             Summary: HTML input placeholder text breaks AutoCompleteTextField in IE11
                 Key: WICKET-5959
                 URL: https://issues.apache.org/jira/browse/WICKET-5959
             Project: Wicket
          Issue Type: Bug
          Components: wicket-extensions
    Affects Versions: 6.20.0
         Environment: Windows 8.1 + Internet Explorer 11
            Reporter: Remy Kaufmann


Reproduction steps are provided below:

1. Configure an AutoCompleteTextField so that the suggestion list shows on focus gain, and shows even if the input is still empty.
2. Link the AutoCompleteTextField to an HTML input element that has a value assigned to its "placeholder" attribute.
3. Embed the AutoCompleteTextField on a webpage, and open the webpage in Internet Explorer 11.
4. Click on the HTML input so that it receives focus. Do not type any text.
5. Click on an item from the AutoComplete dropdown list. Observe that nothing happens.

Opening the console reveals that an error has occurred in the "getSelectedValue()" function in the "wicket-autocomplete.js" file. The error is caused by the fact that the variable "selected" has a value of "-1", which causes the "getSelectableElement(selected)" call to go wrong and return "undefined".

I have recreated the issue in a Quickstart.
