Error with link in DataTable together with AjaxEventBehavior(onclick)
Hi, I have a DataTable. In this DataTable I want to be able to click on the rows in the table to make some stuff happen (by Ajax), for example highlighting the current row. To implement this I am overriding the newRow method in DataTable and adding an AjaxEventBehavior(onclick) to each row item. This works well, but when I add a Link to another page in one of the columns, I get a problem. When clicking the link I still trigger an onclick ajax event for clicking the row. But since the link takes me to another page, this ajax request will fail beacuse the page it belongs to is no longer available. Is there a way to prevent the onclick event from happening when I click on my link? Or is there a better way of doing this? Thanks!

Inmethod datagrid and Twitter bootstrap
Hi, I've been playing around a bit with the Twitter bootstrap css framework and think it looks really nice. Now, it would be very nice if it was possible to make the inmethod datagrid (which I use a lot) get the look and feel of the twitter bootstrap table. I'm thinking of making the inmethod datagrid look something like this: http://datatables.net/media/blog/bootstrap/ This means that I would also like to use the paging look and feel from twitter botostrap. I know there is a setTheme() method on the DataGrid component, but before I start digging too deep into that, it would be nice to hear from someone more involved with the inmethod DatGrid project if they think that what I'm trying to do is at all possible to achieve. Or maybe someone has already done it? Any thought on this would be very appreciated.

It will work even if I lose the reusability I had with keeping design in the border component. If I understand things correctly, it is not possible to have a wicket:child/ element which is not a direct child to the base panel, without providing some extra methods (or implement IComponentResolver). I'm not saying this is a bad thing, just trying to understand how things work now. Thank you for your time!

Re: Wrong path for resources on redirected login page
Hi! After som more hours of debugging I finally think I'm starting to understand what is happening here. The short version is that I think that this might indeed be an example of the forward problem in the case you pointed to above. Here is what I think is happening: * I point my browser to /App/StartPage * Tomcat *forwards* the request to /LoginPage, just as it's supposed to do according to my web.xml. Wicket is not involved in this forwarding. * Wicket renders the LoginPage * Here comes the confusing part... In WebPageRenderer, line 233, Wicket creates a new URL stored in a variable called targetUrl2. This URL will have an URL parameter, like LoginPage?123. This URL is then compared to the old URL (LoginPage) (Line 244). The URLs are not equal which results in Wicket (for some reason which is not immediately apparent to me) sending a redirect (Line 266) to the new URL stored in targetUrl2. * This will eventually result in Wicket calling the Tomcat sendRedirect method with argument LoginPage?123. To me it seems strange that Wicket first renders all of LoginPage, and then decides to redirect to the same page and render everything again. Seems like unnecessary work to me, but there may of course be much I dont see here. As far as I understand, the redirect to LoginPage?123 might have something to do with the page not being stateless, but it seems strange that all pages should have to be rendered twice (with a redirect) just because they are not stateless. As I said I guess this could be an example of this issue, though I'm not 100% sure: https://issues.apache.org/jira/browse/WICKET-4138 If that is the case, do you know when this issue will be fixed? Thank you! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wrong-path-for-resources-on-redirected-login-page-tp3920038p3953772.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wrong path for resources on redirected login page
I also thought that Tomcat should take care of the redirect configured in web.xml by itself, but that does not seem to be the case. To me it seems like Tomcat does create its own redirect response, but that Tomcat still calls its filter chain, which will invoke my WicketFilter which leads to wicket also constructing a redirect, which I would guess takes precedence over the one created by Tomcat. Using the debug tool in Google Chrome and FireBug in Firefox, I can affirm that the redirect really is a 302 redirect. Martin Grigorov-4 wrote: This looks wrong. It should be ../LoginPage instead. But I'm not sure that Wicket creates this redirect location. From the description in your first mail I think the web container (Tomcat) should care about the redirect. I.e. hitting an Url that requires authentication Tomcat will not deliver it to WicketFilter at all but will do the redirect to the 'form-login-page'. I'm not sure how exactly the web container does this though... If it is redirect 302 then all should be fine, but if it is RequestDispatcher.forward() then Wicket will be confused indeed.

