Simone Gianni commented on COCOON-1804:
---------------------------------------

I'm trying to solve this issue. The way I'm acting is the following :

- Implementing a lightweight FOM_SimpleCocoon as a javascript host object giving access to session, request etc..
- Passing the object model if present in JavascriptHelper.getRootScope (called if a script flow scope is not present)
- If there is an object model instantiate the FOM_SimpleCocoon object in a new scope and use that.

Everything is done, but i keep receiving a 

org.mozilla.javascript.PropertyException:
Constructor for "FOM_SimpleCocoon" not found.

I tried everything, from not declaring a costructor at all, declaring expliticly an empty constructor, declaring a costructor with a parameter and passing that parameter in the ctx.newObject method, declaring a jsConstructor method, but still can't understand where the problem is.

Does anyone have an idea? I followed this tutorial http://www.mozilla.org/rhino/tutorial.html#AddingCounter step by step but it keeps on giving the exception.

Please help!
