I cant visit the gsp page in my moudle

When I vist the Chart.page I met a bug UI Framework ErrorRoot Errorgroovy.lang.MissingPropertyException: No such pr - Pastebin.com

hello @zzy It looks like you have an undefined variable “refs” in our gsp page. please try giving it content or defining it from the controller classes

@zzy you are trying to point to some unknown property refs ,check your classes and make sure its some thing defined
