Can you please share the solution? I am doing something similar and I get java.lang.IllegalArgumentException: A child with id 'reoirtItems' already exists
/*java*/ add(new ListView("reportList", reportVector) { public void populateItem(final ListItem listItem) { Vector<ReportItem> reportItems = ((ReportDAO) listItem .getModelObject()).getReportItems(); add(new ListView("reportItems", reportItems) { protected void populateItem(final ListItem reportItem) { ReportItem item = (ReportItem) reportItem .getModelObject(); int copyId = item.getCopyID(); String image = item.getItemImage(); String itemClass = item.getItemClass(); String itemSubClass = item.getItemSubClass(); String itemLocation = item.getItemLocation(); String actionDate = item.getActionDate(); String status = item.getState(); String userID = item.getUserID(); reportItem.add(new Label("image", (image == null) ? "Unavailable" : image)); reportItem .add(new Label( "itemClass", (itemClass.equals("NA") || itemClass == null) ? "Unavailable" : itemClass)); reportItem.add(new Label("itemSubClass", (itemSubClass == null) ? "Unavailable" : itemSubClass)); reportItem.add(new Label("itemLocation", (itemLocation == null) ? "Unavailable" : itemLocation)); reportItem .add(new Label("actionDate", actionDate == null ? "Unavailable" : actionDate)); reportItem.add(new Label("status", status == null ? "Unavailable" : status)); reportItem.add(new Label("user", userID == null ? "Unavailable" : userID)); } }); } }); /*HTML*/ <table wicket:id="reportList"> <table wicket:id="reportItems"> <tr> --------------------------------------------- </tr> <td wicket:id="image">[image path]</td> <td> <table> <tr> <td class="label">Title:</td> <td wicket:id="title">[Item's Title]</td> </tr> <tr> <td class="label">Class:</td> <td wicket:id="itemClass">[class]</td> </tr> <tr> <td class="label">Sub-Class:</td> <td wicket:id="itemSubClass">[subclass]</td> </tr> <tr> <td class="label">Location:</td> <td wicket:id="itemLocation">[location]</td> </tr> <tr> <td class="label">Date:</td> <td wicket:id="actionDate">[Action Date]</td> </tr> <tr> <td class="label">Status:</td> <td wicket:id="itemStatus">[item state]</td> </tr> <tr> <td class="label">User ID:</td> <td wicket:id="itemStatus">[user id]</td> </tr> </table> </td> </table> </table> Sorry for posting my problem in your thread but i am a newbie here and i can't get to subscribe in the mailing list so I can't post any threads..
