Data Flow Runs landing page fails to load
SA-47787
Summary
Error on opening the Data Flow Runs landing page.
Error Messages
The Flow Action pre-processing activity pzInitializeLP failed: Problem invoking function: pega_rules_utilities.callActivity--(ClipboardPage,String,ParameterPage), Comparison method violates its general contract!
Steps to Reproduce
- Create an activity to execute the data flow programmatically.
- Include 25 to 30 Data Flow Run IDs created in the Data Flow landing page.
- Configure a Data Flow Run ID created, as DF-4z.
Root Cause
When the 'Data Flow runs' landing page contained a number of Data Flow Run objects (about 20) and not all the runs had standard Run IDs (standard Run ID matches the pattern 'DF-XXX', 'DF-TEST-XXX', where XXX is a number), then the Data Flow runs landing page failed to load with sorting error.
Resolution
Apply HFix-39077.
