Steps to Reproduce

1) Create a workitem with the below structure: 

pyWorkPage 
--property1 
--property2 
--property3 
--MyPageList(a_class) 
---MyPageList(1) 
----ABC 
----CDE 
----DEF 
---MyPageList(2) 
----ABC 
----CDE 

The issue occurs when a workitem containing a Pagelist property where the number of properties within the list items are not identical. In the above example, MyPageList(2) is missing DEF property and when running BIX Extract the reported error will occur and the workitem will not be extracted. 

2) Create a BIXExtract rule with the same structure. It is important to have the single properties above the PageList properties in the Extract rule.

Root Cause

A defect in Pegasystems’ code or rules.
