OK I give up for now - just tire to look for a solution all the day !!!!
Even your extension, MattEsch, doesn't work in runtime (it returns nothing, etc..., even after being declared into the extension and runtimeDev js files) - I'm wondering if this EDIF solution does really work with the HTML5 runtime.
I hope Francois or others will be able to give me some help because I'm actually getting upset with this sdk.
