Re: Article: Introducing Apache Wicket
Question on detachable models: You use detachable models in the contact edit page. It seems like this would cause your changes to be lost if the edit process takes more than one request to complete. If you use the no-arg constructor, the loadableDetachableModel creates a new contact at the beginning of every request. If you enter a name that's too long, a validation message is displayed. Then the detach() is called on the model, and a new Contact is loaded on the next request, erasing your temporary changes. I may well be misunderstanding something, I'm fairly new to this stuff. It seems that for edit pages you want a non-detachable model, which gets serialized to the session. Thanks for taking the time to write this article, and thanks in advance for any clarification on this topic. -- Sam Barnum 360 Works http://www.360works.com 415.865.0952 On Jan 28, 2008, at 11:02 AM, Nick Heudecker wrote: It's finally up: http://www.theserverside.com/news/thread.tss?thread_id=48234 Thanks to the various reviewers that helped improve both the content and quality of the article, including Martijn, Eelco, Igor, Gerolf and Talios. -- Nick Heudecker Professional Wicket Training Consulting http://www.systemmobile.com Eventful - Intelligent Event Management http://www.eventfulhq.com
Re: Article: Introducing Apache Wicket
if there is a form error then the changes are never applied to the pojo in the first place. wicket's form workflow is atomic - the model object is ever updated when all required,type conversion,validation was successful on all form components in the form. if something failed wicket will keep the input and display it again when the form is rerendered. makes sense? -igor On Jan 31, 2008 6:42 PM, Sam Barnum [EMAIL PROTECTED] wrote: Question on detachable models: You use detachable models in the contact edit page.

Re: Article: Introducing Apache Wicket
i came across a problem with this article's code. i will try to explain the use case. after you insert a few contacts, open another browser, you can see same screen on both browsers. after deleting a contact from a browser you are still seeing deleted contact. after that, click the deleted contact's edit link. you will see different contact that you can edit. it is because detachable model can load different subset of records and component only gets the index of a record from http request, not id of a record. how can i solve this problem? -- View this message in context: http://www.nabble.com/Article%3A-Introducing-Apache-Wicket-tp15142773p15183311.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: Article: Introducing Apache Wicket
the loadable detachable model should have the pk of the contact itself thats behind the edit link On Jan 30, 2008 3:59 PM, dozgurc [EMAIL PROTECTED] wrote: i came across a problem with this article's code. i will try to explain the use case. after you insert a few contacts, open another browser, you can see same screen on both browsers. after deleting a contact from a browser you are still seeing deleted contact. after that, click the deleted contact's edit link. you will see different contact that you can edit. it is because detachable model can load different subset of records and component only gets the index of a record from http request, not id of a record. how can i solve this problem? -- View this message in context: http://www.nabble.com/Article%3A-Introducing-Apache-Wicket-tp15142773p15183311.html Sent from the Wicket - User mailing list archive at Nabble.comhttp://nabble.com/ . - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Article: Introducing Apache Wicket
I think the link in the ListView uses the index of the object in the list, not the primary key. That's likely the problem.

Re: Article: Introducing Apache Wicket
Karthik, Thanks for the kind words. Just to put the record straight, it was one of our new developers at jWeekend, Dmitry Kandalov, that came back with the most useful parts of the feedback we gave when we reviewed your article and it's always a pleasure for us to try to help with anything that will increase awareness of how good Wicket is.

Thanks. I didn't want to bog the reader down with too many concepts at once. I'm hoping to make this a series on TSS to allow for more in-depth coverage.
