GetStandardValuesSupported and GetStandardValues methods of a type converter are not called. Available in the 2017 R1 Release (2017.1.117).
If you have a data validation, and there is an invalid field with the red border around it, if you hide this field via the filtering feature or the collapsing its group, the validation red border (and the tooltip) disappears.
To resolve this, you will need to update the ErrorTemplate of the input field (the TextBox). You can do this in the FieldLoaded event handler.
Available in the 2017 R2 Release.
