file upload without Form submission?

Question

Hi All, 
 I have a requirement to upload attachments to a target folder location and assign them before perform submit on UI screen. Is there ant way I can achieve this? 
 Thanks in advannce.

Agreed with Stewart, what do you mean by "assign them"? 
 The user will need to perform a Submit click - either button submit, or a!submitLink - but this does not mean that they need to "leave" their "current task"; if you set it up correctly, from their perspective, the user can stay in the exact same place and the only apparent difference is that their uploaded files will now be fully added into the system and available for whatever further use you needed.

Can you clarify what you're wanting to know? What's your use case, and what have you already tried, if anything? In general, what I was talking about above was having a User Input Task which, upon the click of a specific button or submit link, submits the task and chains immediately back into the same task for that user (performing arbitrary in-process work in between). In the user's viewpoint, nothing will have happened other than that their file will have been uploaded / "verified".

Unknown said: we try to use the file not available in the Appian 
 Is this after you call submitUploadedFiles() ? Can you share the code snippet of your portal form where you're trying to handle this and/or trying to call the above integration? Because AFAIK there's no expectation that the file will be accessible until it's been moved to the Appian FS.

The first thing I'd be trying here is to call the integration from within the "onSuccess" parameter of the a!submitUploadedFiles function, instead of from its own button. What happens when you try this?

The documentation seems a tad unclear on this, but I suspect having the buttonWidget marked as "submit" on the portal form is either irrelevant, or potentially harmful. Hopefully just the former. 
 The different variations you listed seem like they should cover this scenario if anything will work at all. I would note that you should definitely be testing from the Portal itself as opposed to from the interface designer (at best, both would work, but at worst, the interface designer might give misleading behavior). Sorry if this part seems obvious but you haven't specified. 
 Can you post the current state of your button code for, at least, the first bullet point? I'd like to at least verify it looks like I was thinking it should look. 
 And can you confirm also, if you leave the two functions designated as separate buttons, that it *does* correctly perform the behavior you're after, as long as you click the two buttons in the correct sequence?

Hi Mike - Thanks for your response. I made some changes and first button with "Submit: true" will save the doc in Appian & I used 2nd button to call the process model in which I configured the integration as smart service which worked

Mike Schmitt · Answer

That's a good idea. Did you happen to try putting both of those functions in the same button? I'm curious whether it'll work at this point. I expect *something* along these lines should.
