Selecting initial rows CoreTable

Question

I have a <tr:table value="#{mybean.tableValue} binding="#{mybean.tableBinding}"> that i want to show with the selection multiple enabled. I'm using a List for the collection and the values are take from database when i selected a value from a <tr:selectManyCheckbox> valueChangeListener with partial triggers.

For each row returned, if some value is true, i want this row marked as selected in the <tr:table value="#{mybean.tableValue} binding="#{mybean.tableBinding}">

I think the problem is that my binding value is not updating when the valueChangeEvent runs inspite of i put binding.setValue the results of database (i checked that the binding.getRowCount() not equal than mybean.tableValue.size()) and then the values selected are not correct)

Any idea why the binding rowCount is not equal the value of table?

UPDATE:

<tr:subform id="subform1">
    <tr:panelFormLayout rows="6">
    <tr:selectManyCheckbox id="val1" label="Values"
      layout="horizontal" value="#{mybean.data1Values}" 
      autoSubmit="true" valueChangeListener="#{mybean.valuesChangeListener}">
        <f:selectItems value="#{mybean.list1Values}"/>
    </tr:selectManyCheckbox>                        
   </tr:panelFormLayout>
</tr:subform>
<tr:spacer width="5px"/>
<tr:subform id="subform2">            
    <tr:table rows="0" partialTriggers=":::subform1:val1 " 
      value="#{mybean.data2Values}" var="item" id="tabladatos" width="75%" 
      rowSelection="multiple" rowBandingInterval="1" binding="#{mybena.tableBinding}"
      verticalGridVisible="true" horizontalGridVisible="true">
    <tr:column id="_head1" headerText="Colum1" width="30%">
        <tr:outputText id="_head1_value" value="#{item.value1}"/>
    </tr:column>
    <tr:column id="_head2" headerText="Colum2" width="30%">
        <tr:outputText id="_head2_value" value="#{item.value2}"/>
    </tr:column>                
    </tr:table>        
</tr:subform>

public void valuesChangeListener(ValueChangeEvent event) {
        if (event != null) {
            List<Integer> valores = (List<Integer>) event.getNewValue();
            data2Values.addAll(databaseDAO.search(valores));
            RowKeySet rks = new RowKeySetImpl();
            rks.clear();
            tableBinding.setSelectedRowKeys(rks);
            tableBinding.setValue(data2Values);
            for (int x = 0; x < tableBinding.getRowCount(); x++) {
                dataEntity row = (dataEntity) tableBinding.getRowData(x);
                tableBinding.setRowIndex(x);
                if (row.isTrue()) {
                    Object key = tableBinding.getRowKey();
                    rks.add(key);//tableBinding.getSelectedRowKeys().add(key);
                } else {
                    //do something
                }
            }
            tableBinding.setVar("item");
            tableBinding.setSelectedRowKeys(rks);
            FacesContext context = FacesContext.getCurrentInstance();
            context.renderResponse();
        }

    }    

Thanks!

Solved! I changed the valueChangeListener:

public void valuesChangeListener(ValueChangeEvent event) {
        if (event != null) {
            List<Integer> valores = (List<Integer>) event.getNewValue();
            data2Values.addAll(databaseDAO.search(valores));
            tableBinding.getSelectedRowKeys().clear;
            tableBinding.setValue(data2Values);
            for (int x = 0; x < tableBinding.getRowCount(); x++) {
                dataEntity row = (dataEntity) tableBinding.getRowData(x);
                tableBinding.setRowIndex(x);
                Object key = tableBinding.getRowKey();
                if (row.isTrue()) {                    
                    tableBinding.getSelectedRowKeys().add(key);
                } else {
                    tableBinding.getSelectedRowKeys().remove(key);
                }
            }
            tableBinding.setVar("item");
            FacesContext context = FacesContext.getCurrentInstance();
            context.renderResponse();
        }

    }
