Binding Tags as named query parameters in perspective

I’m trying to put together my first perspective client and I’m having all sort of issues with the named queries. Boatloads of error-exceptions and configuration errors. Literally the exact same named queries from a vision client, but tag binding seems to need to be done differently or is just broken all together. DateTime types have not worked once for me when passes as parameters through the perspective query bindings.

Has anyone had any success with using tags as parameters in perspective prop binding?

Mind posting some of those errors and elaborating on the scenario? On a related note, screenshots are useful in cases like these.
