IndicatingAjaxButton works only once <p>I have derived a class from IndicatingAjaxButton (which is the button to a form). But the IAjaxIndicatorAware does only work once, i.e. if the validation of the form fails I print feedback messages within the form. During the 1st request the "onProgress-Circle" is shown. But if I click on the button again (after I made the right input on the form), there is no "onProgress-Circle" anymore. </p> <p>I took a look in the generated HTML: 1) Before the first click, there is a img tag, which gets displayed when the request is started 2) After the first request is processed, this img tag is removed. </p> <p>This are the evaluation steps that are returned from the server:</p> <pre><code>&lt;evaluate&gt;&lt;![CDATA[var e = Wicket.$('previouse--ajax-indicator'); if (e != null &amp;&amp; typeof(e.parentNode) != 'undefined') e.parentNode.removeChild(e);]]&gt;&lt;/evaluate&gt; </code></pre> <p>This I guess leads to removing all childs from the button, also the img tag. Is this a bug or do I use the button in a wrong way?</p> <p>I use Wicket 1.5</p> <p>Thanks and kind regards, Soccertrash</p>
