Issues with DWA
I am working on a cloud-based solution using DWA (v7.1.10). I am running into the following issues, and if you can provide assistance I would appreciate hearing from you.
- Upon clicking the link provided in the email generated by the Assignment, a browser window appears with the PerformExternal harness, but the underlying error message says ' Access Denied. This request for information cannot be processed (Session state is invalid).' I have verified:
- The user profile is named External (in the SMA, it shows up as 'External-ExternalUserName',
- The user profile contains a password and the appropriate Access Group.
- The Case does not show any open assignments. However, the Assign-External class contains an instance that corresponds to the assignment I expect to see in the case.
- I am attempting to use DWA as a 'one-click' solution, whereby the user's response is the equivalent of clicking Submit on the Perform Harness (in other words, they are accepting the default Flow Action for the Assignment, and the only response they should see is the Confirmation Harness). I attempted to use AutoClose, but the expected action is not performed. I can trace the action, and all the parameters seem to be in order, but no action is performed on the case.
I look forward to your responses.

An update: My workaround exploited a 'feature' of 7.1, and upgrading to 7.2 changed the behavior. I eventually replaced the DWA link with a REST URL (my own version of the /assignment API), and the behavior was much more consistent and reliable.
Hi Joel,
This may or may not help you, but this is something you should be made aware of.

That article is a little hard to understand, but the point to take away is you will want to be cognizant of the pxThread.pxReqURI property for users clicking on the DWA link vs the public link URL

An update:
- Another developer discovered that the assignments did not display due to a missing access of role to object
- I created my own DWA insert that combined the pySignature value with a custom Activity rule that acts as a wrapper for PerformAssignment. So my non-user receives an email with a link that performs an action on a single click.
