Is there an ETA on the fix for this?
I’ve run into the same issue passing datasets into popups.
Bug #802 (Encoded datatypes as parameters in embedding component) was resolved in 8.1.2. Bug #1083 (Encoded datatypes in Popups/Docked Views) was resolved in 8.1.4. 8.1.4 is available as a nightly as of today, but the RC is still at least a week out I believe - and then the stable release would be about two weeks after the RC.
*Encoded datatypes refers to datasets and dates.
