We have a MapGuide setup where the application is hosted at: https://domain *1*.com And the map is served from: https://domain*2*.com
When embedding the MapGuide Viewer (reactviewer) in an <iframe> on my application domain1, We get the following error in the browser console: SecurityError: Failed to set a named property 'Fusion' on 'Window': Blocked a frame with origin "https://wms.geomind.co.il"; from accessing a cross-origin frame at t.componentDidMount (viewer-shim.tsx:1169:14) *p.s - It works fine under AjaxViewer* I understand this is a browser cross-origin restriction. In my case, I cannot simply merge the domains into one, and I need a solution to allow the application to communicate with the viewer without getting blocked. *My questions:* 1. Is there a recommended way in MapGuide to handle cross-domain embedding between the application and the viewer? 2. Does mgreact have a built-in API to handle postMessage communication between iframe and parent, or do I need to implement a custom widget? 3. Is there any server-side configuration in MapGuide or Fusion that can bypass the window.top.Fusion assignment in viewer-shim.tsx for cross-origin cases? 4. If I have to modify viewer-shim.tsx, what is the best practice to keep it compatible with future MapGuide updates?
