Passing filter parameters between DeepSee Dashboards

Did you ever get a resolution to your question?

By values of a filter, do you mean the list of drop down entries that a user would choose in the filter?

If that is what you are asking and assuming your dashboards are all  built from the same cube, you can share filter values across the them  by creating a KPI class ( Extends %DeepSee.KPI) that contains all those shareable common things like filters or actions. Then extend the cube class with this KPI. This way the items of the KPI become available in the dashboards and then it is just a matter of attaching the individual items to widgets of the dashboard.
