Confused'),
		'30' : new Array('http://www.site.com/interactive/images/smilies/icon_redface.gif', '[oops]', 'Embarassed'),
		'27' : new Array('http://www.site.com/interactive/images/smilies/icon_mad.gif', '[mad]', 'Mad'),
		'49' : new Array('http://www.site.com/interactive/images/smilies/sick.gif', '[sick]', 'Sick'),
		'more' : 'Show all Smilies'
} };

Any suggestions as of where it gets populated?
