Hi Andrus,
I probably didn't write it clear enough.
The scenario is: show a page, which shows first five articles obtained
by paginated SelectQuery (via AJAX, using Adobe Spry -- but it occus
even if I load the page directly) -> click a button for a new page,
fill in the form and click save -> save the article to the database
and return to the previous page with the list (e.g. a new select
query) -> paginate through the pages to the last page, where the new
article is -> Exception (the last page is not loaded at all). And as
I've said before, if I change ordering so that the new record is on
the first page, I can browse through the pages with no exception.
The code:
SelectQuery select = new SelectQuery(Article.class);
select.addOrdering(realOrdering, isAscending);
select.setPageSize(pageSize);
List<Article> articles = (List<Article>)
this.dataCtx.performQuery(select);
int start = (page - 1) * pageSize;
int end = page * pageSize;
System.out.println("END --------------------- service method
call to
retrieve the list");
return articles.subList(start, (end > articles.size() ?
articles.size() : end)); // from here the exception comes
SQL log & stacktrace (what troubles me is that cayenne retrieves
EVERYTHING even though I've set setPageSize(5)):

Hi Dan,
Not even sure at this point that this is an issue of int vs.
long... I
wonder how the *new* object even appears in the paginated list that
was created *before* the new object? Or did I misunderstand something
about your scenario?
Maybe it would help if you could post the exception and the SQL log
preceding it.
Thanks
Andrus

Hi people,
I've bumped into an error with cayenne 2.0.4 and the only similar
things I found were this message
(http://cayenne.markmail.org/message/elln5rjlgrsdinxm?q=paging+cache+type:users
)
and the bug CAY-643 (and those linked to it).
What I do is that I load a page with paginated query (list of
articles, first 10), then I hit "new article" on the page, create
and
save the article and return back to the list.
Then I paginate to find the newly added article and when I enter the
page it is on and the page is the last page at the same time, I get
the CayenneRuntimeException with "Can't find id for [the newly added
article]" (i.e. when I set sorting to, let's say, by ID DESC --
which
puts the new article to the first page -- everythong is OK on all
pages)
I understand there is the problem with long vs. int and that it will
be fixed in 3.0, so how can I as a user prevent this error in 2.0.4?
This seems to me like a very common scenario in listing records and
doing CRUD operations, but it seems almost nobody encounters this.
Do
you guys adandon pagination and use raw sql?
I wanted to try 3.0M2, but when using it Stripes couldn't find any
ActionBeans url mappings -- strange.
Thanks for all hints in advance,
Dan
