Thanks Thiago, I have built a JPA datasource provider that is similar to the hibernate one, and it manages filtering, sorting and paging so the size of a grid is not an issue; I was declaring that the dataset is verylarge only to explain the reason why I cannot use an autocomplete/drop down field.
Regarding the "user interface question", well, ehrrr... ehm... I was using tapestry exactly to build the user interface, so I was appreciating the grid that allows me to show many columns to the user. I was simply hoping to find a "standard" way to solve this issue, if I'm the first one to have this need may be I choose the wrong tool for this task :-) Thanks again, Luca > Sent: Monday, August 03, 2015 at 7:42 PM > From: "Thiago H de Paula Figueiredo" <thiag...@gmail.com> > To: "Tapestry users" <users@tapestry.apache.org> > Subject: Re: Filling some filed of a form selecting a row from a grid > > On Mon, 03 Aug 2015 13:55:54 -0300, Luca Arzeni <l.arz...@iname.com> wrote: > > > The point here is that the list needs to be shown in a grid since it has > > more than 100.000 items, and I need to allow the user to filter it > > according to few criteria (that I've already implemented in the page > > that contains the grid). > > Remember the source parameter of Grid receives a GridDataSource object, > not a List, so just implement it to do the search you need to do with > paging (i.e. retrieve just the objects you'll show right now). > tapestry-hibernate already has HibernateGridDataSource, which already > implements a part of it (pagination) and you just need to provide the > query criteria. > > > By the way: the user needs to see a list of customers since many users > > have similar values (same name, same city...) so he needs to examinate > > more than one field to choose the right one (which is the reason why a > > show a list of customers in a grid). > > This looks more of an user interface question than a Tapestry one, to be > honest . . . > > -- > Thiago H. de Paula Figueiredo > Tapestry, Java and Hibernate consultant and developer > http://machina.com.br > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org > For additional commands, e-mail: users-h...@tapestry.apache.org > > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
