unsupported value type of class org.openforis.idm.model.FileAttribute

Dear user,
If the file attribute in your survey is marked as multiple, then it won't be supported by Collect Mobile; you will have to "wrap" it inside a multiple entity if you need to add more files. In that case, you can also take advantage of the wrapping entity by adding some more attributes, like a file description, remarks, etc.
Many thanks,
Open Foris Team
