Steps to Reproduce
1) Have a section with a UI control, e.g. a drop down. Set an onChange to trigger a refresh section. Set an activity that has a parameter. Pass a value to that parameter.
2) Run and make sure the section is working ok with the parameter being passed.
3) Edit the section and remove the activity.
4) Run the section again and trigger the refresh section.
Root Cause
The root cause of this problem is a defect in Pegasystems’ code/rules. When the activity is cleared, the section rule is suppose to remove the parameter. But this was left out.
Resolution
This issue is scheduled to be resolved in Maintenance Level (ML) release 7.1.8 (BUG-196408).
