APEX

In the past I've used procedures with the wpg_docload.download_file function to download files by granting public to the procedure and executing the download from a report link (such as http://localhost:8080/apex/schema_name.download_blob?file_in=xxx)

I'd like to move to the download to a link that's called from an ajax called on demand process. Is this possible? I have got the report link calling a javascript function passing the rowid in and running the same download_blob procedure via the on demand process but, whilst the code runs OK it does not return the prompt box for the user to open/save the file. I guess this might be because it's not returning it to the javascript in the proper way but I'm v flaky wrt to ajax.

var ajaxRequest = new htmldb_Get( null , &APP_ID. , 'APPLICATION_PROCESS=download_blob' , 0);
var ajaxResult = ajaxRequest.get();

Thanks
