Steps to Reproduce

2. Open any existing rule in the application.

3. Click on Save-as.

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules. The application is failing to validate its ruleset dependency chain.  This happens because the rule utility function that verifies the dependency chain is looking for a property named 'pyRequiresRuleSetVersionPageList' (mode: page list) (added in 7.1) for the RSV's immediate dependencies.  The dependency check starts at say XXX:01-01-01, goes to check its dependency of YYY:01-01-01 and stops there because it doesn't contain the aforementioned property.  

YYY:01-01-01 Being a Previous 5.X application. It does contain the 'pyRequiresRuleSetVersion' property (containing the same information with a mode of value list).  
The nature of this bug is that the dependency check is not backward compatible with old Rule-RuleSet-Version instances that do not contain the newer  'pyRequiresRuleSetVersionPageList' property.


pzFilterAvailableRuleSetsForRecord is calling  ---> pzFilterAvailableRuleSetVersionsForRecord (which in turn calling a when rule)--> pxAllowsRecordInRuleSet  (which is getting the resultset from a function) --> pxAllowsRecordInRuleSet.
As all the rules are final user commented the steps 12,13 in pzFilterAvailableRuleSetsForRecord which actually perform the page remove of the rulesets by doing a private checkout of the rule. The same issue is fixed in PRPC 7.1.7.
