PageableListView item removal
Hi all,
I'm looking at a strange behavior of my PageableListView.
I have a PageableListView with an AjaxPagingNavigator within a
WebMarkupContainer. Recently I added an AjaxLink to the list view that
removes an element from the underlying list. The view refreshes, but takes
off the first(!) element of the list view instead of the element that was
really deleted. If I refresh the whole page, the view displays correctly.

Also, the ajax timer on the markup container stops after I hit the
removeLink.

I wasn't using the "setReuseItems" property at all, but tried to set it to
false: no change. Here's the code:
serviceContainer = new WebMarkupContainer("serviceData");
serviceContainer.setOutputMarkupId(true);
serviceContainer.add(new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(15)){
protected void onPostProcessTarget(AjaxRequestTarget target){
try {
services =
administrationService.updateServices(uniqueId, midm, userMidm);
logger.debug("{}:{}: Services refreshed for user " +
username, uniqueId, midm);
updateCounter ++;
//stop update after 15 minutes
if (updateCounter > 60){
logger.debug("{}:{}: Stopped service self updating
behavior", uniqueId, midm);
stop(target);
}
} catch (Exception e) {
logger.debug("{}:{}: Unable to refresh the service
view for user " + username,
uniqueId, midm);
warn("The system is unable to refresh the service
view. Please reload the user.");
}
target.add(feedback);
}
});
PageableListView<Service> serviceList = new
PageableListView<Service>("serviceList",
new
PropertyModel<List<Service>>(ServicesTabPanel.this, "services"),
ELEMENTS_PER_PAGE) {
@Override
protected void populateItem(ListItem<Service> item) {
final Service service = item.getModelObject();
final String serviceType = service.getServiceType();
item.add(new Label("serviceType", new
PropertyModel(item.getModel(), "serviceType")));
item.add(new Label("login", new
PropertyModel(item.getModel(), "serviceLogin")));
item.add(new Label("context", new
PropertyModel(item.getModel(), "serviceContext")));
item.add(new Label("status", new
PropertyModel(item.getModel(), "accountStatusWebString")));
item.add(new Label("syncDate", new
PropertyModel(item.getModel(), "timestamp")));
item.add(new Label("expireDate", new
PropertyModel(item.getModel(), "serviceExpireDate")));
if (service.isIntegrable())
item.add(new Label("integratable", "true"));
else
item.add(new Label("integratable", "false"));
if (service.isIntegrated())
item.add(new Label("integrated", "true"));
else
item.add(new Label("integrated", "false"));
item.add(new AjaxLink("syncButton"){
public void onClick(AjaxRequestTarget target) {
try {
logger.info("{}:{}: Synchonizing " +
serviceType + " services for " + userMidm, uniqueId, midm);
administrationService.syncMidasUserService(uniqueId, midm, userMidm,
serviceType);
success("Synchronized Service

} catch (Exception e) {
logger.error(uniqueId + ": Caught an
exception during admin sync service " + serviceType, e);
error("An error occurred while trying to
synchronize service " + serviceType);
}
target.add(feedback, serviceContainer);
}
});
addRemoveServiceLink(item, service);
}
private void addRemoveServiceLink(ListItem item, final
Service service){
AjaxLink removeServiceLink = new
AjaxLink("removeServiceLink"){
public void onClick(AjaxRequestTarget target) {
int userMidm = service.getMidm();
try {
administrationService.removeServiceFromUser(uniqueId, midm, userMidm,
service);
success("Successfully removed service " +
service.getServiceType() +
"(login " +
service.getServiceLogin() +") from current user.");
services.remove(service);
}
catch (UnavailableDataSourceException e) {
error("A database error occurred while
trying to remove the service " + service);
}
target.add(feedback, serviceContainer);
}
};
if (!isAccountChangePermitted)
removeServiceLink.setVisible(false);
item.add(removeServiceLink);
}
};
serviceContainer.add(serviceList);
AjaxPagingNavigator serviceNavigator = new
AjaxPagingNavigator("serviceNavigator", serviceList);
if (services.size() > ELEMENTS_PER_PAGE)
serviceNavigator.setVisible(true);
else

Hi,
you're probably using #setReuseItems(true) ?
Show us your #populateItem() please.
