The object model is indeed not made available in the flow script. You 
can get it from the Avalon context though (code from
Unfortuntely, this one is neither available by default. I remember Ard 
posted a solution a while ago to retrieve the Avalon context in a 
hackish way.

Another workaround is to create a map in your flowscript with the 
necessary data.

To dev: How is this supposed to be handled? Should access to object 
model be granted? What does the unified object model change about this?

That's what you should do. Otherwise life cycle methods like recycle() 
don't get called. It depends on your component if it results in an 
actual problem. Of course the using code should not be aware of the 
component's implementation details - and that's why it should always 
release the component.
