java.lang.RuntimeException: Component stack mismatch
Our application has been upgraded to 7.3.1 an year ago and since then, on a random basis, users are getting Harness failure error. When verified in logs, we saw a RunTimeException which says,
java.lang.RuntimeException: Component stack mismatch {"section":"XXXX","ver":"1","objClass":"Rule-HTML-Section","class":"XX-YY-ZZ","RO":"false","sectionBaseRef":"","expandRL":"","UID":"SID1548168960812","outerGadget":"GID_1548168960803","pyName":"pxSection","pyTemplates":[{"NTId":"1548168960810000","NTRef":"377a281255308411b9d9c369082c39b9_2","pyName":"pxNonTemplate"}]}!!!!===={"containerType":"CENTER","isClientWhen":false,"isVisibilityOption":"","pyName":"pxHarnessContainer","pyTemplates":[{"whenId":"3446558839592bbdd282724cb6956d2e_4","pyName":"pxVisible","pyTemplates":[{"NTId":"1548168960776000","NTRef":"8bb8687bb6525f4960bf3d5bee28fae1_1","pyName":"pxNonTemplate"}]},{"pxReferencedId":"3446558839592bbdd282724cb6956d2e_5","pyName":"pxSection"}]}
This being random, we are not able to pinpoint the issue. Also, it is occurring in several places of the application but the common part is that, the sections have a repeating list in the form of a Table or row repeat etc.,
So, I wanted to check here before raising an SR. Anyone who has faced this issue and found a solution, please suggest.
Thanks in advance!!

I have gone through this conversation before raising this question. That speaks about 8.1.3 patch for which we do not have plans for.

Can you confirm if you are getting harness related(eg: NullpointerException) errors related to "DisplayharnessWithClass". Also, please share with us the complete logs.

Hi ,Have you tried revalidating and saving ? Sometimes issues like these gets resolved by revalidating those sections .
or Do a private edit and save that and check if the exception is still appearing .

The issue was with failed when rule in the section. There was a RuntimeException around the same time which had the rootcause pointed at.
