MDS persistence for column within a loop

Question

Hello,
I am trying out basic setup of MDS. I was able to make it work for most of my columns except for a column within a loop. I also tried using the ADF Read Only Dynamic table and it is not persisting any of the columns of the table, since it is inside the loop.
I would like to know if this is a bug when you apply MDS to component that has id that is dynamically incremented/generated.
mds customization file - c18 i s missing which should correspond to the dynamic column
<?xml version = '1.0' encoding = 'UTF-8'?>
<mds:customization version="11.1.1.60.13" xmlns:mds="http://xmlns.oracle.com/mds">
<mds:modify element="c17">
<mds:attribute name="displayIndex" value="1"/>
</mds:modify>
<mds:modify element="c21">
<mds:attribute name="displayIndex" value="2"/>
</mds:modify>
<mds:modify element="c16">
<mds:attribute name="displayIndex" value="3"/>
</mds:modify>
<mds:modify element="c20">
<mds:attribute name="displayIndex" value="4"/>
</mds:modify>
<mds:modify element="c19">
<mds:attribute name="displayIndex" value="5"/>
</mds:modify>
<mds:modify element="c28">
<mds:attribute name="displayIndex" value="6"/>
</mds:modify>
<mds:modify element="c27">
<mds:attribute name="displayIndex" value="11"/>
</mds:modify>
<mds:modify element="c22">
<mds:attribute name="displayIndex" value="12"/>
</mds:modify>
<mds:modify element="c15">
<mds:attribute name="displayIndex" value="0"/>
</mds:modify>
</mds:customization>
jspx related to the display, just to show the component id. In blue is the logic/code for dynamically displaying a column and the dropdown and contents of the dropdown
<af:forEach
items="#{pageFlowScope.SearchRules.filterBeans}" varStatus="index" var="def">
*<af:column id="c18" headerText="#{def.parameterDisplayName}">*
<af:selectOneChoice value="#{row.dataProvider.ruleColumns[index.index].attributeId}"
disabled="#{!(sessionScope.usersession.ruleAuth.isRoleForCreateEditRule and row.dataProvider.ruleColumns[index.index].isEdit)}"
clientComponent="true"
helpTopicId="#{row.dataProvider.ruleColumns[index.index].ruleTypeParameterID}"
autoSubmit="true" shortDesc="#{row.message}"
id="soc4445" valuePassThru="true"
valueChangeListener="#{pageFlowScope.SearchRules.ccsChange}">
<af:forEach items="#{bindings.Rule.rangeSet}" varStatus="att" >
<af:selectItem label="#{row.dataProvider.ruleColumns[index.index].attributes[att.index].assignedAttributeValue}"
value="#{row.dataProvider.ruleColumns[index.index].attributes[att.index].assignedAttributeID}"
rendered="#{row.dataProvider.ruleColumns[index.index].attributeSize > att.index}"
id="si4"/>
</af:forEach>
<!--f:selectItems value="#{row.dataProvider.ruleColumns[index.index].attributes}"
id="si4"/-->
</af:selectOneChoice>
</af:column>
</af:forEach>
Thanks,

Hi,
the problem actually is that the id is the same for all of the occurences. So the forEach loop should create unique IDs for each occurence of a component.
