I suggest to use

public String getDateFormat(Object propertyId)

in FilterDecorator insted of DateFormat (as return type), in order to set the date format to the DateFields

To have a better change of getting the change into Vaadin, I suggest you create an enhamcement ticket at
. I do have to confess that I’ve never heard of FilterDecorator, so can’t really comment on the validity of the request. But I’m sure that the dev team will.

I assume this is just a duplicate of the post about FilteringTable in that thread, and simply doesn’t mention what add-on this is about.

That add-on is not a Vaadin Ltd add-on and not handled through the Vaadin Trac.
