Iterator does not iterate

Question

Dear all,
I have the following problem:
I have a table with behind it a iterator. The data behind the table contains 12 rows. The table's rangesize gets initiated at 10 and the first time the table is shown it shows 10 filled rows.
However:
If I click on the 'next 2' or I select the '11-12' option on the dropdownlist of the table, the table shows 10 rows, starting from the 3th row of the previous set and ending with two blank rows.
The normal behavior, of other tables in the same application, is showing the next two rows in a refreshed table of two rows, this particular table seems not to have that intention.
I presume that the iterator, for some strange reason, doesn't change to the next row set.
It doesn't update the correct range nor rangestart in stead it uses the old rangesize (10), wants to show the two last rows but doesn't (blank rows).
Could anyone give me a hand on this ?
Some code:
the table:
<af:table value="#{bindings.ViewsLvl1AppModule1BalancesRefMovResultView.collectionModel}"
var="row"
rows="#{bindings.ViewsLvl1AppModule1BalancesRefMovResultView.rangeSize}"
emptyText="#{bindings.ViewsLvl1AppModule1BalancesRefMovResultView.viewable ? 'No rows yet.' : 'Access Denied.'}"
banding="row"
width="100%"
binding="#{instrumentDetailsBean.coreTable}">
From the pagedef:
<iterator id="BalancesRefMovResultViewIterator" RangeSize="10"
Binds="Root.ViewsLvl1AppModule1.BalancesRefMovResultView"
DataControl="GlobalAppModuleDataControl"
RefreshCondition="#{instrumentDetailsBean.queryExecuted}"/>
and
<table id="ViewsLvl1AppModule1BalancesRefMovResultView"
IterBinding="BalancesRefMovResultViewIterator">
<AttrNames>
<Item Value="DatCreation"/>
<Item Value="NbrMvt"/>
<Item Value="AmtOper"/>
<Item Value="TypMvt"/>
<Item Value="StopCodStop"/>
<Item Value="DscStop"/>
<Item Value="RefCik"/>
<Item Value="AccnNbrAcc"/>
<Item Value="CodStop"/>
<Item Value="DemdNbrDemand"/>
<Item Value="NamShort"/>
<Item Value="NamFullPrim"/>
<Item Value="RefAff"/>
</AttrNames>
</table>
If I on the other hand use a self-made dropdownlist that changes the range manually, the range and the table and, hurray, the last two rows, get displayed like a charm.
from the bean:
public void setRangeSize(Integer rangeSize) {
if(rangeSize == null)
return;
coreTable.setRows(rangeSize.intValue());
coreTable.setShowAll(false);
this.rangeSize = rangeSize;
EL.modifyRangeInIteratorBinding(this.rangeSize, "BalancesRefMovResultViewIterator");
from 'EL':
public static void modifyRangeInIteratorBinding(int range, String name) {
DCIteratorBinding iterBinding = getIteratorBinding(name);
if (iterBinding!=null){
iterBinding.setRangeSize(range);
} else {
log.error("faulty iteratorbinding occured in modifyRangeInIteratorBinding:"+name);
Any help or pointers to help greatly appreciated.
S.
Also: I tried to mimic the default behaviour by hand but it doesn't work, I attached a rangeChangeEventListener:
public void changeRangeEvent(RangeChangeEvent rangeChangeEvent) {
EL.modifyRangeStartInIteratorBinding(rangeChangeEvent.getNewStart(),"BalancesRefMovResultViewIterator");
setRangeSize(rangeChangeEvent.getNewEnd()-rangeChangeEvent.getNewStart()+1);
with again 'EL':
public static void modifyRangeStartInIteratorBinding(int rangeStart, String name) {
DCIteratorBinding iterBinding = getIteratorBinding(name);
if (iterBinding!=null){
iterBinding.setRangeStart(rangeStart);
} else {
log.error("faulty iteratorbinding occured in modifyRangeStartInIteratorBinding:"+name);
But when this code is executed the rangestart stays on 0 (only the first rows are displayed).
grtz,
S.

Hi,
which Model technology is your application based on ?
ADF Business Components ?
The View Objects have a property called "*Fill Last Page of Rows when Paging Through Rowset*" (in the VO Editor wizard, "*Tuning*").
From the online help:
When a user scrolls through data in a page-by-page fashion on a client (such as from a series of web pages), the default behavior is to completely fill the last page with data.
As a result, rows viewed on the previous page can appear on the last page. Select to maintain this default behavior.

Didier.
