What's the cause of "Failed to preload gadget..." for Sharebox gadgets in IBM Connections

Question

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?

Answer 1

OK, shamefully, it looks like I missed out swapping the security attribute whitelistEnabled="true" to whitelistEnabled="false" in:

/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/connectionswwCell01/LotusConnections-config/opensocial-config.xml

Here:

<security whitelistEnabled="false" featureAdminEnabled="true">

Of course, in a production system, you'll have to checkout the opensocial config using wsadmin.sh, edit, checkin & restart.
