This may be a trivial issue but I've been struggling for hours to get Quickforms to work in the WebPortal. I am running Knime 3.3.2 and Server 4.4.2. Whatever I do with the simplest workflows (say conversion of Excel to CSV, as described on page 4 in https://download.knime.org/server/4.4/KNIME_Webportal_User_Guide_4.4.pdf), the WebPortal just executes the workflow without ever asking for an input file. Encapsulating the Quickform nodes into Wrapped Metanodes makes no difference.
What am I overlooking?
