ListGrid/ListGridField.setCellFormatter(null)

[atomatom]

I wanted to be able to set a cellFormatter and then remove it, enabling the default formatting again. setCellFormatter does not let you do this and blows up when you pass it a null. This is the current code:

  public native void setCellFormatter(CellFormatter formatter) /*-{
            var self = this.@com.smartgwt.client.core.DataClass::getJsObj()();
            self.formatCellValue = $debox($entry(function(value, record, rowNum, colNum) {
                var recordJ = @com.smartgwt.client.widgets.grid.ListGridRecord::getOrCreateRef(Lcom/google/gwt/core/client/JavaScriptObject;)(record);
                var valueJ = $wnd.SmartGWT.convertToJavaType(value);
                return formatter.@com.smartgwt.client.widgets.grid.CellFormatter::format(Ljava/lang/Object;Lcom/smartgwt/client/widgets/grid/ListGridRecord;II)(valueJ, recordJ, rowNum, colNum);
            }));
    }-*/;

I think this could easily be fixed with

  public native void setCellFormatter(CellFormatter formatter) /*-{
            var self = this.@com.smartgwt.client.core.DataClass::getJsObj()();[b]
            if (formatter==null)
              self.formatCellValue = null;
            else[/b]        
            self.formatCellValue = $debox($entry(function(value, record, rowNum, colNum) {
                var recordJ = @com.smartgwt.client.widgets.grid.ListGridRecord::getOrCreateRef(Lcom/google/gwt/core/client/JavaScriptObject;)(record);
                var valueJ = $wnd.SmartGWT.convertToJavaType(value);
                return formatter.@com.smartgwt.client.widgets.grid.CellFormatter::format(Ljava/lang/Object;Lcom/smartgwt/client/widgets/grid/ListGridRecord;II)(valueJ, recordJ, rowNum, colNum);
            }));
    }-*/;

A workaround is to call

  ListGridField.setAttribute("formatCellValue",(String)null);
