Issue with value of transient attribute after filtering or sorting a table

Question

Hi guys,
  i'm using jdev 11.1.1.4.0 .
  i've the use case :
         - a table with a column containing a checkbox to mark the selection of  a row
<af:column align="center" sortProperty="TemIsChosen" filterable="true"
sortable="true" id="c6">
<af:selectBooleanCheckbox value="#{row.bindings.TemIsChosen.inputValue}" autoSubmit="true"
shortDesc="#{bindings.ServersIndicTempVVO.hints.TemIsChosen.tooltip}"
id="sbc1"
valueChangeListener="#{backing_initIndicatorsTemp.onSelectTemp}"/>
</af:column>
         - i select one or more rows with checkboxes
         - if i filter  or sort the table, the selection of the checkboxes reset to not selected (value false by default).
     I understand that for the framework, it's a normal behavior because for filtering or sorting , it re-executes the query from database. And transient attribute is not persistent, so it goes back to the default initial value "false".
     What i would appreciate, it's that filtering or sorting has no effect on the value of the transient attribute, ie end user selection remains.
      I tried to modify query mode of the ViewObject to filter with in-memory data. It works fine but if you reset filter inputs you can't retrieve correct RowSet. Only new RowSet is stored, old is lost.
       So  now it's the filtering feature that doesn't work as expected.
   How can i implement  my use case withouth the troubles i've described.
Best regards,
David

Hi Frank,
   no it's a view object level attribute inside a read-only view object.
  The view object doesn't use any entity.
  Here is the definition of the attribute in the xml file of the VO, if can help you :
<ViewAttribute
    Name="TemIsChosen"
    IsSelected="false"
    IsPersistent="false"
    PrecisionRule="true"
    Type="java.lang.Boolean"
    ColumnType="BIT"
    AliasName="VIEW_ATTR"
    SQLType="BIT"
    Passivate="true">
    <Properties>
      <SchemaBasedProperties>
        <TOOLTIP
          ResId="ADD"/>
        <DISPLAYWIDTH
          Value="50"/>
      </SchemaBasedProperties>
    </Properties>
  </ViewAttribute>
