ListGrid filtering problem in 11.0 showcase

[Blama]

Hi Isomorphic,

please add this line to sample #gridCellWidgetsByRecord (v11.0p_2017-05-04):

    showFilterEditor: true,

For me, filtering in any of the columns does not work.
I get this in the Developer Console:

11:17:29.054:TMR3:WARN:ListGrid:isc_ListGrid_0:No DataSource or invalid DataSource specified, can't create data model

Isn't filtering supposed with client only data specified via data like in the sample supposed to work anyway?
This issue is not important for me, I just wanted to use the sample to test another filter-related behavior and my real ListGrid is also using recordComponents.

Best regards
Blama

See listGrid.filterLocalData: filtering always requires a DataSource (we need to know which are valid fields to filter on, and we need field types), but you can have a DataSource and provide data as a fixed array if you set filterLocalData.
