Hi,

one structure of my site is:
page->ReferenzCategoryHolder->ReferenzCategory->Referenz

ReferenzCategoryHolder and ReferenzCategory are extending page. Referenz extends dataobject.

ReferenzCategory:

static $has_many = array(
'Referenzen' => 'Referenz',
'Stammdaten' => 'Stammdaten'
);

In stammdaten.php i have placed my functions:

class Stammdaten_Thumbnail extends Image {

function generateThumbLogo($gd) {
$gd = $gd->PaddedResize(160, 90, "000000");

$gd->setQuality(100);
return $gd;
}

function generateThumbLogoGrey($gd) {
$gd = $gd->PaddedResize(160, 90, "000000")->greyscale();

$gd->setQuality(100);
return $gd;
}
function generateThumbLogoColor($gd) {
$gd = $gd->PaddedResize(160, 90, "000000");

$gd->setQuality(100);
return $gd;
}

function generateThumbLogoLaufband($gd) {
$gd = $gd->resizeByHeight(30);

$gd->setQuality(100);
return $gd;
}
}

in referenzCategory.ss i call the ThumbLogo function and it returns the thumbnail.

<% control getFirma %>
<div style="margin-bottom:10px;"><img src="$LogoDetailuebersicht.ThumbLogo.URL" title="$Firmenname, $Ort" alt="$Firmenname, $Ort" class="logo" /></div>
<% end_control %>

How can i use the function in referenzCategoryHolder.ss? $LogoDetailuebersicht.ThumbLogo.URL does not return anything.
How can i debug the scope of my functions?

Greetings from germany, Carsten.
