When or transition steps preconditions are not visible



After upgrading from PRPC 6.2 SP1 to Pega 7.1.6 , it is observed that precondition of when and transitions steps are not visible.

Error Messages

Not Applicable.

Steps to Reproduce

1. Create an Activity.
2. Add the precondition step. Observe that the precondition box does not appear.

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules.

When verified the pzPreCondition section which has the preconditions grid. It has Grid visibility condition set to .pyStepsPreCondition=='-1'
the grid was visible after the  removing this condition.
For the same activity it was observed that .pyStepsPreCondition value for pySteps (for example, RH_1.pySteps(9)) in the clipboard it is set to true.​
Grid visibility condition set to .pyStepsPreCondition=='true' (instead of .pyStepsPreCondition=='-1' ) the precondition steps were visible. 


This issue is resolved by HFix-22052.
