Hi all!
I think I discovered a bug with the pagination logic of Query objects.
I have a query object comments defined in my components.xml. max-results param
is set to 5 and I know that I have 10 comments in the DB. I can use the
following code for the rendering of a "next page" link:
<s:link view="/comments.xhtml" rendered="#{comments.nextExists}" value="Next
Page">
| <f:param name="firstResult" value="#{comments.nextFirstResult}"/>
| </s:link>
Now, when I'm already browsing the second and last page, i.e. with firstResult
param set to 5, a "next page" link is still there. When I click on "next page",
firstResult is set to 10 and the query object returns an empty list.
I went through the Query.java code and found this implementation for
isNextExists():
public boolean isNextExists()
| {
| return getResultList()!=null &&
| getResultList().size() == getMaxResults();
|
| }
I think this code should consider the resultCount as well, so that
getNextFirstResult() doesn't return a value equal or greater than the
resultCount.
Isnt't this the expected behavior for you guys?
