Re: Calls to MarkupCache#putIntoCache does not use the key provided by MarkupCacheKeyProvider

[Edvin Syse]

Hi Johan,

OK, so I need to override the LocationString to also include my unique 
prefix somehow? Where should I do that?

put into cache gets the LocationString not the markupCacheKey
Because MarkupCache uses 2 maps

CacheKey->LocationString
LocationString->Markup

so that we dont get multiply markup objects for the same markup file.
(location)

Hi,

I have a virtualhosted CMS written in Wicket 1.3 where some of the pages
are loaded from the database. This is done using a custom
ResourceStreamLocator, configured in the Application#init method. This works
good.

Different users have different templates loaded for the same Wicket page,
so I need to provide a custom cache key so that instance #2 doesn't get the
template loaded for instance #1. Therefore I have overriden the MarkupCache
class to be able to override the MarkupCacheKeyProvider. This also works, my
CacheKeyProvider is consulted, but not always used for
MarkupCache#putIntoCache(). Shouldn't the key returned from the
CacheKeyProvider always be used when calling putIntoCache()?

Here is my MarkupCache implementation:

public class TornadoMarkupCache extends MarkupCache {
  private IMarkupCacheKeyProvider markupCacheKeyProvider;

  public TornadoMarkupCache(Application application) {
      super(application);
  }

  protected Markup putIntoCache(String locationString, Markup markup) {
      System.out.println("Putting " + locationString + " into cache");
      return super.putIntoCache(locationString, markup);
  }

  public IMarkupCacheKeyProvider getMarkupCacheKeyProvider(MarkupContainer
container) {
      if (container instanceof IMarkupCacheKeyProvider) {
          return (IMarkupCacheKeyProvider)container;
      }
            if (markupCacheKeyProvider == null) {
          markupCacheKeyProvider = new TornadoMarkupCacheKeyProvider();
      }

      return markupCacheKeyProvider;
  }

}

And here is my CacheKeyProvider:

public class TornadoMarkupCacheKeyProvider extends
DefaultMarkupCacheKeyProvider {
  public String getCacheKey(MarkupContainer container, Class clazz) {
      String key = TornadoSession.get().getInstanceId() + "/" +
super.getCacheKey(container, clazz);
      System.out.println("Setting key " + key);
      return key;
  }
}

I typically see things like this:

Setting key 1/no.sysedata.wicket.components.InfoPanelnohtml

Putting
file:/C:/Users/edvin/projects/tornado/target/classes/no/sysedata/wicket/components/InfoPanel.html
into cache

.. so it seems the CacheKeyProvider is consulted, but the key is not used
for MarkupCache#putInfoCache()

Can someone point me to what I'm missing?

Thanks!
