      Hello

      I have column with boolean expression and show picture there according to value.

            I just added to my ExtendedDataTable column like this:

            

 src = "#{item.booleanValue ? '" + "/images/yes.png" + " ' : ' "+"/images/no.png" + "'}";

 HtmlColumn col = new HtmlColumn();

 col.setId(id);

 col.getChildren().add( getGraphicImage(src) );

 col.setHeaderClass("dataTableHeader");
 col.getFacets().put("header", header);

 col.setWidth(width);

 ValueExpression exp = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
 createValueExpression(FacesContext.getCurrentInstance().getELContext(), src, String.class);

 col.setSelfSorted(true);
 col.setValueExpression("sortBy", exp);






 public static UIComponent getGraphicImage(String src){

 HtmlGraphicImage x = new HtmlGraphicImage();

 x.setValueExpression("value", FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
 createValueExpression(FacesContext.getCurrentInstance().getELContext(), src, String.class));


 return x;
 }


            Sorting works fine, but when I tried to group data by this column - I had NPE.
