Internal error while copying page
SummaryUser has implemented a series of multi-level embedded page properties which establish a reference to a data page.
The following error is generated from the RecalculateAndSave activity when populating a reference property and submitting the item.
Error Messages** internal error while copying page: The reference pyWorkPage.ProductLines is not valid. Reason: Cannot modify value of Reference Property without first linking it to another property using Property-Ref: code: <none> SQLState: <none> Message: <none>
** The reference pyWorkPage.ProductLines is not valid. Reason: Cannot modify value of Reference Property without first linking it to another property using Property-Ref
Steps to Reproduce
- Create a case type with property A that is configured to 'Refer to a data page'. There should be another embedded property that is configured to 'Refer to a data page'. Suppose B belongs to A.
- As work items proceed, populate property A and then B. Use the Property-Ref method to populate property B.
- Save the page.
Root CauseAn issue in the custom application code.
Property B under property A is defined as a reference property and established a reference to pyWorkPage.A.Lines(Health).
This corrupts the reference property behavior.
This piece of code works under Pega 6 but not in Pega 7 as the validations have been enhanced to capture this fault.
ResolutionPerform the following local-change:
Change the reference of property B from pyWorkPage.A.Lines(Health) to D_DataPage.Lines(Health).
