Re: Presented Wicket to my Company...
Well here's our story, if it helps you. Traditionally we had a JSP+Struts+EJB2 model for all our projects. For our current project we decided to jump on the JEE5 bandwagon, and started out with JSF+EJB3 (SLSB)+ JPA, Now JSF and JSPs don't mix well, so we choose Facelets, and instead of struts we decided to use Seam, as that was the only available glue between the Web and EJB tier. So we had to learn JSF, Seam, Facelets, EJB3 and JPA. Now seam is no good without Stateful Session Beans so we had to change our SLSBs to Stateful Session Beans, and we had all sort of problems with Extended Persistence Context, not to mention, most developers hated Seam as it was very buggy in those days (late 2006, early 2007). We also had a remote EJB3 API layer, and JPA managed entities (especially the ones with lazy loading relationships) don't mix too well with remoting. And even after learning all these new technologies, our web pages, were still lacking all the fancy AJAX stuff. Now we had to learn Icefaces or ajax4jsf . Every body hated every aspect of this development model. Now we have a much saner development environment. Wicket + EJB3 (bcoz we still need remoting) + Spring + iBatis. If we didn't need that EJB remoting layer I would drop EJB3 like a hot potato. My advice, don't worry about the industry standard thing, if you have good developers , then go with Wicket. The first time I hooked up AjaxFallBackDefaultDataTable with my Spring DAO + iBatis, It nearly brought tears to my eyes. Using iBaits I am able to do sorting,filtering,paginating all in the Database, (as it should be done, instead of storing huge datasets in memory and doing it in code), and the DataTable Component gives me all the hooks to plug this in so smoothly. Can't think how I would have managed this with JSF and JPA. So use Wicket for Web and iBatis for ORM. :) robert.mcguinness wrote: ...to tell you the truth, it impressed the developers but I didn't get that feeling from the top brass. I am pretty sure we will move towards Seam/JSF/Facelets (we have a presentation on that tech next week given by another developer) since it is standard. Has anyone here worked with the Seam tech? All the examples I have seen (including Facelets) is nothing but tag soup with scriptlets in the page (albeit small). The configuration for a Seam project seems like a pain and was also told that the JSF/Seam/Faclets jsp pages can be previewed in a browser (something I thought was so clever about Wicket html pages...and I was under the impression that Wicket was the only tech that allowed true separation of concerns; allowing the web designer to work independenly of the programmer with no duplication of work between the two). Maybe I'm blind to Wicket and I'm overlooking Seam and the techs related to it? I've worked with Freemarker and Struts before and Wicket feels like natural web development. I thought I covered all the great concepts about Wicket: Ajax, Templating, Inheritance, Reusable Components, OO Concepts…etc… Bah…just venting. I’m going to have to win the votes of the developers. I’ll keep everyone posted. Thanks amigos! - rm3 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
modal window rendering not quite smooth
has any one noticed that the modal window when opens up , shows the contents of the parent page, before showing it's actual content. The time for which it shows parent page's content depends on how much time it takes to fetch it's content via ajax. Is it possible to show a busy indicator in the modal window, while it fetches the contents, rather than showing parent pages content ? thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Using ClientProperties Object for User selectable Timezone.
Currently ClientProperties object has a getTimeZone() method, that uses BrowserInfoPage's response, to calculate a client's Timezone. Would it be too much trouble to add a setTimeZone() method, so that the TimeZone property is user settable ? I can save a user's preferred timezone, in a user profile object and store that in a session. But the wicket-datetime java classes, depend on the ClientProperties.timeZone field, to properly convert dates to--fro between the server and client timezones. So the best place to store a user's preferred timezone seems to be the ClientProperties object . thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Editable DataTeble
One thing to keep in mind about AjaxEditableLabel in wicket 1.3 is that the cancel functionality doesn't work well in firefox. See this for details https://issues.apache.org/jira/browse/WICKET-520 in essence, once you are in edit mode in firefox, there is no way to cancel the edit, other than to navigate out of the page. thanks fero wrote: Thanks, I think I will use AjaxEditableLabel more often;) Fero Eelco Hillenius wrote: On 8/19/07, fero [EMAIL PROTECTED] wrote: I see, but I don't know how to do editable labels.

