How to postmessage using Javascript to third party application from pega case
Hi,
we are trying to postmessage using javascript to third party application (parent window) which opened pega (child window).
when we are triggering postmessage from portal, it is working fine. But when we are triggering the same thing inside a case section it is throwing error
"Filed to execute 'postMessage' on 'DOMWindow' : the target origin provided('----') does not match the recipient window's origin ('---')"
I think pega is not recognizing the origin when we open any frame inside pega after loading the portal. any solution to solve this will be very helpfull.

Hi All,
I got the issue, script is not able to identify window.opener from inner frames of Pega, so used window.parent.opener. this worked like a charm for Chrome. But still not working for IE.
IE is returning undefined for window.parent.opener or window.opener.

Hi
Can you share the javascript that you are using. The problem may be with the links that you are using have different protocols like http and https. Can you try this solution in https://stackoverflow.com/a/27574013

Hi, Thanks for the reply. both links are using HTTPS and as i mentioned this working fine from portall level, but not from any other page within the portal like (case or popup)

I think you are violating browser's same-origin policy. Check CORS specification for more details. If Pega and the other application are in different domains, you need to enable CORS via access control policy headers.

Hi , Thanks for the reply. if that is the case it should not work from portal level it self. but postmessage to different origin is working successfully from portal. But not from any other screens inside portal.
where can i enable CORS via access control policy headers? Pega DSS CORS allowedorigins in my application is '*', which is accept request from all origins. further in my case i am not listening to request, but posting message to other application.
