Using applyJsonFilters on a Date Hierarchy

[JonasV]

Hi folks,

I am desperately trying to get applyJsonFilters to work on a Date Hierarchy. No matter what I try (TupleFilter, HierarchyFilter), nothing works. I really have no clue how to get around this. The normal TupleFilter on all other dimensions works just fine.

Simply nothing happens.

Does anyone have a working example for this? I couldn't find anything about this.

All the best,

Jonas

For anyone looking into this in the future:

In the meantime I found a solution, which I am not sure of if it the way it is supposed to work. If you are using the example from the documentation

https://learn.microsoft.com/de-de/power-bi/developer/visuals/filter-api

you have to read the following property from the powerbi.DataViewMetadataColumn:

column.identityExprs[0].source.entity

and pass this as the table property for the 

IFilterTarget

The rest works as in the example. Then you can add date columns for the TupleFilter.

Unfortunately this isn't in the typings. This has to be made fail safe by additional coding, of course.

If somebody has a better solution to this I would be glad to hear about it.
