Description

The following processing sequence leads to a JavaScript error:

• form is shown including an autoCompleteTextField
• user enters criteria and immediately presses enter
• actualUpdateChoices() is scheduled by the throttler
• form is submitted via ajax
• autoCompleteTextField is removed from DOM
• throttler executes actualUpdateChoices()
• wicket-autocomplete fails with precondition, since element is no longer in DOM:

var elementVal = Wicket.$(elementId).value;
