Re: [Wicket-user] Multiple page instances possible?

I will try the first method. The eviction strategy has to wait until I have enough wicket knowledge.

Thanks to all of you.

solution would be for you to open those windows in different pagemaps.

ala: page.forName(String.valueOf(Math.random());

this will cause more session state to be kept, but i dont see any other solution. maybe a PageMap eviction strategy :)

Now that we have an explanation, what's the solution?

2006/3/10, Johan Compagner < [EMAIL PROTECTED]>:
ahh yes
thats logical.
Because you use the same pagemap.

and a pagemap has a browser stack
so if you open P1 on pagemap X
then P2 on pagemap X

and you click again on P1 then we think you did a back button to P1
and then we remove P2 from the stack because if this was a browser it wasn't accessible anymore.

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 get the standard wicket page expired page

As far as I can see, wicket is removing version 0 of page P2 from the page map in step 3. when PageMap.access() is called.

I hope I could make it clear.

then i need a complete example to see what really does happen or what exactly goes wrong.
At what exact time you get and error and what exactly is that error?

I am using cvs head.

I do not close any window P1 or P2.

My homepage constructor in full glory:

   public Home() {
      Link actionLink = new Link("start") {
         public void onClick() {
            setResponsePage(new P());
         }
      };

      PopupSettings p = new PopupSettings( PageMap.forName("popup-page-map"),
            PopupSettings.LOCATION_BAR );
      p.setWidth(600).setHeight(600);
      actionLink.setPopupSettings(p);

      add(actionLink);
   }

My class P is basically something like:

        .....

       Link link = new Link("link", new Model(..)) {

               public void onClick() {
                  changeInternalState(getModelObject());
               }

       ......

ahh which build are you using?
Because i think this is the problem i fixed and i believe it didn't make it into 1.2b1

The popup closing did remove to much.

Don't know exactly if that is the case for you then i have to see more code.
that link that you give those popupsettings to is that a link with an onClick() {setResponsePage(newPage)} ?

Yes, see above.

I have one homepage H with one Link named actionLink:

      PopupSettings p = new PopupSettings(PageMap.forName("popup-page-map"),
            PopupSettings.LOCATION_BAR );
      p.setWidth(600).setHeight(600);
      actionLink.setPopupSettings(p);

In my homepage I click two times on this link, giving me 2 browser windows P1 and P2.

Ah,

you have 2 browsers pointing to the same session?

Then you should use a different pagemap for each browser.
