How to hide row from table after logical delete

Question

Hello.
I am using Jdeveloper 11.1.1.3.0, ADF BC and ADF Faces.
I want to implement Logical delete in my application.
In my Entity object I have Deleted attribute and I override the remove() method in my EntityImpl class.
    @Override
    public void remove()
       setDeleted("Y");
    }and I added this condition to my view object
WHERE NVL(Deleted,'N') <> 'Y'in my page I have a table. this table has a column to delete each row. I dragged and drop RemoveRowWithKey action from the data control
and set the parameter to *#{row.rowKeyStr}* .
I what I need is this:
when the user click the delete button I want to hide the roe from the table. I tried to re-execute the query after the delete but the row is still on the page. Why execute query does not hide the row from the screen.
here is the code I used for delete and execute query
    public String deleteLogically()
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding = bindings.getOperationBinding("removeRowWithKey");
        Object result = operationBinding.execute();
        DCBindingContainer dc=(DCBindingContainer) bindings;
        DCIteratorBinding iter=dc.findIteratorBinding("TakenMaterialsView4Iterator");
        iter.getCurrentRow().setAttribute("Deleted", "Y");
        //iter.getViewObject().executeQuery();
        iter.executeQuery();
        return null;
    }as you see I used two method iter.getViewObject().executeQuery(); and  iter.executeQuery(); but the result is same.

Thank you Jobinesh.
I used this method.
    @Override
    protected boolean rowQualifies(ViewRowImpl viewRowImpl)
      Object attrValue =viewRowImpl.getAttribute("Deleted"); 
        if (attrValue != null) { 
         if ("Y".equals(attrValue)) 
            return false; 
         else 
            return true; 
        return super.rowQualifies(viewRowImpl);
    }But I have one drawback for using it, and here is the case:
If the user clicks the delete button *(no commit)* the row will be hidden in the table, but when the user click cancel changes the row is not returned since it is not returned due to the rowQualifies(ViewRowImpl viewRowImpl) (the Deleted attribute is set to "N" now).
here is the code for delete and cancel change buttons
    public String deleteLogically()
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding =
            bindings.getOperationBinding("removeRowWithKey");
        Object result = operationBinding.execute();
        DCBindingContainer dc = (DCBindingContainer)bindings;
        DCIteratorBinding iter =
            dc.findIteratorBinding("TakenMaterialsView4Iterator");
        iter.getCurrentRow().setAttribute("Deleted", "Y");
         iter.executeQuery();
        AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
        adfFacesContext.addPartialTarget(this.getTakenMaterialsTable());
        return null;
    public String cancelChanges(String iteratorName)
        System.out.println("begin cancel change");
        BindingContainer bindings =
            BindingContext.getCurrent().getCurrentBindingsEntry();
        DCBindingContainer dc = (DCBindingContainer)bindings;
        DCIteratorBinding iter =
            (DCIteratorBinding)dc.findIteratorBinding(iteratorName);
        ViewObject vo = iter.getViewObject();
        //create a secondary RowSetIterator to avoid disturbing row currency
        RowSetIterator rsi = vo.createRowSetIterator(null);
        //move the currency to the slot before the first row.
        rsi.reset();
        while (rsi.hasNext())
                currentRow = rsi.next();
                currentRow.setAttribute("Deleted", "N");
        rsi.closeRowSetIterator();
        iter.executeQuery();
        AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
        adfFacesContext.addPartialTarget(this.getTakenMaterialsTable());
        return null;
    }as example, if the user initially has 8 rows, then deleted 2 rows, in cancelChanges only 6 rows appears. and the deleted rows are not there??
any suggestion?
