[BUG] Error while accessing hidden FormItem after the Form is drawn

[andy.2003]

Hello,

with the 3.1p 2013/01/28 LGPL I get an error, if I try to access a hidden FormItem after the Form is drawn. Here is the TestCase:

        DataSource ds = new DataSource();
        DataSourceField foo = new DataSourceField("foo", FieldType.TEXT);
        foo.setHidden(true);
        ds.setFields(foo);

        final DynamicForm form = new DynamicForm();
        form.setDataSource(ds);
        form.setUseAllDataSourceFields(true);
        form.setFields(new FormItem("foo"));
        System.out.println(form.getField("foo")); // WORKS
        form.draw();
        System.out.println(form.getField("foo")); // ERROR

and here is the error from the GWT-Console:

 	com.google.gwt.core.client.JavaScriptException: (TypeError): self is null
 	at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:248)
