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));
}
});
}
});
