[BUG] ListGridField with value-aware CanvasItem throws Exception in storeValue

[andy.2003]

Hello,

I'm using smartgwt LGPL 3.1p 20130530 (nightly).
When using a custom CanvasItem, which stores its value via CanvasItem::storeValue(), I get the following error after changing the value of the item:

Uncaught exception escaped : com.google.gwt.event.shared.UmbrellaException
Exception caught: Exception caught: (TypeError) @com.smartgwt.client.widgets.form.fields.CanvasItem::storeValue(Ljava/lang/Object;)([string: '4567897']): self.storeValue is not a function

this is the code for reproducing the error:

public void onModuleLoad() {
	ListGrid lg = new ListGrid();
	lg.setWidth100();
	lg.setHeight100();
	lg.setEditorCustomizer(new ListGridEditorCustomizer() {
		@Override
		public FormItem getEditor(ListGridEditorContext context) {
			if ("foo".equals(context.getEditField().getName())) {
				return new CanvasItem() {
					{
						setShouldSaveValue(true);
						TextArea input = new TextArea();
						setCanvas(new WidgetCanvas(input));
						input.addValueChangeHandler(new ValueChangeHandler<String>() {
							@Override
							public void onValueChange(ValueChangeEvent<String> event) {
								// self.storeValue is not a function
								storeValue(event.getValue());
							}
						});
					}
				};
			}
			return context.getDefaultProperties();
		}
	});
	lg.setFields(new ListGridField("foo"), new ListGridField("bar"));
	lg.startEditingNew();
	lg.setCanEdit(true);
	lg.draw();
}

regards
Andreas

Like DataSourceField.setEditorType(), returning a FormItem via this customizer has special rules - you need to get the CanvasItem instance from the event rather than relying on the one that's implicitly in scope as "this".

Hello, there is no event with an attached CanvasItem. Can you give an example of what you mean.
