I have looked at the DownloadLink class and it does seem to do what i need.
The issue I have now is that I am using a link tree which uses ajax to load the
directory contents as the tree is traversed. This works fine.
What I think I need to do is change the behavior of the tree node for the files
such that it does not use ajax. I have looked at doing this but just cant work
it out.
I have extended LinkIconPanel to determine if the node is a directory or a file
depending on the type of the user object in the model and not on if the node
has any children.
I think this is were I need to make changes but I cant find out where the ajax
behavior is being added.
The code I have derived from DownloadLink is
IResourceStream resourceStream = new FileResourceStream(new
org.apache.wicket.util.file.File(file));
getRequestCycle().setRequestTarget(new
ResourceStreamRequestTarget(resourceStream) {
public String getFileName()
{
log.debug("returning: " + fileItem.getFileName() ) ;
return fileItem.getFileName();
}
});
I have this on the onNodeLinkClicked of my tree (extends LinkTree).
To my understanding the download redirects the request to the file to be
downloaded, dont think this will work with an ajax request.
