DataView - AjaxFallBackLink works only when outside DataView Link is once called
Hi,
I have one link within the DataView and one directly attached to the
Panel. The link within the DataView is added to the item within the
populateItem() method. This links gives me error when called *when*
the page is created:
WicketMessage: org.apache.wicket.WicketRuntimeException: component
events:dc:events:1:f:show_lk not found on page mypage[id = 2],
listener interface = [RequestListenerInterface name=IBehaviorListener,
method=public abstract void
org.apache.wicket.behavior.IBehaviorListener.onRequest()]
But, when I click another AjaxFallbackLink which is outside the
DataView then the link within the DataView starts working. I should be
calling something good in the link which is directly on the Panel.
Code of the AjaxFallbackLink#onClick outside the DataView is:
AjaxFallbackLink sort2_lk = new AjaxFallbackLink(sort2_lk) {
public void onClick(AjaxRequestTarget target) {
dataContainer.remove(events);
DataView dataView = createEventsDataView(list);
dataContainer.add(dataView);
target.addComponent(dataContainer);
}
};
dataContainer.add(sort2_lk);
Dataview is added to the panel using:
final WebMarkupContainer dataContainer = new
WebMarkupContainer(dc);
dataContainer.setOutputMarkupId(true);
dataContainer.setOutputMarkupPlaceholderTag(true);
DataView dataView = createEventsDataView(basicCommentWebs);
dataContainer.add(dataView);
dataContainer.add(setNavigator(dataContainer, dataView));
add(dataContainer);
private DataView createEventsDataView(ListBasicCommentWeb list) {
final DataView dv = new DataView(events, new ListDataProvider(
list)) {
@Override
protected void populateItem(final Item item) {
...
Form f = new Form(f);
AjaxFallbackLink hide_lk = new
AjaxFallbackLink(show_lk) {
@Override
public void onClick(AjaxRequestTarget
target) {
System.out.println(\n Hide on
onClick);
//mcp.setVisible(false);
//target.addComponent(mcp);
}
};
f.add(show_lk);
}
I have added setOutputMarkupId(true) and
setOutputMarkupPlaceholderTag(true) on the Form and links also, but
results are still the same.
What i am doing special in the case of AjaxFallBackLink which is
attached directly to the Panel?
thanks
devush

IndexedParamUrlCodingStrategy pageparameter null
Hi, (Wicket 1.4.8 in the development mode) I am mounting my page like this: mount(new IndexedParamUrlCodingStrategy(/i/about, AboutPage.class)); I am able to call /i/about without any problems, but when I call /i/about/somevalue I expect to have PageParameters not null. I am calling this in my web page, but p is always null. PageParameters p = getPageParameters(); Is not that the PageParameters should have 0=somevalue, which i should be getting by p.getString(0); thanks, devush - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Hi, Thanks, yes I have ignored that. It is now working. You have saved my weekend! thanks devush PS: Sorry, by mistake I directly replied to Martin.

Servlet Mapping Expectations
Hi, I have following settings in web.xml servlet-mapping servlet-namemyserv/servlet-name url-pattern/app/*/url-pattern /servlet-mapping I expect that all requests such as: /app /app/abc /app/xyz should come to the servlet. But only /app currently works. Moreover, I want to access the getRequestURL part from the servlet API also, so that i can use the information in the application logic. I am able to do this in the normal servlet and then forward the request to the wicket but in that case the URL at the client remains the same and causes problems later in the application. thanks devush - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Servlet Mapping Expectations
Hi, I am able to get the request related information from both Request and WebRequest. Thanks for that. This i am able to do in the WebPage. My WebApplication getHomePage is called when ever I call /app or /app/, so I have to intercept the request before that. I am trying with mount(String, Package), but that lead to the specific URL only. This is in the init() method of WebApplication. My basic requirement is to serve pages like /app/user1 /app/user2 /app/user2/profile etc. Do i have to create new* methods as described at https://cwiki.apache.org/WICKET/request-processing-overview.html Do I have to implement IRequestCodingStrategy and attach it to Request Cycle? thanks devush On 05/03/2011, Martin Grigorov mgrigo...@apache.org wrote: Hi, On Sat, Mar 5, 2011 at 4:03 PM, devush devushan...@gmail.com wrote: Hi, I have following settings in web.xml servlet-mapping servlet-namemyserv/servlet-name url-pattern/app/*/url-pattern /servlet-mapping I expect that all requests such as: /app /app/abc /app/xyz should come to the servlet. But only /app currently works. They actually come but since you don't have mounts at /abc or /xyz Wicket decides there is nothing to do for them. /app matches on the App's home page.

I am able to do this in the normal servlet and then forward the request to the wicket but in that case the URL at the client remains the same and causes problems later in the application. See if Wicket's Request#getPath() (Wicket 1.4.x) or #getUrl() (Wicket 1.5.x) returns what you need. Otherwise you can always use the underlying HttpServletRequest: - 1.4.x - WebRequest#getHttpServletRequest() - 1.5.x - (HttpServletRequest) Request#getContainerRequest() thanks devush - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Unexpected RuntimeException with PagingNavigator
Dear All,
I am trying to get a Pagingnavigator using DataView.
I get following exception(Jetty 6.1.4 DEVELOPMENT mode, Wicket 1.4.5 ):

Unexpected RuntimeException:
WicketMessage: The component(s) below failed to render. A common problem is

Current Class extends the WebPage. My code looks like:
IDataProviderContact itemDataProvider = new IDataProviderContact() {
public Iterator iterator(int first, int count) {
Object[] objs = list.toArray();
List outList = new ArrayList();
for (int i = first; i count; i++) { // i know this is not clean
Contact c = (Contact) objs[i];
outList.add(c);
}
return outList.iterator();
}
public IModelContact model(final Contact object) {
return new LoadableDetachableModel() {
@Override
protected Contact load() {
return (Contact) object;
}
};
}
public int size() {
return list.size();
}
public void detach() {}
};
DataView dataView = new DataView(mywork, itemDataProvider, 5) {
protected void populateItem(Item item) {
Contact contact = (Contact) item.getModelObject();
item.add(new Label(id, contact.getId()));
}
};
dataView.setItemsPerPage(5);
add(dataView);
add(new PagingNavigation(nav, dataView));
It works fine if I take the PagingNavigation out of code.
My HTML Code is:
table cellspacing=0 class=dataview
tbody
tr wicket:id=mywork
tdspan wicket:id=idTest ID/span/td
/tr
/tbody
/table
span wicket:id=navnavigation controls here/span
Apart from this, i also tried with
new DataView(mywork, new ListDataProvider(list))
any ideas where I am wrong.
regards,
devush