Redirected after BrowserInfoPage and mounted Pages.
Short description :- When using mounted pages, wicket redirects to wrong URL, after BrowserInfoPage, which is called by Session.get().getClientInfo(), when gatherExtendedBrowserInfo is true in RequestCycleSettings. Long description :- I need to determine the Client's time zone in my webapplication. So I have set getRequestCycleSettings().setGaterExtendedBroserInfo(true) in my application class. And in my BasePage.java's (which is the super class for all my pages) constructor I have set getSession().getClientInfo(), to trigger the redirect to BrowserInfoPage as per the javadocs. My webapp context is /scheduler/ and my wicket application is mapped to /app/ (i.e. /scheduler/app/ ). I have kept all my pages in one package and mounted that package to /pages, ie. the pages are accessed via http://host/scheduler/app/pages/XYZPage etc. When I submit the request to http://host/scheduler/app/ This is what happens (I have recorded the HTTP traffic via wireshark). GET http://host/scheduler/app/ Temporary Redirect to http://host/scheduler/app/pages/HomePage (this is my home page). GET http://host/scheduler/app/pages/HomePage Temporary Redirect to http://host/scheduler/app/pages/../;jsessionID=.. (this is the BrowserInfo Page). GET http://host/scheduler/app/;JSESSIONID=. (get the browser info page). POST to browser info page. Temporary redirect to http://host/scheduler/app/pages/../../app/pages/HomePage (redirect from browser info page, after it has populated ClientProperties). The problem is that last redirect is wrong. The path http://host/scheduler/app/pages/../../app/pages/HomePage translates to http://host/app/pages/HomePage i.e. I lose the webapp context path (/scheduler/) because of the path being 2 levels up. and I get a 404 after that. I suspect the culprit is the throw new RestartResponseAtInterceptPageException(new BrowserInfoPage(getRequest().getRelativePathPrefixToContextRoot() + getRequest().getURL())); In WebRequestCycle.java. The getRelativePathPrefixToContextRoot() is computed wrongly as /scheduler/app/../.. instead of /scheduler/app/.. because the context root is /scheduler/ and not / Any thoughts on how to fix this ? thanks bhaskar - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Editable DataTeble
well, there's the editable tree table, http://wicketstuff.org/wicket13/nested/?wicket:bookmarkablePage=%3Aorg.apache.wicket.examples.ajax.builtin.tree.EditableTreeTablePage Else, you can add AjaxEditInPlace Label component, to your cells. fero wrote: Hi, is it possible to make an editable DataTable? I want that user can change or add an information into the table and it will be transfered through PropertyModel to my object behind the row in the table. I am trying everything and googling for it, but still nothing. Thanks a lot Fero - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Previous Page ref. in PageParameters
Can a ref. to the previous page be passed via PageParameters. What I am trying to do is have a BookmarkablePage The PageParameters if contain a ref. to previous field, will display a go back link. I can pass the prev page as a ref. in the constructor, but then the page is not bookmarkable, I need to pass some sort of ref. to the current page, via PageParameters and look it up in the next page's constructor. some thing like PrevPage p = getPageMap.get(pageParams.getString(prevPage)) any thoughts. thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
DownloadLink for an external URL
I see that DownloadLink can be used to stream a File.
What I want to do is use DownLoadLink to redirect to an external URL
that should be streamed (i.e. File Save box should pop up).
I can't use ExternalLink as the external URL's location is not pre determined,
also the external URL's location lookup is a costly so I don't want to do it
unless
the User clicks on a link.
So in my case I do some thing like
class DownloadUrlLink {
onClick() {
URL externalUrl = getExternalURL(); //this is a costly operation, so I don't
want to do it unless user clicks the Download link.
getRequestCycle().setRequestTarget(new RedirectRequestTarget(url.toString()));
}
}
The URL points to a rather large gzipped XML file about 11MB in size.
But instead of popping up a File Save dialog, the browser starts to display the
XML file.
and CPU usage jumps up to 100%, on account of the file being this large.
Is there a way to force the browser to pop up a FileSave dialog when using
RedirectRequestTarget
