Hi, I could use some help with getting my application compatible with Jira 8.12. I am facing issues with AUI 9. I have described my issue here, Creating a dialog using AP.require('dialog') in AUI 9.0.3 results in Cross Origin Request.
In a nutshell, opening a dialog (which contains an iframe) from a web panel (which also contains an iframe) results in a DOMException: Blocking a frame from accessing a cross-origin frame. The dialog is opened by posting a message from the iframe in the web panel to the parent window using parent.postMessage.
