Dynamic Markup?
I am writing an open source Wiki component for Wicket.. http://sourceforge.net/projects/wicketwiki I've recently started it so it is still in the development process. I want to make it work completely off of AJAX in order for the component to be completely autonomous without effecting the other components it could be grouped with inside an application. Right now, all it does is allow you to edit/render a single wiki page with no interwiki links. I accomplish this by simply just using a Label and not escaping the HTML that is rendered from my wiki engine. The problem is that if I want interwiki links I'm going to have to be able to dynamically create and add AjaxLinks from the rendered HTML markup coming out of the wiki engine. I need a way that I can create my own Markup file/stream/whatever and have my custom component use that dynamic markup instead of searching for a valid .html file in the classpath. Does anyone know what I should look into? Brian Gorman

dynamic markup and components
Hi everyone,
I want to load some markup stored in a string, this markup also has
references to wicket components that I need to create and then add to
whatever will contain the markup. Is this possible and how can I do this?
private static String getHtml() {
String html =
"" +
"my text" +
"" +
"" +
"";
return html;
}
Cheers,
Alinoor

Hi Sven, I came across this stackeroverflow link and tried it but couldn't get the markupcontainer to load the markup. I'll give it another go...

Re: dynamic markup and components
Hi,
I don't know if you might find this helpful, but if your component must
generate a different markup from request to request, you should
implements interface IMarkupCacheKeyProvider to avoid markup caching:
/**
* Must return null to avoid markup caching
*/
@Override
public String getCacheKey(MarkupContainer arg0, Class arg1) {
return null;
}

Dynamic Markup Content in Wicket (1.4+)
Does anyone have an article on how to add dynamic content such that the content isn't defined in the markup at compile time. It is generated at runtime. For example. Old Way - Listing1 ... With dynamic content - Listing2 ... I could use an offline, compile time tool to generate the markup and then add it to my project. But I wanted to see if there is something more dynamic. I also, could use something like a ListView or Repeater, but I wanted to avoid that because of legacy java code. The Java code is structured such that 'containers' has sub-components 'container1' *** It is easier refactor the Java code or have some system to add some kind of dynamic content that would look like the HTML in Listing1. UseCase: For Igor, The use-case is just as I described, there are some cases where you have legacy Wicket Java code. It costs more to modify the Java code and retest the logic so I wanted to be able to 'refactor' my markup and clean at least the markup without making major changes to the Java hierarchy structure. I want to have a HTML markup that looks like this but would act like the listing in listing1 above.

Re: Dynamic Markup Content in Wicket (1.4+)
any component can implement IMarkupResourceStreamProvider and return whatever markup it wants wicket to use. If you need a fine-tuned control over the caching mechanism for this markup you can also let your components implement IMarkupCacheKeyProvider. -igor On Wed, Sep 28, 2011 at 8:05 PM, Brown, Berlin [GCG-PFS] wrote: > Does anyone have an article on how to add dynamic content such that the > content isn't defined in the markup at compile time.

Dynamic markup loading & caching in base page
Hi *,
We built an app which has a base page, and several child pages which
inherit from the base page.
The app is themeable, and one of the requirements of the app is/was that
these themes should be manageable.
This means we have a set of themes which can be changed on-the-fly.
To add flexibility to our app, a theme can override the html of the base
page.
To handle the custom html, our base page implements
IMarkupResourceStreamProvider and IMarkupCacheKeyProvider.
Every user of the app can select a theme, so the theme is determined per
request.
The cache key is generated based on the theme id and the container class:
@Override
public String getCacheKey( MarkupContainer container, Class< ? >
containerClass )
{
final Theme theme = getWebsite().getTheme();
return "Theme#" + theme.getId() + "-" + containerClass.getName();
}
The markup resource stream is only "overriden" for the base page:
@Override
public IResourceStream getMarkupResourceStream( MarkupContainer
container, Class< ? > containerClass )
{
final Theme theme = getWebsite().getTheme();
if( containerClass.equals( WebsiteLayout.class ) )
{
String markup = theme.getMarkup();
return new StringResourceStream( markup, "text/html" );
}
return defaultResourceStreamProvider.getMarkupResourceStream(
container, containerClass );
}
(where defaultResourceStreamProvider is a
DefaultMarkupResourceStreamProvider instance).
The problem we are facing is that when the user switches to a different
theme, they keep seeing the html code of the previously selected theme.
Debugging shows that when the theme is changed:
- getCacheKey is hit for both the child page and the base page
- getMarkupResourceStream is hit for both the child page and the base page
I think it could be due to the way wicket's
DefaultMarkupResourceStreamProvider handles inheritance: maybe it (too)
caches the base page markup?
Can anyone help with this? How do we properly cache dynamic html for a
base page which is used by several (static) child pages?
Thanks!

Re: Dynamic markup loading & caching in base page
Sorry, I forgot to add that this is a wicket 1.5 app.
As a quick follow-up, after looking at the InheritedMarkupMarkupLoader,
I see that it delegates loading of the parent (base page) markup to the
MarkupFactory.
I think that means that our current setup should work, when it doesn't.

Re: Dynamic markup loading & caching in base page
Another hour of debugging revealed the problem...
The MarkupCache method loadMarkupAndWatchForChanges has code which
shortcuts our custom cache key:
// get the location String
String locationString =
markupResourceStream.locationAsString();
if (locationString == null)
{
// set the cache key as location string, because
location string
// couldn't be resolved.
locationString = cacheKey;
}
Since our child pages are loaded through wicket's default resource
loading mechanism, a MarkupResourceStream instance is used.
The MarkupCache has a level of indirection:
cacheKey => locationString
locationString => cached markup
Since our child pages' markup resource stream have a location on disk,
this effectively means wicket caches the actual content only once
instead of per theme: all our custom cache keys point to the same
location string.
The fix was easy: I created an IResourceStreamWrapper class, and let it
wrap the MarkupResourceStream of child pages. This effectively makes
them return a null location string, and thus the child pages are cached
per theme.
