yes. when i was looking at this i thought about making the dataprovider paging param ints, but then the long return type didnt make sense.
since count() returns a long its feasible to request offsets in the long range - eg user presses last page and you actually have more rows then an int can hold. so rather then going with a mixed approach that made the code base a big mess i went with the biggest type everywhere, which is a long. what i did at my day job is to create an entity data provider that handles all these inconsistencies and castings and exposes a consistent api to how our application works... -igor On Fri, May 3, 2013 at 8:58 AM, Paul Bors <[email protected]> wrote: > All good and solid, but take for example Javax's Query API: > http://docs.oracle.com/javaee/6/api/javax/persistence/Query.html#setFirstRes > ult(int) > > Since Wicket's DataProvider now offers the first and count as longs, one > would have to cast first to an int to pass it through the JEE 6 API, right? > Or am I missing something? > > ~ Thank you, > Paul Bors > > -----Original Message----- > From: Igor Vaynberg [mailto:[email protected]] > Sent: Friday, May 03, 2013 11:45 AM > To: [email protected] > Subject: Re: Wicket 6.x and Repeaters API change to use longs > > 4.8.4 Aggregate Functions in the SELECT Clause The result of a query ... > > The Java type that is contained in the result of a query using an aggregate > function is as follows: > COUNT returns Long. > ... > > -igor > > On Fri, May 3, 2013 at 8:35 AM, Paul Bors <[email protected]> wrote: >> I'm a bit confused and can't find the JPA version that uses longs >> instead of ints as mentioned in the migration guide at: >> >> https://cwiki.apache.org/WICKET/migration-to-wicket-60.html >> >> Repeaters >> >> * `IDataProvider` was converted to using `long` instead of `int` to >> better line up with JPA and other persistence frameworks.