Re: Wrong path for resources on redirected login page
I just realized something that should maybe have been obvious to me at once... I'm not at home and able to test this atm, but I'm quite sure that my WicketFilter is positioned before my security-constraint in my web.xml. I didn't think security-constraint was treated as a filter, so I didn't think the placement of that section mattered. But if the order matters, I guess that would explain why WicketFilter is invoked even when I expected Tomcat to make a redirect. If this is the cause of my problem I feel stupid... :) However, the same web.xml did work in wicket 1.4.18, probably due to lucky circumstances... -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wrong-path-for-resources-on-redirected-login-page-tp3920038p3932608.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wrong path for resources on redirected login page
Hi. I didn't get things to work with 1.5.2, seems to be the same behavior there. I've done some additional research and debugging... As far as I understand, my problem boils down to this: * Wicket creates a redirect from my StartPage (mounted as App/StartPage) to my LoginPage (mounted as LoginPage). * In the end of this redirect, wicket calls the sendRedirect(String location) method of the Response class of my web container, which in my case is org.apache.catalina.connector.Response (JBoss/Tomcat). As the location parameter, wicket sends LoginPage. * Looking into the source code of org.apache.catalina.connector.Response, I can see that Tomcat treats this as a relative URL. Since the last URL visited was App/StartPage, tomcat renders the redirect URL to be App/LoginPage. * My browser receives the redirect and asks for the page App/LoginPage. Although this URL is wrong, wicket somehow seems to work out that LoginPage is the page to access, but no resources are loaded bacause of wrong URLs. I've tried mounting my LoginPage like: mountPage(/LoginPage, LoginPage.class); But that attempt was futile, since it seems like wicket strips the / in the beginning of a mount URL. The question now is whether this is a wicket or a tomcat issue (or both, or none :) ). As far as I can see, if wicket called the org.apache.catalina.connector.Response with sendRedirect(/LoginPage), things would work out. But there may well be many things I dont understand here... Bottom line... * Is my scenario meant to work? * Are my conclusions correct? * If so, should I create a JIRA case on this issue?

Re: Wrong path for resources on redirected login page
Thank you for your quick replies! I have been trying to set up a quickstart with wicket version 1.5.2 to test things out, but it seems like its not totally trivial to set up security constraints in web.xml using jetty. I tried to add the following to my web.xml: security-constraint web-resource-collection web-resource-nameAll resources/web-resource-name descriptionProtects all resources/description url-pattern/App/*/url-pattern /web-resource-collection auth-constraint role-nameUSER/role-name /auth-constraint /security-constraint security-role role-nameUSER/role-name /security-role login-config auth-methodBASIC/auth-method realm-nameApp Realm/realm-name form-login-config form-login-page/LoginPage/form-login-page form-error-page/LoginErrorPage/form-error-page /form-login-config /login-config But that resulted in an error message from jetty: java.lang.IllegalStateException: No LoginService for org.eclipse.jetty.security.authentication.BasicAuthenticator@494b6bed in org.eclipse.jetty.security.ConstraintSecurityHandler@769aba32#STARTING Seems like you have to add something called LoginService to jetty to make security stuff work.

Wrong path for resources on redirected login page
Hi, I have the following setup: Two pages mounted like follows: mountPage(App/StartPage, StartPage.class); mountPage(LoginPage, LoginPage.class); In my web.xml, I have added a security constraint to the /App/ path and set up the form-login-page to be /LoginPage. This means that when I go to the address App/StartPage, tomcat redirects me to /LoginPage, which is working fine. However, none of my resources are loaded. The reason seems to be that wicket still believes that my base URL is /App/, when it should actually be /. The URL shown in the browser address field is /App/LoginPage?0. Resources on my LoginPage are loaded with PackageResourceReference, like: add(new Image(logo, new PackageResourceReference(LoginPage.class, images/logo.png))); Other resource, like css, are loaded like: response.renderCSSReference(new CssResourceReference(LoginPage.class, style.css)); This approach was working fine in 1.4.18. Right now I'm using 1.5.1. I know that both the resource handling and URL rendering have been changed in wicket 1.5, but I haven't been able to figure out what (if anything) I'm supposed to change to make this work again. Does anyone have any ideas? Or is there a better way to set up things? I've been looking at this case, it feels similar to my problem but if it was the same it should have been fixed in 1.5.1: https://issues.apache.org/jira/browse/WICKET-4030 I hope this is understandable.

