products module (get category )

[per]

Hi.
I want to show a list of products of the same category below a detail product.
some like this:
{Products lang="es_ES" action="default" category="$category->name" sortby="random" pagelimit="2"}

But i get "Catchable fatal error: Object of class stdClass could not be converted to string in /home/sanatori/electrodomesticos.com.py/tmp/templates_c/Products^%%DE^DE2^DE2A799D%%module_db_tpl%3AProducts%3Bdetail_Sample.php on line 106"

I try some variants but I cant get solution.

Anyone can help me?

Thanks.
