The shopping cart use case fills a user's task with documents and provides the documents to the user in a single panel. Then, the user starts the shopping cart task manually.

if documentNotInRepository then
  createDocument()
end if

findPanel() // for example by name

if PanelNotFound then
  createTask()
  createPanel(task)
end if

modifyTaskInputList(panel.taskId) // add document to task
