Description

Suppose I have BlinkBehaviour

public static class BlinkBehaviour extends Behavior {
@Override
public void renderHead(Component component, IHeaderResponse response) {
AjaxRequestTarget target = component.getRequestCycle().find(AjaxRequestTarget.class);
if (target != null)

{ target.prependJavaScript("notify|jQuery('#" + component.getMarkupId() + "').fadeOut(400, notify);"); target.appendJavaScript("jQuery('#"+component.getMarkupId()+"').fadeIn(400);"); }

}
}

If I add it twice to a control and update the control via ajax 6.7.0-SNAPSHOT will yield error:

ERROR: Wicket.Ajax.Call.processEvaluation: Exception evaluating javascript: SyntaxError: Unexpected token ), text: f = function(notify)

{jQuery('#version2').fadeOut(400, notify);}

)();(function()

{notify|jQuery('#version2').fadeOut(400, notify);}

;
