Extending EntityQuery in seam 2.0.1 GA is not working properly. For some reason, the 'firstResult' is not injected by default and isNextExists() method always return false. The solution i found was to override both setFirstResult() and isNextExists() method. I manually injected the firstResult request context parameter, created an implementation of isNextExists() and everything seems to be working. Here is my EntityQuery subclass:

@Name("userList")
public class UserList extends EntityQuery {

private static final long serialVersionUID = 4676553441988735518L;

public UserList() {
setMaxResults(2);
}

@Override
public String getEjbql() {
return "select user from User user";
}

@RequestParameter("firstResult")
@Override
public void setFirstResult(Integer firstResult) {
if(firstResult==null) {
firstResult = 0;
}
super.setFirstResult(firstResult);
}

@Override
public boolean isNextExists() {
if(getFirstResult() + getMaxResults() < getResultCount()) {
return true;
}
return false;
}
}

And my xhtml code:

<s:link view="/userList.xhtml" value="Previous" rendered="#{userList.previousExists}">
<f:param value="#{userList.previousFirstResult}" name="firstResult" />
</s:link>

<s:link view="/userList.xhtml" value="Next" rendered="#{userList.nextExists}">
<f:param value="#{userList.nextFirstResult}" name="firstResult" />
</s:link>
