Hi,
Using "this.somExpression" will return a string of the full object path;
xfa[0].form[0].topmostSubform[0].Page2[0].Competitions_CB[0].Checkbox[0]
You can also use "xfa.context.somExpression" to return the same thing, using xfa.context is handy when the code is in a script object and called from many object events.
Also, "parent.name" would return the "Competitions_CB" part, so parent.somExpression would return
xfa[0].form[0].topmostSubform[0].Page2[0].Competitions_CB[0]
