"Upload" Action

The Upload action is created via the <UploadAction/> element within <Actions>. The Upload action allows data to be uploaded to the web application.

The Technical Process that receives the uploaded file must return a confirmation or error message. If the confirmation contains a message, the message is displayed as a pop-up window. Pop-up windows with error messages are always displayed.

The process attribute is required for the <UploadAction/> element.

In addition to the standard attributes for actions, the <UploadAction/> element can also have the following attributes:
