Can you help us understand what seems to be the issue?

Commenting out the Page-Copy method call makes the activity run successfully, but trying to access from clipboard the page on which Apply-Parse-XML was called results in the following error:

Thread Lock Message

InvalidParameter cannot be null aValue com.pega.pegarules.data.internal.clipboard.ClipboardPropertyImpl.add()

with no additional error in the logs.

We're using Pega 7.1.8 

Any help would be appreciated.

Hi all,

Although the problem description doesn't seem similar, I tried the solution proposed for this problem: https://collaborate.pega.com/question/apply-parse-xml-method-not-working and it worked.

In our case, the Apply-Parse-XML method doesn't fail and produces the expected result, but leaves the page in an inconsistent state, which causes errors when trying to execute the Page-Copy method (or when trying to review the page in Clipboard).

The solution was to create the following DSS:

Purpose : SwitchToOldAssembler Owning Ruleset : Pega-IntegrationEngine Value : true

@MarcLasserre_GCS  I have verified the page contents, there is no issue. If instead of Page-Copy we create the target page and copy the properties individually using Property-Set, we have no error either, and the page content is exactly what is expected.
