Set-up
I've created a custom list that fires a Workflow on New.
The Workflow uses the Collect Data from a User action. The ListItemID of the collected data (an Item in a Tasks List) is stored in the Custom list
Goal
On the DispForm of the custom list item, I want to show a preview pane of the data collected (in a Tasks list) by the user. The person view the custom list won't necessarily be able to edit the Task.
Conversely, if the Task DispForm could show the original list item that created it, that would be great, too.
Next...
Assuming all of that is doable somehow, depending on how the first data collection goes, a second one may also be initiated. Showing all three pieces of this puzzle on one page (from any of the three DispForm pages) would be a huge win!
