Show buttons only to users in a group

Hi, I have a module in wich everybody has read permissions, but only some users belonging to a group are allowed to take actions. So I would like to show my workflow buttons only to these users.

I tryed to add the groups="group_name" attribute to the button, but I when I update my module I get an Arch Error. What is the right way to do this?

EDIT - Question Reformulation!

Thanks for your answers, but it is not what I was looking for. I know that adding the "groups" attribute to a field, it hides it from users that don't belong to that group. My question was if there is anything similar to buttons.

If I have this code on my xml <button name="wtv" string="whatever" groups="my_group" /> it rises a "Invalid XML for View Architecture", so I guess this isn't a valid option for buttons.

The full trace like this:

Try this in your xml file... <field name="name" groups="base.group_userB"/>. Now the userB group only can view the field....

Maybe you typed a wrong group name , or maybe the group name is related to another module that is not referenced in the dependencies of  the __openerp__.py

example in a module :

<field groups="product.group_product_variant" name="variants"/>

You call the group "group_product_variant" that belongs to the module "product". So the __openerp__.py should have the module "product" in the "depends" declaration

In the same way, you must refer to this group by prefixing with the name of the module : product.group_product_variant
