I have attempted to use the MAFileUploadComponent slightly more manually than usual. e.g. getComponent ^ widget childrenCache at: {item. field} ifAbsentPut: [ (field componentClass memento: (MAStraitMemento model: item description: field) description: field parent: widget). ]. However, the value returned to the callback is the filename string, rather than the file itself. I feel I am missing something somewhere, any ideas what it might be? Keith
