I tried to analyze your code, but it seems, its out of my scope.
The error message states
" SEVERE: >>org.zkoss.zel.PropertyNotFoundException: Property '0' not found on type demo.grid.hierarchy.Customer "
I guess, the property '0' is not set in customer class in your code, since you are using it in your mainPage, try replacing this 0 with some property in the Customer class.
Not sure this will helps or not.
