I'm trying to send a redirect, but I keep getting a NullPointerException
from somewhere in the depths of Tapestry. Firefox does actually
redirect correctly, but still I don't like the exception being thrown.
Anyone have any ideas? Thanks.
The Java code in my page class looks like this:
@Inject
private Response response;
public void pageAttached() {
try {
response.sendRedirect("http://www.timkoop.com/";);
} catch (IOException e) {
System.out.println("redirection exception");
e.printStackTrace();
}
}
Part of the stack trace is this:
[ERROR] TapestryModule.RequestExceptionHandler Processing of request
failed with uncaught exception: java.lang.NullPointerException
java.lang.NullPointerException
