    NPE in ExtendedDataTable

    Serhiy Zastavnyy Novice

      Hello

      I had NPE when trying to group by column.
      May be you could check this in sources.
      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.
