Visual CMS - shortcodes as module - OXID 6 EE

I made module with shortcodes for VisualCMS.

As example i used VCMS manual (page 18) and module ddoe.

In my module i’m using “Alternative: Smarty Template” solution. I have problem with parse() method - fetching from $oSmarty object won’t work.
"$oSmarty->fetch( ‘widgets/article_shortcode.tpl’ );" return nothing :frowning:

Normal solution with delivering content directly works ok.

Did anyone had the same problem?
