Only problem is that it is not working. The panels never update to the new panels. I can see that the onEvent fires as the javascript alert is shown. But the javascript is only shown the first time I click a link. After the first click, all the links call their onClick method and send the event out but the event is never picked up. Does every panel need to have its own onEvent method to listen for the events.
If so, I think the old method of handling ajax is going to be easier. -----Original Message----- From: Igor Vaynberg [mailto:igor.vaynb...@gmail.com] Sent: Wednesday, March 28, 2012 3:49 PM To: users@wicket.apache.org Subject: Re: Event handling and swapping panels that is correct -igor On Wed, Mar 28, 2012 at 12:41 PM, Jeffrey Schneller <jeffrey.schnel...@envisa.com> wrote: > Here it is: > > > public class Admin extends WebPage { > > private Component workingPanel; > > public Admin() { > super(); > init(); > } > > @Override > public void renderHead(IHeaderResponse response) { > response.renderCSSReference("css/admin.css"); > super.renderHead(response); > } > > public void init() { > workingPanel = new MyEmptyPanel("workingPanel") { > @Override > public void onEvent(IEvent<?> event) { > if (event.getPayload() instanceof > MyPanelEvent) { > MyPanelEvent e = (MyPanelEvent) > event.getPayload(); > AjaxRequestTarget target = > e.getTarget(); > > Component replacement; > switch (e.getType()) { > case MyPanelEvent.PANEL1: > replacement = new > MyPanel1(this.getId()); > break; > case MyPanelEvent.PANEL2: > replacement = new > MyPanel2(this.getId()); > break; > case MyPanelEvent.PANEL3: > replacement = new > MyPanel3(this.getId()); > break; > default: > replacement = > Admin.this.workingPanel; > break; > } > > > Admin.this.workingPanel.replaceWith(replacement); // IS THIS RIGHT? > Admin.this.workingPanel = replacement; > // IS THIS RIGHT? > this.setOutputMarkupId(true); > target.add(this); > > target.appendJavaScript("alert('Panel changed to: " + e.getType() + > "');"); // place-holder for future javascript to be called > } > super.onEvent(event); > } > }; > workingPanel.setOutputMarkupId(true); > add(workingPanel); > > AjaxLink p1Link = new AjaxLink("p1Link") { > @Override > public void onClick(AjaxRequestTarget target) { > send(getPage(), Broadcast.BREADTH, new > MyPanelEvent(target, MyPanelEvent.PANEL1)); > } > }; > p1Link.setOutputMarkupId(true); > p1Link.setMarkupId("p1Link"); > add(p1Link); > > AjaxLink p2Link = new AjaxLink("p2Link") { > @Override > public void onClick(AjaxRequestTarget target) { > send(getPage(), Broadcast.BREADTH, new > MyPanelEvent(target, MyPanelEvent.PANEL2)); > } > }; > p2Link.setOutputMarkupId(true); > p2Link.setMarkupId("p2Link"); > add(p2Link); > > AjaxLink p3Link = new AjaxLink("p3Link") { > @Override > public void onClick(AjaxRequestTarget target) { > send(getPage(), Broadcast.BREADTH, new > MyPanelEvent(target, MyPanelEvent.PANEL3)); > } > }; > p3Link.setOutputMarkupId(true); > p3Link.setMarkupId("p3Link"); > add(p3Link); > } > } > > -----Original Message----- > From: Igor Vaynberg [mailto:igor.vaynb...@gmail.com] > Sent: Wednesday, March 28, 2012 3:29 PM > To: users@wicket.apache.org > Subject: Re: Event handling and swapping panels > > paste your entire panel/page class... > > -igor > > On Wed, Mar 28, 2012 at 12:15 PM, Jeffrey Schneller > <jeffrey.schnel...@envisa.com> wrote: >> Thanks.
