In my case, I was adding something to 'this' instead of the parent / outer
item:
I think the line
*add(new ListView("reportItems", reportItems) {*
is implicitly
*this.add(new ListView("reportItems", reportItems) {*
and likely not what you want ... try changing it to
*listItem*.add(new ListView("reportItems", reportItems) {
or in context:
add(new ListView("reportList", reportVector) {
public void populateItem(final ListItem listItem) {
Vector<ReportItem> reportItems = ((ReportDAO)
listItem
.getModelObject()).getReportItems();
* listItem.add(new ListView("reportItems",
reportItems) {*
If that doesn't work for you - post the stack trace and try to match up the
line numbers to the source you've posted and someone here might spot the
problem.
