JSF with Prettyfaces navigation -

-

I am using JSF 2.2 with PrettyFaces 3.3.3 in my Entreprise application.

I am thinking that the way I handle navigation is correct (AdminCompaniesController.java): 

  @ManagedBean (name = "companiesBean") @ViewScoped @URLMappings (mappings = {@URLMapping (id = "admin-companies-view", pattern = "/ admin / company / view / # {id}", viewId = "/ admin / companyView.jsf"), @URLMapping ( Id = "admin-companies-view", pattern = "/ admin / company / edit / # {id}", viewId = "/ admin / companyEdit.jsf"), @URLMapping (ID = "admin-companies-add ", Pattern =" / admin / company / add ", viewId =" /admin/companyAdd.jsf "), @URLMapping (id =" admin-companies " A. List "pattern =" / admin / companies ", viewId =" /admin/companies.jsf ")}) public class administrator Consulting controller executes Siriyliz qualified {@EJB private Kanpanisewa Kanpanisewa; Private collection & lt; Company & gt; Companies = new arreelist & lt; & Gt; (); Private company company; @PostConstruct Public Zero init () {string viewId = NavigationUtils.getViewId (); Switch (view ID) {case ("admin-companies-list"): companies = company services. break; Cases ("admin-companies-add"): company = new company (); break; Case ("admin-companies-view"): case ("admin-companies-edit"): Long ID = NavigationTotal .getParameter ("id", long.class); Company = companyService.getCompanyById (ID); break; }}

I am using PrettyFaces parameter from annotation:

NavigationTotal: .getViewId () equals PrettyContext .getCurrentInstance () .getCurrentMapping (). GetId ()

and from url:

NavigationTotal .getParameter ("id", long.class) FacesContext.getCurrentInstance () Is equivalent to. GetExternalContext (). GetRequestParameterMap (). Get ("id")

Is this the correct way to manage CRUD operations? My unit "company"? I've read about the OCPSoft documentation () about @URLQuery parameter and @RockTracker , but I'm not sure how to implement them instead of my switch / case solution. As the @chalk says:

Think about using the bean. Every mapping that basically means that you will end up with a square of each page. IMHO makes it completely understandable. Your current approach seems to be that you keep God class Are there.

The above suggestion is good practice, and stops the requirement of a case statement, because each @URLMapping - the annotated bean has its own clear @Razaon or @PostConstruct will be the method. Additionally, you can use direct injection to pass parameters values ​​to those beans without using the request parameter:

@URLMapping (id = "Admin-companies-view", pattern = "/ admin / company / view / # {id: pageBean.id}", ViewId = "/admin/companyView.jsf")

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
