[TYPO3-english] Adding template to extension

[Andre Cheung Tam He]

Hi,

I'm relative new to Typo3 extension programming.
The alpha extension I made with kickstarter is working fine (getting 
data and displaying it).

Now I want to add an template to make the extension more flexibele and 
the problems start ;-)
I followed this wiki entry:
http://wiki.typo3.org/Extension_Development,_using_HTML-Templates

I created an ext_typoscript_setup.txt in the extension root folder 
(typo3/typo3conf/ext/lucas_helpdesk) with this line:
         plugin.lucas_helpdesk.templateFile = 
EXT:lucas_helpdesk/template.html

Created an template.html in the extension root folder with these lines:
<h3>TEMPLATE</h3>
<p>This is a simple HTML template.</p>
<!-- ###TEMPLATE### begin -->
<h1>###MARKER1###</h1>
<h1>###MARKER2###</h1>
<!-- ###TEMPLATE### end -->

Added code as mentioned in the wiki to the 
class.tx_lucashelpdesk_pi1.php file:
         // Get the template
         $this->templateHtml = 
$this->cObj->fileResource($conf['templateFile']);

         // Extract subparts from the template
         $subpart = $this->cObj->getSubpart($this->templateHtml, 
'###TEMPLATE###');

         // Fill marker array
         $markerArray['###MARKER1###'] = 'content for marker 1';
         $markerArray['###MARKER2###'] = 'content for marker 2';

         // Create the content by replacing the content markers in the 
template
         $content = $this->cObj->substituteMarkerArrayCached($subpart, 
$markerArray);

         return $this->pi_wrapInBaseClass($content);

I get an empty page because, my guess is, $conf['templateFile'] is empty.
Which step am I missing?(I cleared the frontend cache)

Kind regards,

André
