unable to use a!submitUploadedFiles() in site

Question

hi, 
 I am trying to use upload Files function. this is one of the step in my process. I have a final summary screen, which shows the files uploaded and they should appear as document upload link. 
 I used a!submitUploaded files in the next button, which actually goes to fIle Upload Screen to the summary screen. 
 It works fine , when I tested the interface. But shows an error in site. 
 An error occurred while executing a save: Expression evaluation error: a!submitUploadedFiles() cannot be evaluated in this environment. 
 Target folder is not Document or Folder but marked as Folder. 
 Also, editor access permissions has been given to the Users for this folder.

 Correct - it is specifically intended not to be used for interfaces in processes, since submitting a form does the same action inherently. I was hoping it would be, since it would have enabled some more advanced single-form file operations, but alas for now we're stuck with having to submit a form to deal with uploaded documents.

Harshit Bumb (Appyzie) simple interface works. Also, I recreated the folders and constants and it is working now. I have a question, if a process model is configured in site and the interface is configured as start form having file upload . will a!submituploadedFiles() work. because , this is the next step.

It won't. And you don't need that in the start form because you the user will anyway be submitting the form to initiate the process.

As stefan already mentioned - the only supported method for Tasks remains, "submit the form then deal with the uploaded file".

It sounds at first like you might have an issue with whatever you're setting as "target" in your a!fileUploadField() -- can you confirm what your configuration is here? In my working site example with a!submitUploadedFiles() in use, i have the target pointing to a constant set to the upload target folder, and the constant's type is just "folder".

What Appian version are you on, just to confirm?

Harshit Bumb (Appyzie) · Answer

It is because you can't use that function within an interface that is plugged as a UIT in a process.

Mike Schmitt · Answer

Can you clarify whether this is on a Site Page in a User Input Task? As Harshit mentioned below (but i didn't think to clarify already), this function won't work in a User Input Task (sadly), because they want us to actually submit the task and move to a new UIT to display any properties about uploaded documents.

 Well i'm otherwise out of ideas other than making sure your security settings are all aligned (user account(s), folders, etc). On the current version of Appian this should be a supported use case. I guess maybe you could try testing on a simpler interface, one with just a file upload field and a button/link that only fires the "submit uploaded files" control when clicked, and see if it gives you the same error.
