Interesting, when you’re using component binding on a view scoped bean, the view scope breaks. I am not sure if that is a bug in JSF2, I would have to read the entire JSF2 specification first. As far now your best bet is to drop the component binding for now and pass the selected item … Read more
Changing my initial answer – there is no meaningful difference between the two. The tutorial says that backing beans are later declared as managed beans. So, to summarize: a backing bean is the class out of context a managed bean is the backing bean whenever it is declared to be used with the JSF managed … Read more
Lets start by removing the outer h:form (form that wraps the <p:wizard> ) cause you got a nested forms here (which is bad)
Create a custom service layer specific runtime exception which is annotated with @ApplicationException with rollback=true. @ApplicationException(rollback=true) public abstract class ServiceException extends RuntimeException {} Create some concrete subclasses for general business exceptions, such as constraint violation, required entity, and of course optimistic lock. public class DuplicateEntityException extends ServiceException {} public class EntityNotFoundException extends ServiceException {} public … Read more
CDI 1.1 introduced an AlterableContext interface with a destroy(Bean<T>) method. Get the session context via beanManager.getContext(SessionScoped.class), downcast to AlterableContext and then invoke destroy() with the appropriate bean type.
The #{component} is an implicit EL variable referring the current UIComponent in EL scope (see also implicit EL objects). You can usually only refer it in component’s HTML attribute or in template text children. E.g. in case of <h:inputText> it will reference an instance of UIInput class which has among others an isValid() method. <h:inputText … Read more
Is it possible to bind a List of HashMaps to the jsf component h:dataTable? That’s only possible if you generate the necessary <h:column> tags with a view build time tag such as JSTL <c:forEach>. Here’s a concrete kickoff example, assuming that your environment supports EL 2.2: <h:dataTable value=”#{bean.listOfMaps}” var=”map”> <c:forEach items=”#{bean.listOfMaps[0].keySet().toArray()}” var=”key”> <h:column> #{map[key]} </h:column> … Read more
The transition from the XHTML source code to the generated HTML output is a two-step process. First, during view build time, the XHTML source code is parsed and turned in a tree of Java UIComponent instances representing the JSF UI component tree, as available by FacesContext#getViewRoot(). Then, during view render time, the JSF UI component … Read more
The default decimal separator depends on the locale used. You can set it in 2 ways: On a per-view basis by the locale attribute of the <f:view> tag: <f:view locale=”#{bean.locale}”> On a per-converter basis by the locale attribute of the <f:convertNumber> tag: <f:convertNumber locale=”#{bean.locale}” /> It’s unclear what locale you’re targeting, but the use of … Read more
All you need to do is basically indeed just adding an empty object to the datamodel behind the value attribute of h:dataTable. But the same empty row needs to be preserved in the subsequent request as well. If the backing bean is request scoped, then the datamodel get reloaded without the empty row. This all … Read more
