Under Jaspersoft Domains, is it possible to change an attribute (e.g.: "Week" attribute) so that a date picker (calendar) is displayed when filtering, instead of a dropdown/list?
The type of the attribute cannot be changed and it depends on the underlying type of the attribute in the database.
In the earlier example, "Week" attribute comes from DWH_CMN_PERIOD_V.PERIOD_NAME (Type: VARCHAR2), therefore, it cannot be filtered with a calendar, as it it is for "DATE". The values that appear are the period names that already exist.
Another attribute, "Week Start Date" is based on DWH_CMN_PERIOD_V.PERIOD_START_DATE (Type: DATE), so this one will display the calendar in the filter.
