Property Optimization wizard fails



Property optimization for a pagelist property fails. Additionally, the column population does not complete and ends with the status 'Completed with errors'.

Error Messages

The property .cata was of mode String while was expecting Page mode

InvalidReference .Cata_Detail.user_id list property 'Cata_Detail' must have an index

Steps to Reproduce

Run property optimization wizard for a pagelist property.

Root Cause

An issue in the custom application code or rules.

The property optimization request to the server is manipulated using a fiddler. If the request is to expose the user_id property of the Cata_Detail pagelist, then the target property in the request is manipulated to cata.user_id. This must have been Cata_Detail.user_id(). Hence the error, 'The property .cata was of mode String while was expecting Page mode', occurred.

In the second attempt, the target property is '.Cata_Detail.user_id' which is incorrect. Hence the errors in logs, 'InvalidReference .Cata_Detail.user_id list property 'Cata_Detail' must have an index.' 

In the final attempt, though the property is exposed correctly, the column population failed because of the first two failure attempts.


Perform the following local-change:
  1. Save the Work- class instances with the pagelist property which must populate the columns. 
  2. Run the column population utility using ‘nonpega’PRPCUtils,
  3. Configure the PRPCUtils properties file. This utility can also rebuild Index- instances defined by Declare Index rules. In the properties file, ‘expose.reindex’ must be set to true and ‘expose.reindexType’ can be set to 'nonpega'.
