Re: testing borders with WicketTester
No, I think you misunderstood me, when I wrote about empty body I was thinking about testing, I know that border without its body works like panel and shouldnt be used in such case. I was writing about borders which have bodies, but during testing I was interested in testing such borders with some 'stub' (ie empty) body. jwcarman wrote: > > Are you sure you don't want to use markup inheritance rather than borders? > > On Sun, Nov 2, 2008 at 5:57 AM, Daniel Lipski > <[EMAIL PROTECTED]> wrote: >> >> Sorry, but I dont get your point... >> What do you mean self contained (in terms of Wicket API) ? >> >> Im sure there is a lot of user created border components which contain a >> lot >> of surrounding markup and components and it is very desireble(at least >> for >> me :)) to be able to 'unit' test such components with Wicket tester, >> regardles (i.e with empty) to border body. >> Does method Im looking for was not provided because of technical problems >> ? >> If so what is the simplest way to test border components (surrounding >> markup >> and components) with i.e empty body ? >> >> Regards >> Daniel Lipski >> >> >> igor.vaynberg wrote: >>> >>> borders are not meant to be self-contained like panels. they are meant >>> to be used within something that contains markup, eg page or panel. >>> >>> -igor >>> >>> On Fri, Oct 31, 2008 at 8:14 AM, dlipski <[EMAIL PROTECTED]> >>> wrote: Hi Is it possible (if not why?) to test Border components in a way similar to testing Panels ? -WicketTester.startPanel(TestPanelSource) ?

Re: Moving from Tapestry to Wicket?
I can vouch for the fact that Wicket's learning curve, compared to Tapestry's, is MUCH, MUCH easier for an object-oriented Java programmer. We used Tapestry at my last place of employment, and I hated it. When I left, I chose Wicket, and for the past several years have been enjoying UI development for the first time in my web app career. You can get up and running in Wicket very quickly, and can really generate some apps quickly. The biggest thing is to make sure you have a solid understanding of how to effectively use models before you begin a project - or you'll kick yourself later. I'm sure you'll enjoy your Wicket development experience - and the list is very active and friendly - let us know if you need any help along the way. -- Jeremy Thomerson http://www.wickettraining.com On Sun, Nov 2, 2008 at 10:23 AM, GK1971 <[EMAIL PROTECTED]> wrote: > > Hi Eelco, > > You are correct - right now my main worry is about development cost. > Hardware cost is cheaper IMHO than having developers struggle with a hard > framework and spending too much time trying to maintain and write code > based > around a hard framework. > > Honestly in our application (we have a roadmap for scalability) we are > likely to get several hundred concurrent sessions per server with a few kb > of state stored in the HTTPSession.

Not really, I have large chunks (containers.. actually a ListView...). I had a look at the debug output and there is one "DEBUG - MarkupCache- Markup not found: org.apache.wicket.markup.html.form.Formfi_FIhtml" and some "DEBUG - ResourceStreamLocator - Attempting to locate resource 'org/apache/wicket/markup/html/form/Form_fi_FI.html' on" or similar Most of the lines in the debug log consist of: "DEBUG - MarkupContainer- Rendering raw markup" and "DEBUG - Component - Begin render [MarkupContainer [Component id =xx" > The actual parsing results should be cached by IMarkupCache > as far as I know, so if the parsing is really the issue you > could try finding out why is the cache not working (and/or > provide a reproduceable test case in a quickstart). Can you be more specific about this? In what context should the parsing results be cached? You could try ajax-updating a large web page, say having a table with 2000+ rows, and profile it.

Do you have a lot of Ajax updates of small components without their own markup? If that is the case, then this issue https://issues.apache.org/jira/browse/WICKET-1857 might be hitting you as well and it would be interesting to see if your problem still occurs on trunk (or 1.4-RC1). The actual parsing results should be cached by IMarkupCache as far as I know, so if the parsing is really the issue you could try finding out why is the cache not working (and/or provide a reproduceable test case in a quickstart).

Try doing wicketTester.debugComponentTrees() (or debugging
the exact hierarchy by yourself).

