I have a project to upload some files for both licensed users and portal users. Got it working 98%... except for portal users.. mama mia...
I created a site off a domain, logged in a user and inserted a ContentVersion by API, and also an Attachment, both in JavaScript, and the ContentVersion appears in salesforce classic chatter, and the attachment in an account related list. However, ideally, I want to insert just Attachments, but when setting Parent Id in JavaScript, an exception is thrown using the API for portal users: Attachment: Bad Field names on insert/update call: ParentId.
I read recently that API calls are now restricted for attachments, and we cannot insert attachments for portal users, as witnessed by the exception. Is there some way I can let a portal user upload an attachment so a ParentId can be set? (In my case, set to an account record.) Need I try sending attachments as an email and make a trigger on emails received to insert an attachment?
Function UploadFile(parentId) is called from an onclick commandlink. variables {!sessionID} {!username} {!password} and {!parentAccountName} are set in prior pages. The !sessionID is a session ID generated by logging in on a prior page using SOAP, but when I get to here and try to insert, error says session invalid, so I've logged in on this page too, but using the API to get a session... If a local user is using my forms, no problems, meaning not required to login to API AND I can insert an attachment like I like instead of inserting a VersionContent.
