Hello,
I tried your approach and could find one mistake in my code.
After the stepwise adding of the components to my results page,
I found an error in two of my classes that are used on that page.
These two classes did not implement the Serializable interface.
I added the interface to these two classes and the PageExpired
error was gone.
But there is still another error. My PageableListView does not
display the results when I click on one of the links in the
AjaxPagingNavigator. The first page is displayed but the other
pages in the list are nearly empty.
They are not completely empty. I have 3 elements in an item of
the PageableListView populateItem Method that must be filled
in the html page.
The elements are title, description and time.
My code looks as follows:
/***************
* Code
*/
private void displayResults(Vector<LoadableListingEntryModel> results, int
entriesPerPage) {
WebMarkupContainer datacontainer = new
WebMarkupContainer("listviewContainer");
datacontainer.setOutputMarkupId(true);
add(datacontainer);
PageableListView listview = new PageableListView("listview", results,
entriesPerPage) {
StringBuilder sb;
@Override
protected void populateItem(ListItem item) {
if (item != null) {
LoadableListingEntryModel model =
(LoadableListingEntryModel)item.getModelObject();
DefaultSearchResult s =
model.getObject().getResult();
String description = s.getDescription();
String title = s.getTitle();
item.add(new ExternalLink("title", title));
item.add(new Label("description", description));
item.add(new Label("time",
s.getTime()).setEscapeModelStrings(false));
}
}
};
listview.setReuseItems(true);
datacontainer.add(listview);
AjaxPagingNavigator apn = new AjaxPagingNavigator("navigator",
listview){
@Override
protected void onAjaxEvent(AjaxRequestTarget target) {
super.onAjaxEvent(target);
target.appendJavaScript("scrollTo(0,0)");
}
};
datacontainer.add(apn);
datacontainer.setVersioned(false);
}
/***************
* Code
*/
The LoadableListingEntryModel was one of the two classes
that got the Serializable interface.
When I click on one of the links of the AjaxPagingNavigator,
the title and the description fields are emtpy. The time
field is filled.
I checked the items and have e.g. 60 items with title,
description and time content. But only the time content
is displayed, when I click on one of the
AjaxPagingNavigator links.
This error only occurs, if the Google Adsense Code is
in the site. Could it be possible, that the Ajax call of
the PageableListView has a problem?
Thanks,
Andre
