Melissa was attempting to print Disbursements so she clicked the "Show Printable" button.  The filter results were more than she wanted to print so she attempted to add a date to further filter the results.  This resulted in the date filter box being outlined in red and the attached error in the usasapp log.

• In DisbursementCollaborator.PrintableFilter, we need to provide a proper implementation of appliesToProperty. This will allow the underlying framework to remove and re-apply the filter accordingly.

  • NOTE: In this case, we cannot determine if the filter applies to a particular property because it is not associate with a specific property. Therefore, per the documentation's suggestion in Vaadin's Container.Filter, we will return true for this method. Through experimenting, I found that if I set the return value to true, every subsequent filter that is added to the grid causes the printable filter to be removed. We want the printable filter to stay, therefore I will be returning false.
