Exception when using setEditorType in DataSource

[thiebal]

Hi,

I'm using fields from a DataSource for a DynamicForm but I want to use a TextAreaItem instead of a TextItem for a field. So I use the setEditorType method in the DataSource but it generates an exception:

Uncaught JavaScript exception [com.google.gwt.core.client.JavaScriptException: (TypeError): Object expected
 number: -2146823281
 description: Object expected
    at com.smartgwt.client.util.JSOHelper.setAttribute(Native Method)
    at com.smartgwt.client.widgets.BaseWidget.getOrCreateJsObj(BaseWidget.java:319)
    at com.smartgwt.client.widgets.form.DynamicForm.fetchData(Native Method)

Form

DynamicForm form = new DynamicForm();
form.setDataSource(DataSchemaDS.getInstance());

DataSource

public DataSchemaDS(String identifier) {
  setID(identifier);
  DataSourceTextField name = new DataSourceTextField("name", "Name");
  name.setPrimaryKey(true);
  name.setRequired(true);
  addField(name);

  DataSourceTextField description = new DataSourceTextField("description", "Description");
  description.setEditorType(new TextAreaItem());
  addField(description);
}

I'm using the latest SVN version.
Any ideas ?

Thanks
