How to get the portlet-hash css class for the Calendar portlet assigned to a custom portlet manager?

Question

I am trying to fix the monthly navigation of the calendar portlet assigned to the custom portlet manager. This manager is called from a specific page template with:

<div id="calendar"
    tal:content="structure provider:my.custom.portletmanager" />

Unfortunately, the manager does not display the hash shell for me, so I try to manually add the cssattr-portlethash css class to the above tag <div>to do the monthly navigation (refreshPortlet () needs this). I tried this:

from plone.portlets.utils import hashPortletInfo
class SectionHomeView(BrowserView):
    """SectionHome browser view
    """
    implements(ISectionHomeView)

    def __init__(self, context, request):
        self.context = context
        self.request = request

    @property
    def getHash(self):
        info = dict(manager = 'my.custom.portletmanager',
                    category = 'context',
                    key = '/my-section',
                    name = 'mycalendar',
                   )
        return hashPortletInfo(info)

Using this code, I get a hash, but calendar navigation still doesn't work. How can I access portlet information such as manager, category, key and name to calculate correctly?
