Issue with file extensions in file Upload node


I have an issue with the file upload quick form node.  In the Webportal UI, Knime does not list files based on the file extensions specified in the node.  My problem seems very similar to the issue pointed at the following link:  File Upload node (Valid File Extensions) which I cannot access (Access denied).

Is there somebody who can help me?




Yes, unfortunately that is correct. We use Vaadin as our application server for the WebPortal and its file upload component does not support to filter file extensions in the file chooser dialog. There might be an option to do that in future releases, but for now this is an expected behaviour.
