Task Charts page is empty

In documentation for product (9.0) I found, that

but in my installation this page is empty…

I tried to check permissions (even when I’m in “My webMethods Administrators” group) and it’s enabled (if disabled I won’t see the link in menu I think)

Any idea what I can check?


I also tried “Creating a Task Chart Portlet” chapter from the same document, but drag and drop is not working for me when I’m logged in as a sysadmin.
