Setting the parent attribute does not make sense in this configuration file - this attribute is not supported at all and will be ignored. "parent" is an attribute that you use in Spring configuration files, not the Alfresco Share configuration files. As always, the source of Alfresco is the best example to look at for usages of chainedAll etc.
Thanks for the link! got the impression that I cannot chain together an evaluator which is checking user group membership and another one which is disabling a certain action.
Run into a demand, where I need to be able to hide certain document action based on the role of the logged in user. Basically I need to create company specific action groups out of the standard actions and show them depending on the user role.

By group membership I thought about a more generic kind of organization, like defining roles inside the company, and not inside the Alfresco's Share site (consumer, contributor, colaborator and manager).
