Re: What is your experience on the time of development ?
This is a very interesting and surprising post in this forum. Do you have further explanation about your superior productivity using Grails? Is this due to the kind of applications you developp or to special tools that comes with this framework? Is the key stone groovy? Thanks for your enlighments! Curtis Cooley-2 wrote: Martin Sachs wrote: pI'm looking for a little comparison of the development-time for Applications in Wicket against other Technologies. /p p I think the development with Wicket is two times faster than Struts. But what are your experiences on JSF, Rails/Grails, SpringMVC/SpringWebFlow. /p Anyone you know the development-time from experience ? br (P.S.: The applications must use AJAX and many custom components or tags in JSP, not just a hello world sample) I built a small database driven application in about 4 days using Grails then my boss freaked about using a 4GL and made me rewrite it in Wicket. That took me about 3 weeks. Now, I started at 0 with both frameworks and used Wicket+Spring+Hibernate which I got Spring and Hibernate wiring for free with Grails. My Spring and Hibernate experience was 0, so grails really pulled through in that area. I also have experience with Ruby and Rails which helped with the Grails work, but I'd also built a few (4-5) Wicket pages for another app, so I think that about balances starting points. My really rough guess is that I'd be 50 to 75 percent more effective in Grails than Wicket now that I know what I learned during the three weeks of Wicket work. If I had my druthers, I'd build our app using Grails. I much prefer Groovy/Ruby to Java, and I've been writing Java since 1.1! Confidential/Privileged information may be contained in this email.

Re: Google Adsense.
I have no problem with this using wicket 1.4.rc1. And i never had problem using previous versions. Regards Alexandre ej595 wrote: Hi all, im not sure if anyone else has any experience of using google adsense within your wicket html, but i seem to be finding that it interferes with the rendering of the wicket pages. By that i mean, if i include the adsense code in the html, when wicket renders the page i get this intermittent 'unable to find component X' error. It seems to be something to do with the time it takes to retrieve the actual advert and the rendering of the page via wicket. It never happens on localhost, but once the war has been deployed to a web environment, the logs are littered with this error and the html stack traces. Im not entirely sure what to do other than to remove the ad. Once i remove the ad, the page is fine.

Accessing IFrame field from parent
I have a page and an IFrame is this page. I try to access in javascript, from the parent page, a field from the Iframe page. But firefox gives me a security exception. I understands that the URI of the IFrame and of the parent page are not the same, and that is why I get this exception. The paretn page is bookmarkable, and I could not have the IFrame page to be bookmarkable in order to have it having a sub URI with regard to the parent page. Is it possible to have control on the URI of an IFrame? Thank you for your attention.

Re: bookmarkable URL and sortable data table
I have encountered the same problem as you. I have solved it thsi way: The page that contains the table has parameters that reflects the state of the table. Then I created the class : public class BookmarkableOrderByBorder extends Border that is created by the overriden newSortableHader of mytable. This BookmarkableOrderByBorder includes a BookmarkablePageLink that include the sort state of my BookmarkableTable. I don't know if this is the ideal solution. Well, you can check the result here where several BookmarkableTables can be in a page: http://cubefactory.selfip.com/globalparanoia/clan.html/clan/PARANOIA/ http://cubefactory.selfip.com/globalparanoia/clan.html/clan/PARANOIA/ I hope you get the idea.

Good practice for temporary resource reference
I am doing an application with a lot of dynamical image creation. These images need to be cached client side, but their life time is bounded by the suer session's lifetime. So I create a lot of image resource references which url is used but the client. What I did not get in the APi is the way do forget those references, to unbind them to the application. Is there a canonical way to do so? Thanks for your reading.

Re: Good practice for temporary resource reference
Yes it could. I figured out to override newSessionStore in the application to have control over the undbind session call. I would have then remove the request references registred in the session during its life time at this time. I beleive that I have to remove my ResourceReference from the SharedResources of the application. I don't know if it it the correct way to do this. I found it by browsing the wicket source code (thanks it is open source). Anyone has tried to do something like that?
