Silverstripe does not use custom template

Question

I am using Silverstripe and i am really confused. I created Holder and Page class and theirs .ss files.

mysite/code/NewsPage.php

class NewsPage extends Page {
    static $db = array('Date' => 'Date', 'Author' => 'Text');

    public function getCMSFields() {
        $fields = parent::getCMSFields();

        $fields -> addFieldToTab('Root.Main', $dateField = new DateField('Date', 'Date'), 'Content');
        $dateField -> setConfig('showcalendar', true);      
        $fields -> addFieldToTab('Root.Main', new TextField('Author', 'Article author'), 'Content');        

        return $fields;
    }
}

class NewsPage_Controller extends Page_Controller {

        public function init() {
        parent::init();
    }
}

mysite/code/NewsHolder.php

class NewsHolder extends Page {
    static $allowed_children = array('NewsPage');   

}
class NewsHolder_Controller extends Page_Controller {

    public function NewsList() {        
        $holder = NewsHolder::get()->filter('ID', $this->ID);
        return ($holder) ? NewsPage::get()->filter('ParentID', $this->ID)->sort('Date DESC')->limit(3) : false;    
    }
}

templates/Layout/NewsPage.ss

<article>
    <h2>$Title</h2>
    <div class="content">
        $Content
    </div>
    <p class="author">
        $Author
    </p>
    <p class="info">
    $Date.Format("d.m.Y")
    </p>
</article>

templates/Layout/NewsHolder.ss

<% loop $NewsList %>    
 <article>
   <h2><a href="$Link">$Title</a></h2>
   <p class="demo">
     $Content.FirstParagraph ...
   </p>             
 </article>
<% end_loop %>

These classes is for articles and works fine. I copied these codes for GalleryPage and GalleryHolder which I want for pictures. The problem is that Silverstripe do not use GalleryHolder.ss but default Page.ss template.

I cannot figure out why. For NewsPage.ss and NewsHolder.ss it works fine, but exactly same code in another classes (GalleryPage and GalleryHolder) use default Page.ss. Code is the same, I just changed all NewsPage or NewsHolder strings to GalleryPage and GalleryHolder.

Edit : copied code for Gallery pages

mysite/code/GalPage.php

class GalPage extends Page {
    static $db = array('Date' => 'Date', 'Author' => 'Text');

    public function getCMSFields() {
        $fields = parent::getCMSFields();

        $fields -> addFieldToTab('Root.Main', $dateField = new DateField('Date', 'Date'), 'Content');
        $dateField -> setConfig('showcalendar', true);      
        $fields -> addFieldToTab('Root.Main', new TextField('Author', 'Article author'), 'Content');        

        return $fields;
    }
}

class GalPage_Controller extends Page_Controller {

        public function init() {
        parent::init();
    }
}

mysite/code/GalHolder.php

<?php
class GalHolder extends Page {
    static $allowed_children = array('GalPage');    

}
class GalHolder_Controller extends Page_Controller {

    public function NewsssList() {      
        $holder = GalHolder::get()->filter('ID', $this->ID);
        return ($holder) ? GalPage::get()->filter('ParentID', $this->ID)->sort('Date DESC')->limit(3) : false;    
    }
}

templates/Layout/GalPage.ss

<article>
    <h2>$Title</h2>
    <div class="content">
        $Content
    </div>
    <p class="author">
        $Author
    </p>
    <p class="info">
    $Date.Format("d.m.Y")
    </p>
</article>

templates/Layout/GalHolder.ss

<% loop $NewsssList %>  
 <article>
   <h2><a href="$Link">$Title</a></h2>
   <p class="demo">
     $Content.FirstParagraph ...
   </p>             
 </article>
<% end_loop %>

Can you please give me some advice how to fix the problem ?

Answer 1

As 3dgoo said - have you placed the template files within the themes directory? Also, sometimes manually clearing the cache (i.e. delete the files in silvestripe-cache folder) helps.

Answer 2

Your folder 'layout' should be 'Layout' (case-sensitive).
