Instant JChem script errors

I execute in datatree the example script create new grid (http://www.chemaxon.com/instantjchem/ijc_latest/docs/developer/scripts/create_new_grid_model.html) and I have the following error:

groovy.lang.MissingPropertyException: No such property: dataTree for class: SchemaScript

 at New Script 2(<self>:4)

 

I need help.

It looks that the script is not part of your data tree. It's in the schema script folder and will not work from there.

Please see the difference in screenshot. There are different levels where you can have the scripts.
