>From my recent experience, I think you should :
- define a default value for your properties in your content
interface :
myFloatProperty1 = Float (..., default=0.0)
myFloatProperty2 = Float (..., default=0.0)
- define the "set_before_add" value in your browser package
"configure.zcml"
<addform
schema=".interfaces.IMyInterface"
set_before_add="myFloatProperty1 myFloatProperty2"
...
/>
I think that this should do the job you're looking for.
