Hi RekhaB83,

I have faced similar issue when my section was reffering to the rules which are not available.

This issue generally happens when we Save As a section from one class to the other and do not check for other rules like when rules it is referring or any other subsections.

 

Thank you.

Rakesh.

I have not saved any new section in this case. And issue is intermittent as it's not occurring for all the cases. I just noticed that .pxFlow(StartFlow).pyFlowParameters has some issue. When I tried Actions > show XML from Clipboard on that page ,it gives me the same error. I compared page values with the cases which are good. This page had a property pyXMLRootNode whereas it's missing in error cases.
