Feed Details upload file doesnt work if template doesnt expose them to the user
Description
In the Feed Details screen you can upload a file to kick off/trigger the feed and put it in the dropzone for feeds that use a GetFile processor
This method needs to look at all properties including both the feed and the template properties and also resolve any expressions in an attempt to get the file pattern and drop location.
Currently its just using the Feed properties thus it will not work if you register a template without exposing the file pattern/location to the end user.
Environment
None
