Page flow artifact

Page flows are a work in progress and are subject to change, this page is more here as a reference, please check back in future when page flows will be properly supported. |
A page flow implements a work flow for web pages. Typically page flows are used for the implementation of well defined processes in a web front-end.
Page flows define a work flow diagram that contains views, models, actions, command classes and validators.
Coding conventions for page flows
Page flow names should end with "PageFlow". This first part of the class name defines the page flow id. The page flow definition must be defined in the property "flow" of type grails.pageflow.Flow.
class OrderFormPageFlow {
@Property OrderService orderService
@Property Flow flow = new PageFlowBuilder().flow {
showOrders(view:'orderList',model:[orders:{ orderService.loadOrders() }]) {
detail('loadDetailBind')
}
loadOrderDetailBind(action:[class:OrderDetail.class,name:'orderDetail']) {
success('loadDetail')
}
loadOrderDetail(
action:{
ctx ->
ctx.requestScope['order'] = orderService.findOrder(ctx.requestScope['orderDetail'].id)
return 'success'
}) {
success('showOrderDetail')
}
showOrderDetail(view:'orderDetail') {
list('showOrders')
}
}
}
