  1. After OA upgrade to 7.3 version APS-related screens are hanging in endless loading or appear blank.

  2. Browser console contains the following messages during opening of screens:

    Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://undefined') does not match the recipient window's origin ('').

    where - is a name of customer's brand.


Fresh version of OA cannot handle the cache of brands that remained on UI nodes since previous version of product.

Additionally, the Feature Request PFR-1370 Clear brand's cache on brand node has been submitted to the Development Team to perform this procedure in scope of Post-Upgrade actions.


This issue can be fixed by clearing brand's cache on brand node with restart of pau service afterwards:

# rm -rf /var/cache/brands/*
# /etc/init.d/pau restart
