error when adding products

Hi, I get the following error when adding a product:

Warning: Invalid argument supplied for foreach() in public_html/administrator/components/com_hikashop/classes/field.php on line 102

Using joomla 1.7 and hikashop business 1.5.4

Hi,

Thank you for the report.

You can fix that by changing the code:
foreach($loadedCategories as $cat){
$categories[$data->product_id][$cat]=$cat;
}

to:
if(!empty($loadedCategories)){
foreach($loadedCategories as $cat){
$categories[$data->product_id][$cat]=$cat;
}
}

in that file.

Thanks Nicolas, that fixed it
