Too much overheard and potential user complaints to split the tasks into 2 to try and accomplish this goal. After review of the process where this is feature is required the Info Required option is rarely if ever used. So we made a decision that going forward it won't be allowed to be use. So I removed the behavior from those tasks that will use the transition condition and the only available choices for selection are now statuses that complete the task, none of which they are allowed to select without the Risk Survey. It doesn't help me for future use cases but it'll suffice for now.
I can't trigger on the Risk Updated activity because its set by default to Medium and may stay that way depending on how the Risk Survey is filled out.
However, what I have done is added a trigger to a MOD file that checks for the insertion of a new Risky Survey like this...
MODIFY risk_svy POST_CI zcheck_risk(id,chg_id) 2000 FILTER (EVENT("INSERT"));
And that runs some spel code which grabs the key info from the change, logs it and then inserts an event into the Change ticket. The event launches an Execute PAM Macro. The Macro runs a PAM process that is designed to read the survey, gather the Risk Ranges, Questions, Answers, Workflow Tasks and Properties and then takes certain actions based on the answers per requirements that I was given. Seems to be working pretty well in Dev so far.
