blob lblb_Json
Long ll_RootObject
JsonGenerator lnv_JsonGenerator
lnv_JsonGenerator = Create JsonGenerator
// Create an object root item
ll_RootObject = lnv_JsonGenerator.CreateJsonObject()
// Add a value child item
lnv_JsonGenerator.AddItemString(ll_RootObject, "string", "string")
lnv_JsonGenerator.AddItemNumber(ll_RootObject, "long", 100)
lnv_JsonGenerator.AddItemDateTime(ll_RootObject, "datetime", datetime("2017-09-21 12:00:00"))

datastore lds_employee
datawindowchild ldwc_active
JsonPackage lnv_package
lnv_package = create JsonPackage
...//Initialize data for lds_employee, ldwc_active
// package the data
lnv_package.SetValue("d_department", dw_department, false)
lnv_package.SetValue("d_employee", lds_employee)
lnv_package.SetValue("dddw_active", ldwc_active, false)
