Sorry... I thought it requires the creation of form input or patching the
SF, so I asked it here.
Thanks for the way, but it will not work for me because:
1) we will probably have 50-100 servers
2) each of the servers will have lot's of files: sometimes several
terabytes of 10M images. That's a lot.
3) I've used the example for the file server and it's my current need/
However I'm very interested in a generic API calls from withing the
semantic form when we put some data in the form and sending the ajax call
to an api with our current field values as the parameters.
for now I will try to solve this with javascript extension that listens the
blur() action and the REST-API that is responsible for delivering the
information
