I'm trying to use models for the first time with the goal of adding column metadata just once and have it display in questions/dashboards created from the model. The issue I'm having is that for some reason the column metadata is not visible when a question built from a model is added to a dashboard. If I visualize just the question (outside of the dashboard) I see my column metadata (column types, descriptions, etc...) but when i add it to a dashboard all I see is the updated column names (from the model) with a sort links. I don't see how to view the column description once added to a dashboard. I want my end users to benefit from the extra info about each column. Is that bug or am I not understanding something?
A related issue that I'm seeing is that if you join 2 models together the visualization of that question includes the column metadata of the main model but the metadata of the joined model is completely lost. The col names get overridden with a new name that includes info about the join. The descriptions I set in the model are not visible.
I would very much like to use models but I'm struggling to understand what value they have if the metadata is lost in questions and dashboards. Any help would be appreciated. Thanks!
