I try with the script (https://docs.chemaxon.com/display/instantjchem/Create+New+Grid) to generate a new grid view but i get the followin output:
groovy.lang.MissingMethodException: No signature of method: DataTreeScript.newFieldReference() is applicable for argument types: (java.lang.String) values: [Structure]
at Nueva grid(createTableWidget:21)
at Nueva grid(<self>:8)
Did you somehow modify the script? It works fine for me. Maybe there is badly copied the quotation mark: " which specify that what is inside is the String type. For some reason it does not seem to be a string.
Please try to copy-paste the script from attached file. Does it work now? Was the script correctly copied from the web-page or were there any unexpected troubles?
