Custom Content
I'm attempting to load the markup for a page based on values that are available when the page is constructed. For example, I want to be able to pass a parameter into a page and then lookup the name of the content file in my database based on this parameter and then have the page load and display the appropriate content. I've tried looking at the custom resource loading example in the examples package but that seems to work by loading content based on the class name and I didn't see a way to extend it. I've tried overwriting the newMarkupResourceStream method, but it seems to be called before the constructor is called as well as before the session is available. Any suggestions? j

What is the content file you want to display? Is it just HTML? If so, try: String html = myBusinessMethodToGetContent(someParam); add( new Label(customContent,html).setEscapeModelStrings(false) ); -- View this message in context: http://www.nabble.com/Custom-Content-tf4619447.html#a13192982 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Custom Content
Will that work if the content includes a form? I would like to be able to have a page which includes a form but have a couple of different versions of the HTML and be able to select the one I want based on the param... In otherwords the HTML will contain form elements with wicket:id attributes which I want to be associated with elements I've added in the form class. The reason is I want to have radically different layouts for a page/form which I don't want to have to update any java code to enable, only add the new HTML file and update my database. Swapping in different style sheets which would seem to make the most sense isn't going to work in this case.. j On 10/13/07, Igor Vaynberg [EMAIL PROTECTED] wrote: stick a content into a label and call label.setescapemodelstrings(false) -igor On 10/13/07, Jeremy Levy [EMAIL PROTECTED] wrote: I'm attempting to load the markup for a page based on values that are available when the page is constructed.

Re: Custom Content
see IMarkupResourceStreamProvider and IMarkupCacheKeyProvider. make that page implement both and suck the markup in from the db. -igor On 10/13/07, Jeremy Levy [EMAIL PROTECTED] wrote: Will that work if the content includes a form?

Re: Custom Content
Igor, I was afraid you were going to say that, we are still on 1.2.5 and I think those are 1.3 features :(. We aren't planning to upgrade until it's released. Can you think of any alternatives? I've divided the entry page and the form page into two separate pages, the first page figures out which html file to use, stores it in a static hastable somewhere else, using the sessionid as the key and forwards to the page that loads the HTML file. ( I know thats very unwickety, not to mention hacky). I then load the value out of the hashtable in newMarkupResourceStream and that works. Only issue is that newMarkupResourceStream is only called on the first time the page loads when it's compiled with the HTML i suppose. Is there any way to prevent that for one class / page?

Re: Custom Content
Thanks. I see, so if I were to return a random value with getVariation, that would effectively defeat reusing the complied version. Could you give me more details on markupresourcestreamprovider I couldn't find anything like that in the api, what should I extend / implement and how do I use it? j On 10/13/07, Igor Vaynberg [EMAIL PROTECTED] wrote: On 10/13/07, Jeremy Levy [EMAIL PROTECTED] wrote: newMarkupResourceStream is only called on the first time the page loads when it's compiled with the HTML i suppose.

Re: Custom Content
Okay, I think i figured it out. Using AbstractResourceStream which gets content based on the ids. Thank you. On 10/13/07, Jeremy Levy [EMAIL PROTECTED] wrote: Thanks.
