    eclipse dev mode console:
    "WARN:ButtonItem:isc_ButtonItem_2:CanvasItem: isc_ButtonItem_1 defined with no canvas property - creating a default canvas for this item."

    *** Sample Code ***
    Sorry I did not test this in isolated mode, but i assume the problem is straightforward enough. Here's a sample of the code.

    Exeption is thrown when the following code is executed:
    SearchForm searchForm = new SearchForm();
    vLayout.addMember(searchForm);

    public class WorkItemSearchForm extends SearchForm {
    ButtonItem button = new ButtonItem();
    TextItem query = new TextItem();

    public WorkItemSearchForm() {
    SearchForm form = this;
    form.setNumCols(3);
    form.setWidth(150);

    query.setName("searchDesc");
    query.setTitle("Search Description");
    query.setDefaultValue("");

    button.setTitle("Search");
    button.setStartRow(false);

    form.setItems(query, button);
    }
    ...
    }

    FYI - also having similar problem with RichTextItem (works when i substitute TextAreaItem) when upgrading from SmartGWT LGPL 2.2, sample code below:

    DynamicForm form = new DynamicForm();
    DataSource ds = DummyDataSource.getInstance();
    RichTextItem templateEdit = new RichTextItem("Template", "Waiting for server");
    ds.getField("Template").setEditorType(templateEdit);
    form.setDataSource(ds);

    error msg:
    13:43:06.443 [ERROR] [jsonclient] 13:43:06.380:WARN:RichTextItem:isc_RichTextItem_1:CanvasItem: Template defined with no canvas property - creating a default canvas for this item.
