When users try to paste from clipboard in the Self Service role when creating an issue, it first asks them to save the issue to proceed. However, after saving the issue, the control does not have the option to paste from clipboard.
In Configure Application > Business Objects > Incident, select the Forms breadcrumb
Open the Incident.WebSelfService.Edit form
Click on the Attachment Control. The Control Properties will enable.
From there, you'll see a Name and Value column. Where the Name is "Allow Paste", change the value from False to True and Save.
Save the change made to the form
Refresh the browser or log in with Self Service Role again and open any existing active Incident
You should now be able to paste