Re: Wrong path for resources on redirected login page
Addition to my post above: I noticed that the browser URL seems to be the same in both 1.4.18 and 1.5.1: /App/LoginPage But, in 1.4.18 the resource links looked something like this: ../resources/se.app.LoginPage/images/logo.png while in 1.5.1 it looks lke this: wicket/resource/se.app.LoginPage/images/logo-ver-1319057388417.png So, no ../ in 1.5.1 which I guess is what's causing my problems. In 1.4.18 it seems that wicket automagically solved the resource path issue. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wrong-path-for-resources-on-redirected-login-page-tp3920038p3920126.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: component .... not found on page for a Link colun in the Datatable after self refresh using the AjaxSelfUpdatingTimerBehavior
Hi,
My conclusion is that this is not really a wicket error, since we're
clicking a link which no longer exists after the Ajax update.
My solution to this has been to catch these exceptions in my
WebRequestCycleProcessor, like this:
@Override
public IRequestTarget resolve(RequestCycle requestCycle,
RequestParameters requestParameters) {
try {
return super.resolve(requestCycle, requestParameters);
} catch (InvalidUrlException e) {
if
(requestCycle.getRequest().getURL().contains(ILinkListener)) {
return new
PageRequestTarget(requestCycle.getRequest().getPage());
}
throw e;
}
}
What happens is that if I get this exception and the request URL contains
ILinkListener, I just return the page which the user is already at. For
the user it will seem like nothing happens, which at least is better than
that they get an exception.
This is not a pretty solution, but the best I could think of. If someone
knows of a better or more general soultion to this problem I would be happy
to know.

Re: component .... not found on page for a Link colun in the Datatable after self refresh using the AjaxSelfUpdatingTimerBehavior
Hi,
Did you find a solution for this?
I'm using wicket 1.4.8 and get almost the same error. Like you I have a
customized column with a Link component in a datagrid. I have an ajax search
field which updates the data (and the links) in the data grid when changing
the search input. Sometimes if I click the link very quickly after I have
changed the search value,, I get the same exception as you:

at
org.apache.wicket.protocol.http.WebRequestCycleProcessor.resolve(WebRequestCycleProcessor.java:144)
But, if I wait one or two seconds before clicking, I never get this error.
It seems like this has to do with the re-rendering of the page after the
ajax request. At the moment the link is clicked, the link listener is not
present on the server side.
The question is if this should be considered a bug in Wicket or if this is
by design.
I'm thankful for any input on this.

So you're suggesting that the close() method of the IResourceStream
should
be removed?
Isn't there a point in having the close() method? In my case, by
overriding
the close() method, it would be possible to be notified when a download
is
complete. Don't know how else I would accomplish that (any
suggestions?).
Wouldn't it be a better idea to implement a close() method with default
close behaviour in the abstract classes implementing the IResourceStream
interface? That way, by extending one of these abstract resource stream
classes, you dont have to mind about the close() method if you dont want
to.

The implementation of the getResourceStream() method of my WebResource

ResourceStreamNotFoundException {
bais = getByteArrayInputStreamFromDB();
return bais;
}
public void close() throws IOException {
bais.close();
markByteArrayAsDownloadedInDB();
}
};
}
Why is it that the close() method is never called? Is there a
better/other
way to do it? Is it at all possible to get a callback when a user is
finished downloading the bytearray?
Thanks in advance!

Change row appearance in a DataGrid
Hi! I've just started learning Wicket and like it very much so far. I've found the very nice DataGrid component, for which I have a question: Is it possible to alter the appearance of a row in the grid in some custom way? What I want to do is that depending on my row data, I want all text in certain rows to be printed with bold text-weight. In other words, I want to add a class attribute to some of the rows, for which I can provide a style sheet. Is this possible in some way? Thanks in advance! /Daniel -- View this message in context: http://www.nabble.com/Change-row-appearance-in-a-DataGrid-tp20207345p20207345.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]
Re: Change row appearance in a DataGrid
Thanks for the very quick reply! I may be stupid but DataGrid doesn't seem to have a newRowItem() method to override. I did some googling and found that you can do just this for DataGridView, but I'm using DataGrid, which does not extend from AbstractGridView (which has the newRowItem method), but from AbstractGrid. Am I missing something obvious here? /Daniel jwcarman wrote: Override newRowItem() and decorate it however you want (using AttributeAppender behavior perhaps).
