I am looking for a way to set custom forms in Share to be read-only for general users, but to allow them to be edited by administrator level users. At the moment I am using the "read-only" = true argument in my form field in the share-config-custom.xml, which achieves the first part of my goal. However, I'm still looking for a way which the admin could override this and make changes to those form fields, if necessary.
Re: Admin override for read-only form fields in share
The only way I can think of at the moment would be based on Surf Extension modules. Such an extension can be bound to specific conditions via an evaluator (in this case checking group membership / role against being admin) and provide overrides to configuration sections. In such a module you could provide a reduced set of form cofiguration directives that changes the read-only attribute.
