I'm trying to populate a Data Field with the contents of a resource file. I see the "Uploaded Data Resource" option in Composer that seems like it would do what I'm trying to do, but I can't get it to work after deploying to TM (It works when previewing). Has anyone ever gotten this feature to work or know how it's supposed to work?
In the upcoming 4.4.1 release we are adding a new option to support this. It will require upgrading your organisation to use 4.4 Service Pack 1 however for you to be able to use it
You can upload the contents to the data field and it will work in preview but the issue you are seeing is due to a limitation in Composer. When we generate the seed XML for the form that is passed to TM as a starting point for for the pre-fill service, this data is not included in the seed. When the data is merged into the field at form start the blank element will override the value stored in the form. There are two options to work around this:
Not all files types are supported by the upload button in the Property editor. Please ensure you've uploaded the "Other" file types from the organization resources tab to ensure they are recognized as the proper extension types.
