Paul's Domino XPages Stuff

In response to: XPages - Exceeding max file upload size - Can it be prevented?

There are a couple of things you'll need to do to enable your XPages Application and Domino server to handle bigger attachment sizes above 1mb.

You'll have to configure in the xsp.properties file for the XPages runtime (xsp.upload.maximise=), or per application through the same file, Application Properties and set the File Upload Options
You'll also have to set a higher level the HTTP stack accordingly if the size is above 10Mb. This is configurable in the Server document using the Admin client. I think that this is the 'Maximise POST data' on the Internet Protocols\Domino Web Engine tabs.

And to get the error message returned to the user when they're attempting to upload an attachment that exceeds the upload limit add a 'Display Errors' control to your XPage. If you are happy with the current or default upload limit then this is all you'l have to do.
And if that doesn't work, it's a bug.
