Re: [Wicket-user] Setting up directories to make CSS available
You can include wicket:remove base href=file:///C:/Docs%20and%20Settings/you/your-project/src/webapp/ / /wicket:remove in your html head. 2007/3/14, Chris Colman [EMAIL PROTECTED]: I'm using wicket and trying to work out how to set up my directories so that while editing HTML markups my HTML editor has access to the same CSS files that will be used as run time. The HTML markups are in my project/src/com/sas/ui/wicket directory with my wicket component classes but being in the src directory these files are kind of in a different realm to the normal HTML resources of the web app. Any ideas on how to set up directories so that I can use the CSS in both my HTML editor and at run time? - Take Surveys.

[EMAIL PROTECTED]:One weekend later and I'm working on this again.Here's my situation:

target.addComponent(theCartPanel);ModalWindow.close(target);}My problem is: how do I get access to the cart panel from within theform in the modal window?Here's what I've come up with, and
everything feels a bit ugly:1. I can get the cart from the session and have the cart fetch thecart panel -- ugh, the cart (business object) shouldn't know about aUI widget.2.I can pass the cart panel in as my model object
3. I could put the cart panel in the session (or my own ThreadLocal)4. I could crawl my way back upfindParent(ProductPanel.class).visitChildren(IVisitorThatHandlesTargetAddComponent)Any suggestions would be entirely welcome.

What I am working on now, we have a reportmodel and almost all our pages has aconstructor that requires our reportmodel, so we dont need to be aware of session.
I feel that the application becomes more simple that way, however we do not have a LOT of panels, we have some which uses abstractmodels that grabs their data from the reportmodel, when switching pages we pass the
reportmodel through. This might be a different approach from what you need when building a store site, but it feels pretty a lot simpler than have something stored in session context.

If you're main domain is a store, and a cart is information you want to keep throughout, it does make sense to put it in a session, so that you don't have to pass it around your pages and panels all the time.

Erik,did you search this link?http://www.virtuas.com/articles/webframework-sweetspots.html -Dirk2006/9/26, Erik Brakkee [EMAIL PROTECTED]: Hi all, A collegue of mine at a very big and slow organization is evaluating web frameworks, of which one is wicket. As expected, there is the remark that wicket is not scalable because of its use of session scope. I already gave the most important arguments, but it would be nice to have some good links for backing these arguments. In paticular, the link where (I think it was Eelco) mentioned that in a number of comparisons between web frameworks it was shown that wicket actually stores less in the session than other frameworks. This is a really strong argument, especially when backed up by real data. Nevertheless, I couldn't find this information anymore. Are there links to the applications (downloadable) proving this point? Cheers Erik -Take Surveys. Earn Cash.

Hi Michael,
you need an AttributeModifier. Something like
protected void populateItem(final ListItem listItem) { add(new Label(name,Scooby).new AttributeModifier(id, ..,
new Model(row + listItem.getIndex()));
}

Hi,I want to be able to render id=rowcount attribute when using ListView. I need it to code _javascript_ using getElementById(). Please find the examples below:
Html code:---tabletr wicket:id = rowToRender id=row0 tdspan wicket:id=namename/span/td/tr
tr wicket:id = rowToRender id=row1 tdspan wicket:id=namename/span/td/trtr wicket:id = rowToRender id=row2
tdspan wicket:id=namename/span/td/tr/tableJava code:---add(new ListView(rowToRender,someArrayList){
protected void populateItem(final ListItem listItem) { add(new Label(name,Scooby);}});Has anyone done this? Any help wo uld be greatly appreciated.BTW, I 'm using Wicket
1.1.1.Thanks in Advance.--Michael

[Wicket-user] Multiple page instances possible?
I am using latest anon cvs head. I have a home page H with a popuplink opening page P. It is possible to have more than one page P. A linkon Pleads to P, itonly changes internalpage state.Thus we can havesequences like: H - P1 P1 - P1 +-- P2 P2 - P2 P1 and P2 have different internal states, because the page constructor takes the new internal state as an argument. The sequence H--P1, H--P2, P1--P1, P2-- shows the expired page. (In step 3 version 0 of P2 is removed from the wickets page map) How can I have multiple instances of page P? Dirk

Re: [Wicket-user] Multiple page instances possible?
I try to explain. Given the above code with homepage H und page class P.
We have the following steps:
1.in my homepage I click on the action link giving me a new browser window for class
instance P1 of class P
2.in my homepage I click again on the action link giving me a new browser window for class
instance P2 of class P
3.in P1 I click on the link
4.in P2 I click on the link and then I getthe standard wicket page expired page
As far as I can see, wicket is removingversion 0 of page P2 from the page map in step 3. when PageMap.access() is called.
I hope I could make it clear.

Re: [Wicket-user] recommend HTML editor for Wicket user
2006/2/14, Martijn Dashorst [EMAIL PROTECTED]: Frank,There are several options. But by far the best one is use a plugin foryour IDE. NetBeans and IntelliJ IDEA both have very decent markup editors, with tag completion. Eclipse has a couple of plugins ofvarying quality. You might want to check out the WTP package.Eclipse has a built in browser, but I tend not to use that, as it getsin the way of editing the file. As I am rather fluent in HTML I usually know what the final result looks like.A very nice workflow is to start Wicket using Jetty launcher, anEclipse plugin, and run your application in development mode (in yourapplication constructor do: configure(development); This will instruct Wicket to scan for resource updates and will reloadyour markup as you change it and press the save button. If you run indebug mode, Eclipse will try to hot swap the code as you change it in your application. So you can update that behavior of the onclickmethod of your button and links!If you don't mind paying a minor fee, you could see if MyEclipse works for you.I don't have other preferences. For basic editing stuff on a windows box I use UltraEdit. Probably the best plain text editor around. If you are looking for a free editoruse PSPad. Martijn Dirk On 2/14/06, Frank Silbermann [EMAIL PROTECTED] wrote: I am not only new to Wicket; I am also new to web programming.I can read HTML, but I'm not fluent in writing it.Any suggestions for a free HTML editor that is appropriate for Wicket users? I presume it should be text-centric rather than a WYSIWYG editor, because we need to keep things clean, small and readable at the tag level.But it would probably be nice if there were a way to view the result at the touch of a button.Also, it should make it easy to produce correct XHTML, especially for someone who has trouble remembering the names of tags.--Living a wicket life...Martijn Dashorst - http://www.jroller.com/page/dashorstWicket 1.1.1 is out: http://wicket.sourceforge.net/wicket-1.1 ---This SF.net email is sponsored by: Splunk Inc.

Frank,I see your confusion (I think).The javadoc comment for the modelObject parameter says:
'The model object, which may or may not implement IModel'This means that you can use POJO's directly as a parameter, and,IModel objects that wrap an object.For instance, you can do this:
new PropertyModel(new Person(), name);andnew PropertyModel(new Model(new Person()), name);Both property models will evaluate correctly to the name propert ofthe person object. The difference is, that the first property model
uses a direct reference to the person object, and the second uses awrapped person object.The advantage of the latter is that you can use specialized modelsthat minimize HTTPSession usage, by retrieving the model object
'on-the-fly', and still use the property models to get to the values.The other big advantage is that you can use this in your forms:public MyForm(String id, IModel personmodel) { super(id, personmodel);
add(new TextField(name, new PropertyModel(personmodel, name)));}This has the advantage that you don't need to know how to get at theperson object in your form component. It can come from everywhere.
