Validating a Number using a Validator
Hi All, Basic question but have not got an answer to it. I want to validate a field to accept only numbers and provide a validation message. Is there a NumericValidator I checked NumberValidator but don't see how I can use it..it says its deprecated. TextFieldLong yearOfExpiry = new TextFieldLong(yearExpired); I guess the validator should check if it is of the right type(data type) ..i.e Numeric.. Or should I build a CustomValidator? If I have to would there be an example of how this can be built? Look at the Wicket Code base? Thanks guys Niv
Re: Validating a Number using a Validator
See org.apache.wicket.validation.validator.NumberValidator.MinimumValidator for example. In your custom validator's onValidate() you need to check that validatable.getValue() is an instance of Number.

Re: Validating a Number using a Validator
Thanks Martin, So I do have to build a CustomValidator that is established. I would have thought this was a basic one that would be off the shelf.No worries thank you for the time, will look at the NumberValidator.MinimumValidator implementation.

How to show pdf ByteArrayResouce in browser
I have class which generates pdf report. The report is generated as stream as I donot want to save the file in server. I need to show the pdf in the browser. But the link provided to this dynamically generated pdf opens a new window and asks for saving the file. How to open the pdf in new window? My piece of code: IResourceStream stream1 = new ByteArrayResource(application/pdf, stream.toByteArray()).getResourceStream(); getRequestCycle().setRequestTarget(new ResourceStreamRequestTarget(stream1).setFileName(eFile.pdf)); The stream here is the stream to which the pdf is written. I also tried the following code. But this gives null pointer exception getRequestCycle().setRequestTarget(new RedirectRequestTarget(urlFor(new ResourceStreamRequestTarget(stream1).setFileName(eFile.pdf)).toString())); Any help will be great. Thanks in advance. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-show-pdf-ByteArrayResouce-in-browser-tp3320759p3320759.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: How to show pdf ByteArrayResouce in browser
Hi; The browser must have the capability to render PDF, mostly via a plugin. I noticed google chrome browser renders pdf without any plugin installed. So i suggest you test with chrome first. There is an adobe plugin, that enables internet explorer to be able to render pdf once the plugin has been installed. Lastly, there is a project here -http://www.icepdf.org/ (i have never used it though) that can help in this area. Kind regards. Josh.
Re: How to show pdf ByteArrayResouce in browser
Thanks for the reply... I was able to render the pdf in browser with the
following piece of code:
ResourceStreamRequestTarget target = new ResourceStreamRequestTarget(null){
@Override
public void detach(RequestCycle requestCycle) {
// TODO Auto-generated method stub
}
@Override
public void respond(RequestCycle requestCycle) {
try{
OutputStream out =
requestCycle.getResponse().getOutputStream();
out.write(stream.toByteArray());
out.flush();
stream.close();
}
catch(Exception e){
e.printStackTrace();
}
}
};
getRequestCycle().setRequestTarget(target.setFileName(eFile.pdf));
But now the problem is that the file name I set in the last line doesnot
work. It renders as
ClassName.pdf
Any suggestions??? Thanks

Session optimization
Hi! Is there a way to swap sessions onto disk with jetty if they are idle for n.n. minutes? It is under investigation, but we suspect that we have many idle users logged in with large session size. So, while they are doing nothing, their session could be pushed onto disk. Is there a setting or utility or way to achieve this? We are using wicket+jetty. Simply shortening session destroy timeout is not an option. ** Martin - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Different styles in different windows on same application
Hi. We have a use case where we have one Wicket application that has multiple styles (passed in through a page-parameter).

Tab1 http://foo.bar/app/style/theme1 Tab2 http://foo.bar/app/style/theme1 As soon as you go back to tab1 and do something, the style changes. Is there a way to do this without putting the style on the session, but still be able to use the style and variation logic in Wicket?

Re: Wicket pages created by guice
OK, I managed to fix the problem. And here`s how: I used to have Form class injected in page, then Dao class injected in form, then hibernate session injected in dao class and that session was the one causing WicketNotSerializableException. But, when I create the form with new, it all goes away. While this will work, I still think it would be more... well, neat to have components injected on page. Some things you may look at IComponentInitalizationListener -- http://wicket.apache.org/apidocs/1.4/org/apache/wicket/application/IComponentInitializationListener.html IComponentInstantiationListener -- http://wicket.apache.org/apidocs/1.4/org/apache/wicket/application/IComponentInstantiationListener.html If your really wanting to use Guice/Spring have you considered using a panel/component and implementing your own provider/factory for the component?

Re: CheckBoxMultipleChoice.getInput() = NULL after switch to AjaxSubmit
Hi Kikiya, thanks a lot for the reply. Can you provide details on what you did? For everyone else reading this. Maybe the original post wasn't worded very well, but here's the issue: When I'm doing Form onSubmit(), CheckBoxMultipleChoice.getInput() returns correct results. However, in any Ajax code, CheckBoxMultipleChoice.getInput() returns NULL. This is only a problem with the CheckBoxMultipleChoice, not with any other fields. I talked with co-workers and we think it's because the top-level CheckBoxMultipleChoice isn't propagating the Input changes to the lower-level checkboxes. But on the Form onSubmit(), everything gets mapped correctly, and the whole checkbox group gives the right inputs on getInput().

Default session timezone
Hi, I am using Wicket 1.5 RC1. I want to set a default timezone for client sessions so I added the following line at the end of my CustomSession constructor: getClientInfo().getProperties().setTimeZone(TimeZone.getTimeZone(GMT)); Doing this coupled with getGatherExtendedBrowserInfo() == true however yields a null exception. Some analysis: In WebSession#getClientInfo(), there is no clientInfo yet and getGatherExtendedBrowserInfo() is true so a redirect is attempted. The line IRequestHandler activeRequestHandler = requestCycle.getActiveRequestHandler(); produces activeRequestHandler == null. Since there is no request handler, the following line String url = requestCycle.urlFor(activeRequestHandler).toString(); gives a null exception as urlFor returns null. If getGatherExtendedBrowserInfo() == false, the default timezone set in the Session constructor works fine. Is this the correct way to set a default time zone?
