Cascading LOV in af:table will not refresh correctly

Question

Jdeveloper version 11.1.1.5.0
I have spent quite a bit of time trying to understand why 2-level cascading LOV won't work in a particular situaion. I still haven't been able to fix it and so I turn to the ADF gurus on this forum.
Here's the scenario:
1. I have a ViewObject called AdjustDeltaValuesView. This VO contains attributes from its entity. It also has transient attributes called CategoryId and CodeId.
2. There is LOV defined for CategoryId for VO CodeCategoryMasterView
3. There is LOV defined for CodeId for LimitedCodeMasterView.
3. View Criteria is created for LimitedCodeMasterView which sets a bind variable value from CodeCategoryMasterView.CodeCategoryId.
4. I have wired all the LOVs correctly and it is working properly in ADF BC tester.
5. In the UI, I have dropped AdjustDeltaValuesView data control as ADF Table where CategoryId and CodeId are displaying as af:selectOneChoice.
6. CategoryId has autoSubmit=true and CodeId has partialTrigger set to component ID of CategoryId.
7. The LOV inside editable af:table is working fine except one scenario that when user selects same categoryId from the category LOV in the second row, the CodeId LOV will not populate.
Here's the code snippet of jspx:
        <af:table value="#{bindings.AdjustDeltaValuesView1.collectionModel}"
                  var="row" rows="#{bindings.AdjustDeltaValuesView1.rangeSize}"
                  emptyText="#{bindings.AdjustDeltaValuesView1.viewable ? 'No data to display.' : 'Access Denied.'}"
                  fetchSize="#{bindings.AdjustDeltaValuesView1.rangeSize}"
                  rowBandingInterval="0"
                  selectedRowKeys="#{bindings.AdjustDeltaValuesView1.collectionModel.selectedRow}"
                  selectionListener="#{bindings.AdjustDeltaValuesView1.collectionModel.makeCurrent}"
                  rowSelection="single" id="t1" editingMode="editAll"
                  rendered="false">
          <af:column sortProperty="CategoryId" sortable="false"
                     headerText="#{bindings.AdjustDeltaValuesView11.hints.CategoryId.label}"
                     id="c25">
            <af:selectOneChoice value="#{row.bindings.CategoryId.inputValue}"
                                label="#{row.bindings.CategoryId.label}"
                                required="#{bindings.AdjustDeltaValuesView11.hints.CategoryId.mandatory}"
                                shortDesc="#{bindings.AdjustDeltaValuesView11.hints.CategoryId.tooltip}"
                                id="soc3" autoSubmit="true">
              <f:selectItems value="#{row.bindings.CategoryId.items}" id="si3"/>
            </af:selectOneChoice>
          </af:column>
          <af:column sortProperty="CodeId" sortable="false"
                     headerText="#{bindings.AdjustDeltaValuesView11.hints.CodeId.label}"
                     id="c27">
            <af:selectOneChoice value="#{row.bindings.CodeId.inputValue}"
                                label="#{row.bindings.CodeId.label}"
                                required="#{bindings.AdjustDeltaValuesView11.hints.CodeId.mandatory}"
                                shortDesc="#{bindings.AdjustDeltaValuesView11.hints.CodeId.tooltip}"
                                id="soc4" partialTriggers="soc3">
              <f:selectItems value="#{row.bindings.CodeId.items}" id="si4"/>
            </af:selectOneChoice>
          </af:column>For example, where it DOES NOT Work
1. User selects Category A from dropdown from the first row.
2. code Id dropdown populates with corresponding values in the list based on CategoryId user selected.
3. user selects Code X from the dropdown.
4. User selects Category A from the dropdown from the second row.
5. PROBLEM: In the second row, Code Id dropdown does not populate. Code dropdown is empty.
Where it works:
1. User selects Category A from dropdown from the first row.
2. code Id dropdown populates with corresponding values in the list based on CategoryId user selected.
3. User selects Category A from the dropdown from the second row.
4. In the second row, Code Id dropdown populates correctly.
Where it works:
1. User selects Category A from dropdown from the first row.
2. code Id dropdown populates with corresponding values in the list based on CategoryId user selected.
3. user selects Code X from the dropdown.
4. User selects Category B from the dropdown from the second row.
5. In the second row, Code Id dropdown populates correctly.
Has anyone come across this scenario? It's a very weird problem.
I hope I have explained this well. If it's not clear please let me know.

Hi,
Always mention your JDev version.
Try modifying your VOs as explained in this blog and see if it works fine : https://blogs.oracle.com/aramamoo/entry/how_to_create_multi_level
