Re: HP PPM Team Manager preconfigured portlet issue
these are not out of the box portlets from PPM.
They must have been configured by someone in your organization.
The error is shown by design. The chart might be shown correctly in the preview page but on the dashboard it throws out the error message. Please see the comment on the top of the "Portlet Definition Preview" page:
"This is a portlet definition preview. It is not a live portlet so all links are disabled. Please note that the preference values used to render this portlet are the default preference values configured for this portlet definition."
Please double-check the portlet definition since it seems to have errors.
