DynamicWebResource & ResourceState acting strange in 1.3
About 2 years ago (yeah, wow!) someone on this list helped me figure out how
to load external images onto my pages and it worked perfectly, until I
upgraded to 1.3.x from 1.2.4. I don't know much about the internals of how
it works, it's a lot of code, and I really didn't care how it worked, it
just did!
Now that it's broken due to the upgrade, I'm trying to figure out what's
going on and I think I've pinpointed where it's failing.
The class signature looks like so:
public class ImageResource extends DynamicWebResource
...and in there is a method that gets the ResourceState:
protected ResourceState getResourceState()
In there, I get the params:
ValueMap params = getParameters();
byte[] data = null;
String imageId = params.get("file").toString();
System.out.println("IMAGE ID: " + imageId);
if (imageId.contains(PropertyProxy.getExternalImagesRoot()) ||
imageId.contains(PropertyProxy.getExternalImagesAltRoot()))
System.out.println("YES! - STRING CONTAINS IMAGE ROOT CONFIG
PROPERTY!!!");
else
System.out.println("NO... - STRING DOES NOT CONTAIN IMAGE ROOT
CONFIG PROPERTY.");
So with this, I could make a call in a Wicket page like so:
//get reference to Application's ResourceReference
ResourceReference imageResource = new ResourceReference("imageResource");
//build URL of image from file
String imgUrl = RequestCycle.get().urlFor(imageResource) +
"?file=C:\\MyApp\\assets\\images\\category\\Bundles.jpg";
add(getContainer("bundleThumbImg", "src", imgUrl));
However, now the "file" parameter can't be cast as a String, strangely
enough, I get this output when running what I showed above:
IMAGE ID: [Ljava.lang.String;@25249a
NO... - STRING DOES NOT CONTAIN IMAGE ROOT CONFIG PROPERTY.
This is where everything breaks down for me. I expected (and always got in
Wicket 1.2.x) the actual value of the "file" param in the URL shown above.
Can anyone offer any advice?
Thanks!

Imageid is a array it seems, dont just call to string on it check if
it is an array and get the first element
