is it possible to set the breadcrumbs from a portlet?
Is there an API for the breadcrumbs which I can use inside a portlet?
For example, I have a navigation bar with entries "Home" "Certificates" "License keys". When I click on "Certificates" then I want to show a list of existing certificates and breadcrumbs should show "Certificates -> List of all certificates". When I then click on a single certificates to edit it, then I want to show the edit form and the breadcrumbs should be "Certificates -> Edit certificate".
Thanks in advance for your help.
