Happy new year everybody :),
Setup: Wicket 1.3.5
Situation:
I have a DynamicImageResource subclass that is mounted as a shared
resource. Based on a request parameter it returns a dynamic image.
Besides that there is a subclass of Image that points the Image
to a ResourceReference with a parameter in a ValueMap that indicates
the image that need to be loaded by the shared image resource.
What works fine:
Accessing the shared resource under /images?name=blabla.jpg works fine.
Problem:
When I point an Image to a resource using a ResourceReference with
a ValueMap having "name" it creates a URL for the image like
../images/name/20090102130806-402427017.jpg/
My DynamicImageResource however seems to expect "normal" URI parameters.
It is not able to find the "name" parameter when using the URI as created by
Image.
Code summary:
public class ImageResource extends DynamicImageResource {
...
public static final Object PARAM_IMAGE_NAME = "name";
private ThreadLocal<String> imageName = new ThreadLocal<String>();
private ExtranetApplication application;
@Override
public IResourceStream getResourceStream() {
String imageName = ((String[])
getParameters().get(PARAM_IMAGE_NAME))[0];
this.imageName.set( imageName );
return super.getResourceStream();
}
@Override
protected byte[] getImageData() {
// get byte[]
byte[] res = ....
return res;
}
...
}
Application.init() :
getSharedResources().add(
ImageResource.IMAGE_RESOURCE_NAME, new ImageResource() );
mountSharedResource("images",
new
ResourceReference(ImageResource.IMAGE_RESOURCE_NAME).getSharedResourceKey() );
And the usage to fill an Image object:
public class ImageDisplayer extends Image {
public ImageDisplayer(String id, String image) {
super(id);
ValueMap parameters = new ValueMap();
parameters.put( ImageResource.PARAM_IMAGE_NAME, image);
setImageResourceReference(
new
ResourceReference(ImageResource.IMAGE_RESOURCE_NAME), parameters );
}
}
usage: new ImageDisplayer("id", "imagename");
The <image> src-attribute is rendered by the ImageDisplayer as:
../images/name/20090102130806-402427017.jpg/
Causing the ImageResource to be unable to find the name parameter.
I don't have an explicit URL Encoding Strategy configured.
Is this a bug or a feature, is there a work-around?
Thanks a lot,
Janno de Wit
