Gary, No, I understood what you meant. I really do think that that is out of the scope. The main point of display tag is to take the contents of a list and display it and provide a high degree of flexibility and configurability in that display. As soon as you start to add manipulation of the data onto that task, the other functionality is going to suffer. Especially as soon as you start to talk about using Ajax to handle the updates! A nice technology, but still a nightmare to work with, IMO...
Also, it's really a violation of the model and view separation paradigm. The display (ANY display, not just display tag) really shouldn't be in the business of manipulating and selecting data. That's a metaphysical question of course (is filtering "manipulating"? I'd say yes, you might say no :^). But fear not, there's a simple way to deal with your issue. Add a text box at the top of your table (you can even put it in the displaytag.properties resources so that it'll always appear in the table header). Add something to your controllers to handle submitted filter requests. We have this sort of thing all over our code. Basically we have drop-down lists that let you view items by date submitted, type of product, etc. (we don't have a text box that allows free entry, but at the controller level, there's really no difference). To preserve sorting and ordering params from displaytag, we recycle the parameters using a function on the controller that cooks up the action url for the filter handler. Then when we redirect back to the actual display page, those all get stuck on the end of the URL along with the new filter criteria. In the end, I think it's much better to handle the filtering yourself anyways. We usually just let the database handle it by specifying a WHERE clause. Yeah, we could do the filtering ourselves, but that's what the database is for. In other cases where the work of doing a query would outweigh doing the filtering ourselves, we just do it ourselves, but it's pretty straightforward (regex matching, criteria ranges, etc.).
