Page not found

[obzerver]

Hi guys,
I've started playing around with designing my own plug-in. So far the guides have been great and I think I have a handle on what's going on. What I want to do is call my plug-in from a link and have it display content on the main page. However, when I try to call a page such as "http://mysite.com/index?page=my_plugin" I receive all the content that I have associated with theme_index_main with "Page not found" tagged on at the very end. So everything seems to be working except for that little message. I've searched and searched, but I can't find any help. I'm sure I've probably confused something along the way. Any help would be greatly appreciated! I've included a snippet of my code and file structure below.
Directories are as follows:
/content/plugins/my_plugin
my_plugin.php
/templates
my_template.php
/languages
my_plugin_language.php

<?php
/**
 * name: My Plugin
 * description: Test plug-in
 * version: 0.1
 * folder: my_plugin
 * class: MyPlugin
 * hooks: theme_index_top, theme_index_main
  */
 
class MyPlugin
{
    public function theme_index_top($h)
    {
        if($h->isPage('my_plugin')){
            $h->pageTitle = $h->lang["my_plugin"];
        }
    }
    public function theme_index_main($h)
    {
        if ($h->isPage('my_plugin')) {
            $this->mainPage($h);
        }
    }
    
    public function mainPage($h)
    {
        $h->displayTemplate('my_template');
    }

    
}
?>

You need to return true or false after displaying your template:

public function theme_index_main($h) 
    { 
        if ($h->isPage('my_plugin')) { 
            $this->mainPage($h); 
            return true;
        } 
    } 

The reason is the theme_main_index plugin hook in index.php is used to override the default page, which just happens to be 404error.php:

<!-- MAIN -->
                            <?php     
                                // plugin hook
                            $result = $h->pluginHook('theme_index_main');
                            if (!$result) {
                                $h->displayTemplate($h->pageName); // default is 404error.php
                            }
                            ?>

$result is actually an array of values returned from all plugins using the hook, so even returning false will make $result pass the if condition. If nothing at all is returned, "Page not found" will be shown.
