PHP eval returns null but a return is called

[agor]

I have a, I think fairly easy, question, but I can't figure out what I'm doing wrong. I have a function which i call with PHP's function \[code\]eval\[/code\]. I'm expecting an, selfbuilt, ArrayList to get as a result. But instead when I use \[code\]gettype\[/code\] I see the result is \[code\]NULL\[/code\]. Even though I'm using \[code\]return\[/code\] in the eval-ed function.As far as I'm aware I'm playing it by the documentation, but somehow it's not working. Any suggestions?Code fragment\[code\]<?php $widgetList = new ArrayList(); for($i = 0; $i < $selectedTemplate->Regions->count(); $i++) { $region = $selectedTemplate->Regions->item($i); if($region->Widget->selectiveContent == 1) { $widgetList->add($region->Widget); } } if($widgetList->count() > 0) { ?> <tr> <td colspan="2"> <strong>Widget instellingen</strong> <hr size="1" width="100%" color="#333"/> </td> </tr> <?php for($i = 0; $i < $widgetList->count(); $i++) { ?> <tr> <td class="w150"> <?= $widgetList->item($i)->title ?> </td> <td> <select name="widget_<?= $widgetList->item($i)->id ?>" class="full"> <?php $itemList = eval($widgetList->item($i)->functionCall); for($j = 0; $j < $itemList->count(); $j++) { $selected = null; if($_POST["widget_".$widgetList->item($i)->id] == $itemList->item($j)->id) { $selected = " selected=\"selected\""; } ?> <option value="http://stackoverflow.com/questions/2045458/<?= $itemList->item($j)->id ?>"<?= $selected ?>><?= $itemList->item($j)->title ?></option> <?php } ?> </select> </td> </tr> <?php } } ?>\[/code\]Eval-ed code\[code\]public function getNavigationByLanguageId(Integer $parent, ArrayList $objectList, Integer $language) { $query = DataAccess::getAdapter()->query(" SELECT * FROM `navigation` WHERE `parent_id` = ".$parent->value." AND `language_id` = ".$language->value." AND `website_id` = ". $_SESSION["currentSite"]["id"]." ORDER BY `sort_order`"); while($result = DataAccess::getAdapter()->fetchAssoc($query)) { $link = new Model_Navigation(); $link->id = $result["id"]; $link->language = $result["language_id"]; $link->parent = $result["parent_id"]; $link->Page = Model_Page::getPageById(new Integer($result["page_id"])); $link->title = $result["title"]; $link->externalUrl = $result["external_url"]; $link->sortOrder = $result["sort_order"]; $objectList->add($link); Model_Navigation::getNavigationByLanguageId(new Integer($result["id"]), $objectList, $language); } return $objectList; }\[/code\]The function being eval-ed is: \[code\]Model_Navigation::getNavigationByLanguageId(new Integer(0), new ArrayList(), new Integer(7));\[/code\]Some more explaination about the codeI'm using this funcitonality in my new CMS. A user is able to design a template and place widgets in defined regions, pretty much like the portlet functionality jQuery is providing. Widgets are installed for a website by me, I have built in an option to provide a functioncall to retrieve a list of objects when a widget is flagged as 'Selective Content'.What I'm trying to achieve here is using \[code\]eval\[/code\] to return ArrayLists from the value of $widget->functionCall.
