Problem when removing elements from table after apply sort

Question

Hi,
I have big problem with <af:table> and sorting.
When I removed objects from a table without sorting, there is no problem but when I removed
items from the table after sorting, the remain items are not correct.
For example, i have in my table these items :
Item AA
Item CC
Item ZZ
Item BB
Item AA
Item BB
Item CC
Item ZZ
I sort the table and i select the following Items : Item BB a Item CC
The remains item is only Item AA, Item ZZ disappear.
If i resort the table, the missing Item zz appear again in the table.
Here is my jspx :
<af:table var="row" rowBandingInterval="1" width="1050" rows="5"
rowSelection="multiple"
value="#{pageFlowScope.editNotificationBackingBean.ingredients}"
binding="#{pageFlowScope.editNotificationBackingBean.ingredientsTable}"
autoHeightRows="10" id="t2">
<af:clientListener method="goEditRow" type="dblClick"/>
<af:serverListener type="doubleClickOnRow" method="#{pageFlowScope.editNotificationBackingBean.handleRequestIngredientsSelectBtn_action}"/>
<af:column headerText="#{bundle.col_fr_name}" width="240"
sortable="true" sortProperty="name.FR_Description" id="c1">
<af:outputText value="#{row.name.texts['fr'].value}" id="ot1"/>
</af:column>
In my backing bean i call this method to remove selected elements :
public void unselectBtn_action(ActionEvent actionEvent) {
RowKeySet rowKeySet = selectIngredientsTable.getSelectedRowKeys();
int i = 0;
Iterator it = rowKeySet.iterator();
while (it.hasNext()) {
     Integer index = (Integer)it.next() - i;
selectIngredientsTable.setRowKey(index);
CompositionIngredient compositionIngredient =
(CompositionIngredient)selectIngredientsTable.getRowData();
notification.getProductDetail().getCompositionIngredients().remove(compositionIngredient);
i++;
selectIngredientsTable.getSelectedRowKeys().clear();
AdfFacesContext.getCurrentInstance().addPartialTarget(selectIngredientsTable);
Thanks in advance.

I have made a mistake, i don't paste the right <af:table> from my jspx.
Here is the correct one :
<af:table var="row" rowBandingInterval="1" width="1050"
rowSelection="multiple" id="tableSelectedIngredients"
value="#{pageFlowScope.editNotificationBackingBean.notification.productDetail.compositionIngredients}"
binding="#{pageFlowScope.editNotificationBackingBean.selectIngredientsTable}"
partialTriggers="::tab_ingredients_list_expressed_per">
<af:column sortable="true" headerText="#{bundle.col_name}" id="c5" width="180"
sortProperty="ingredient.name.FR_Description">
<af:outputText value="#{row.ingredient.name.texts['fr'].value}"
id="ot18"/>
</af:column>
