4.0 Multi File Upload Disrespects Validation Rule

Unknown

I have a validation rule checking if a multi file upload component has any uploaded files.
The validation works when the form first shows, and also works when the user adds a file.
But when the user removes all uploaded files then the validation rule still thinks there are files in the component.

I know I could apply "Required Outcome Scenario" to this component - but Im not using a regular button(using Sub Dialog button) so I need a Validation Rule.
Is this a bug?

This is a known error and is resolved in version 5.0 and above.
As version 4.0 of Decisions is no longer in active development we are only accepting requests regarding the stability of this release.
Due to this reason you will need to upgrade to 5.0 or later for a resolution utilizing a Sub Dialog Button.

You could replace the Sub Dialog Button with a regular Button and apply the Required Outcome Scenario to this component, and then have this buttons outcome path in the flow loop back to the form, resembling Sub Dialog behavior.
