I have a dashboard where I'm using the file upload field function for the us

I have a dashboard where I'm using the file upload field function for the user to select a local file and this populates a local variable. Later on in the form I have a button widget where I then take this local document value and run it through another function. Unfortunately it seems while the document variable is getting a value the document itself isn't "committed" into the Appian CMS and this document is not actually available for other functions in the same form. Is this expected behaviour or is there something else I need to do? Snippet of my SAIL code below:

=load(
local!document,
local!target: cons!MY_TEMP_FOLDER,
..
..
a!fileUploadField(
label: "Choose File",
labelPosition: "ADJACENT",
saveInto: local!document,
value: local!document,
target: local!target
)
...
...
a!buttonLayout(
primaryButtons:{
a!buttonWidget(
label:"Process",
disabled:if(isnull(local!document),true(),false()),
...

)
)

The document won't be "committed" until you've submitted the form. A workaround is to have your button submit the form and loop back into the form after you have done your rule!processDoc(). If you chain the elements together then to the end user it would look like nothing was submitted.

@robbie Hi, until and unless the form is submitted, a temporary document id is maintained. The same is mentioned in the documentation under the file upload component.

Thanks..gotcha! So really doing this in a "single step" on one form is not doable. That's all I needed to confirm.

@robbier Yes, it's not possible as per current architecture.
