Syllabus Tool Cross-Origin iframe issue

[ThirumalReddyN]

Hi All,
with this connector portlet we have an issue,
When we are trying to add Item in syllabus tool, Add Item popup is not opening.
If i see the logs in browser console, i got following error message,

syllabus.js:577 Uncaught DOMException: Blocked a frame with origin "http://myDomain.com" from accessing a cross-origin frame.
at showConfirmAdd (http://myDomain.com/portal/tool/f927fc8a-f2cf-41e6-a78c-c3189b3fd0e2/js/syllabus.js:577:27)

at HTMLAnchorElement.onclick (http://myDomain.com/portal/tool/f927fc8a-f2cf-41e6-a78c-c3189b3fd0e2/main:138:71)

anybody have an idea about it..?

Please give me your suggestions.

Thanks,
Thirumal

What portal is being used to run the sakai-connector-portlet?
