I am trying to use the DisplayAttachFile action on click of a hyperlink in a modal created during the click action a create MI button.

When the user clicks on the create button to create a new case, the system is searching by memberID and LOBState and filtering cases in the last 7 days to create a list of recent cases for the member to avoid duplication.

The RD that populates the list also displays the name of the initiating document and there is a hyper link next to document name to view the document. This is the hyperlink that has the run activity DisplayAttachFile.

I can see in the tracer that the DisplayAttachFile is running, but the popup that shows the download does not appear.

Does anyone have an explaination for this? When I run the activity from Dev Studio it gives identical tracer output but also displays the pop up I would expect.
