使用具有通过小门1.4退出时更新模型的功能在listView中添加TextField

Question

I'm trying to add TextField in a listView that can update a model on exit or after update the text on it.

I have received a wonderful solution for this listed bellow but it seems works in wicket 6.7.0, I guess?

import org.apache.wicket.ajax.attributes.{ThrottlingSettings, AjaxRequestAttributes}


 val detail = new TextField("detail", new PropertyModel[Meeting](meeting, "description"))
      detail.add(new AjaxFormComponentUpdatingBehavior(("keyup")) {
        protected def onUpdate(target: AjaxRequestTarget) {
          meeting.salvarMeetingInfo(meeting)
        }

        protected override def updateAjaxAttributes(attributes: AjaxRequestAttributes) {
          attributes.setThrottlingSettings(new ThrottlingSettings("thr", Duration.milliseconds(800.0)))
          super.updateAjaxAttributes(attributes)
        }
})
item.add(detail)

//Error messages
      scala: object attributes is not a member of package org.apache.wicket.ajax
import org.apache.wicket.ajax.attributes.{ThrottlingSettings, AjaxRequestAttributes}

                              ^

scala: not found: type AjaxRequestAttributes
        protected override def updateAjaxAttributes(attributes: AjaxRequestAttributes) {
                                                            ^

But I need to use wicket 1.4, so there is an similar implementation or solution of the code above for wicket 1.4?

Thanks for someone that could help me.

There is no updateAjaxAttributes method in 1.4 call method setThrottleDelay on the behaviour instead. See docs for the details.
