Passing question variables, etc, as part of the URI when moving from the STACK dashboard to the CASchat page can cause an Apache error if the URI is too long.
There doesn't seem to be a good way of sending a POST request within Moodle that I can find, though. I tried a hidden form but that led to problems making the link look right. Instead, I've saved the quba (required for images showing on the dashboard anyway) and just passed the required info to load the question/attempt data on the CASchat page.