Long component paths like this are a bit problematic anyway.
You could try digging your Form up with a visitor to make it
less dependent on the path.

Hi Uwe, this is exactly the reason why we have wicketstuff-prototype: http://wicketstuff.org/confluence/display/STUFFWIKI/wicketstuff-prototype IMHO we could use something similar for mootools.

Re: Refresh parent page from an iframe
There is an example Implementation of a file upload, that is contained in an iFrame ( http://www.demay-fr.net/blog/index.php/2007/12/07/93-simulate-ajax-file-upload-with-wicket). The Author wanted pretty much the same as you do: Alter the containing (parent) page. He uses a javascript call to the parent page. I'm not really sure if I can get all necessary steps together but here are some hints: 1) Add an AbstractDefaultAjaxBehavior to your parent page. Alter the "getCallback" method in a way that it makes a call to wicketAjaxGet and appends parameters to the query string to identify which iframe triggered the action. Take the query parameters from the current javascript scope. 2) Generate a method into the parent page that executes the getCallback script of the behavior and takes the parameters needed as function parameters. 3) append javascript to the submit button/whatever of the iframe that calls the javascript method in the parent page and pass the parameters that identify the calling iframe (maybe markup id?). 4) put java code that modifies your parent page into the AbstractDefaultAjaxBehavior's onResponse method and alter the page. That is the idea. Hope you can follow me. I'd advise you to take a closer look at the example by Monsieur Demay. Even though it contains some errors. There is a corrected version somewhere on the web. I'd say that there is no direct way using only java to solve your problem. But I've started using wicket 6 weeks ago so there might be a more clever answer :) Cheers Bert 2008/11/2 itayh <[EMAIL PROTECTED]> > > Hi, > > I have a page that contains several iframes with some actions in each > iframe.

Re: Moving from Tapestry to Wicket?
Hi Eelco, You are correct - right now my main worry is about development cost. Hardware cost is cheaper IMHO than having developers struggle with a hard framework and spending too much time trying to maintain and write code based around a hard framework. Honestly in our application (we have a roadmap for scalability) we are likely to get several hundred concurrent sessions per server with a few kb of state stored in the HTTPSession. Its not that much. What I was more concerned about was Page storage and storage that I can't control (for example, if I couldn't control IModel storage I would be concerned). We are unlikely to have spikes of traffic, but we are more likely to have dribs and drabs of users who potentially keep sessions open for perhaps minutes to hours. For our initial scaling the client will have an affinity to a specific server. We can control the number of users that we have on a server. We can then scale our servers horizontally if we hit a scaling issue on one of the servers. I'm starting not to worry about it too much. Honestly - I really face the same issues with Tapestry. What I don't face with Wicket is the development cost because it appears to be (I played with it yesterday) a very intelligent architecture. I was happy playing yesterday and even migrated our login page over very quickly. Of course I have to figure out how to handle my 'remember me' cookie and hit the database, but it all seems rather nice. Cheers, Graeme.

Are you sure you don't want to use markup inheritance rather than borders?

Re: testing borders with WicketTester
Sorry, but I dont get your point... What do you mean self contained (in terms of Wicket API) ? Im sure there is a lot of user created border components which contain a lot of surrounding markup and components and it is very desireble(at least for me :)) to be able to 'unit' test such components with Wicket tester, regardles (i.e with empty) to border body. Does method Im looking for was not provided because of technical problems ? If so what is the simplest way to test border components (surrounding markup and components) with i.e empty body ?

Ok, problem solved. I had old cookies with changed size placed in one browser. When I cleared cookies size of modal windows in both browsers are equal. Regards -- Tomasz Dziurko - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How can I format feedback messages?
Hi! How can I (centrally / per component) format the Numbers and Dates in feedback messages?

Re: Should/Could ServletWebRequest.isAjax be cached?
The profiler shows that for a (large) page, 40% of the effort (20
seconds per such particular page) goes into just parsing the tags and
does not seem to process any logic.
So, some streamlining might be in order there, even after this particular issue.
