To disable to validation you can use this little SSJS snippet which sets the „disableValidators<\/em>“ property for all events of the UIFileDownload<\/em> control. Just add the following code to the beforeRenderResponse <\/em>event of your XPage and change the id of the component to fit your requirements.<\/p>\n
