I've followed the procedure documented at "Adding new ways to share content"
...but keep getting an error:
Failed to preload gadget http://....
Detailed error: 400 Gadget is not trusted to render in this container. cre.iruntime:cre.iwidget.event:cre.wire:cre.iwidget:cre.iwidget.itemset:cre….ibm.connections.ee:ibm.connections.ee:container.nongadget:open-views.js:4
sharebox error http://i7.minus.com/ibiLz4SSWA5EL8.png
This looks like some sort of trust problem with external servers, but my other gadgets (embedded experience & home page gadgets) on the same external host are all working fine.
What have I missed out in the configuration?
