Has something changed with the wave recently. A robot that I have,
inserts a form button. After that button has been clicked, the robot
deletes that button and adds another. Here is a code snippet:
// Remove start presentation button
ref = event.getBlip().first(ElementType.BUTTON,
Restriction.of(FormElement.NAME, FormAction.StartPresentation));
if (ref.value().asElement().isFormElement())
{
ref.delete();
}
//add syndication button
FormElement formElement = new FormElement(ElementType.BUTTON,
FormAction.SyndicatePresentation, "Syndicate Presentation");
event.getBlip().append(formElement);
It is bombing out on the ref.delete() call. It wasn't doing this
before. Any help would be appreciated.
