I’m attempting to do something that is very simple with a DataProvider such as ListDataProvider, but I cannot figure out how to do with an implementation of a BackEndDataProvider. I am essentially trying to duplicate the result from the first example for filtering a grid at https://vaadin.com/components/vaadin-grid/java-examples/filtering, where the grid filters the data down based on multiple queries. Due to the lack of the far easier to use addFilter() method I’m hitting a huge roadblock in my ability to do this.
Is there a standard way to go about this? An extremely similar question was asked here some months ago, solving their problem would solve mine.
