The whole point of a constructor that takes PageParameters is to use it with
a bookmarkable URL, which you've avoided by creating an instance of a page
that must be redirected to. Your code should say:
setResponsePage(getApplication().getHomePage(), parameters);

Re: Links in DataTable
Thanks for your answers.
I set the multi window support settings to true, and that did not make a
difference. Interestingly, the javadoc shows that multiwindow support is
true by default. I also tried setting it to false, with no luck.
However, setting the response to a new page on click seems to conserve the
original page usability. My guess is because a new page is then created, so
the current page is still valid, and the elements on it are still valid.
I am trying a bookmarkable page link instead of the onclick event, which
seems to work, except that the AJAX actions (example paging) in the original
page return an expired page message.
Still investigating, if anyone has more information it will be greatly
appreciated.
I am working in migrating an existing large JSP/Servlet/Struts app to
Wicket, and the pattern, that is open new detail windows or tabs from a AJAX
list, is heavily used by our customers. So I have to find a way to solve
this issue without limiting existing functionality. Sadly, I am pretty new
to wicket, so I dont know the internals of why a page should loses its
containers or expires in this cases.

Problem was, that you opened new windows in same page map.

Re: Links in DataTable
Since AjaxLink is AJAX and not a proper link, then it does behave as a
normal link, i.e. middle click (open link in new tab or new window) does not
trigger the AJAX click even, which means you cannot chose to open the link
in a new page.
back to square one, except that know I know is a problem with
AjaxFallbackDefaultDataTable, not with DataTable.

Re: Links in DataTable
Jeremy, the code is below.
I did notice something while researching/testing more.
The LinkPanel solution DOES work for a DataTable. The problem starts when
changed to a AjaxFallbackDefaultDataTable.
I did testing based in the datatable example in the wicket examples.
Maybe using an AjaxLink instead of a normal link in the table is the right
answer.
Code is mostly taken from the page linked in the original email
public abstract class LinkPanel extends Panel {
private static final long serialVersionUID = 2062173455224348354L;
public LinkPanel(final Item item, final String componentId,
final IModel model, final String property) {
super(componentId, model);
AjaxLink link = new AjaxLink("linkCell") {
private static final long serialVersionUID =
2574434147588617330L;
@Override
public void onClick(AjaxRequestTarget target) {
LinkPanel.this.onClick();
}
};
add(link);
link.add(new Label("label", new PropertyModel(model,property)));
}
protected abstract void onClick();
}
- Usage ---
public class LinkPanelPage extends WebPage {
public LinkPanelPage() {
Form form = new Form("form");
final LinkPanelListProvider provider = new LinkPanelListProvider();
List columnList = new ArrayList(3);
//columnList.add(new PropertyColumn(new
Model("eMailAddress"),"eMailAddress"));
columnList.add(new AbstractColumn(new Model("eMailAddress"),
"eMailAddress") {
private static final long serialVersionUID =
-1822504503325964706L;
@Override
@SuppressWarnings("unchecked")
public void populateItem(Item cellItem, String componentId,
final IModel rowModel) {
cellItem.add(new LinkPanel(cellItem, componentId, rowModel,
getSortProperty()) {
private static final long serialVersionUID =
-4615958634366803506L;
@Override
protected void onClick() {
System.out.println("clicked on link");
}
});
}
});
columnList.add(new PropertyColumn(new
Model("firstName"),"firstName"));
columnList.add(new PropertyColumn(new
Model("lastName"),"lastName"));
AjaxFallbackDefaultDataTable table = new
AjaxFallbackDefaultDataTable("link-panel-table", columnList, provider, 3);
form.add(table);
add(form);
}

Links in DataTable
I am trying to create a table based on DataTable, in which one of the columns has links on it. I tried to use the strategy described here (LinkPanel): https://cwiki.apache.org/WICKET/adding-links-in-a-defaultdatatable.html But this has a problem: clicking in the links in succession soon causes "component not found exceptions", or opening the link in a new window or tab renders the current page unusable, with the same exception. rg.apache.wicket.WicketRuntimeException: component . not found on page ... at org.apache.wicket.request.AbstractRequestCycleProcessor.resolveListenerInterfaceTarget(AbstractRequestCycleProcessor.java:426) at org.apache.wicket.request.AbstractRequestCycleProcessor.resolveRenderedPage(AbstractRequestCycleProcessor.java:471) at org.apache.wicket.protocol.http.WebRequestCycleProcessor.resolve(WebRequestCycleProcessor.java:144) at org.apache.wicket.RequestCycle.step(RequestCycle.java:1310) ... I believe this is due to the fact that a new LinkPanel is created when rendering each column cell, and that when the click happens, the current LinkPanels are replaced by new ones, and so the original page is not usable anymore, because it is referring to the original LinkPanels. Our users make heavy use of opening links in a list in new pages or tabs, so this is a big deal for us :( Is there any solution for this problem? The only one I can think of is to use AjaxLink instead, but I am not sure whether that is correct, or if it could cause even more problems. Any help? -Nelson
Reorder links in DataTable
Hi, is there a way to implement reordering of rows in DatTable? I'd like to add a column with moveUp,moveDown,remove having the same behaviour as corresponging links of the ListView component. I suppose DataTable should be set to model reusing with setItemReuseStrategy(ReuseIfModelsEqualStrategy.getInstance()) and DataProvider should be a simple wrapper around List object but could not find a more or less generic way to implement ListView reordering behavior. -- View this message in context: http://www.nabble.com/Reorder-links-in-DataTable-tp19062831p19062831.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
