Because my old snippet<\/a> does not work anymore for ND9 (the IBM changed the internal methods \/ objects) I had to create a new way to disable the validation of the FileDownload control. Now I have switched to a PhaseListener which waits for to any XspEventHandler<\/em> and checks if this event handler is a child of the FileDownload control. If so, it skips the validation.<\/p>\n

Here is the code for the PhaseListener:<\/p>\n
