问题 I have a variable inside an application scoped bean. A user can trigger an update of this variable through a method call. Now the problem is that the user doesn't get an updated view of this variable after refreshing the jsf page. If have tested if the variable is updated properly and it is, so the method for updating is working correctly. Are variables inside an application scoped bean declared as final or what is the problem here? 回答1: That can happen if you used the wrong combination of

问题 I have this selectable PrimeFaces Tree with an Ajax listener on selection in my index.xhtml: <p:tree value="#{seccionesArbolView.root}" var="node" selectionMode="single" > <p:treeNode> <h:outputText value="#{node.nombre}" /> </p:treeNode> <p:ajax event="select" listener="#{seccionesArbolView.onNodeSelect}"></p:ajax> </p:tree> The listener method is on a session scoped named bean, and should redirect to another page (grupal.xhtml) with some GET parameters.

问题 I have a simple example of p:tree . <p:tree id="tree" styleClass="treeskin" value="#{TreeViewController.root}" var="node" dynamic="true" animate="true" selectionMode="single" selection="#{TreeViewController.selectedNode}" highlight="true"> <p:ajax event="select" listener="#{TreeViewController.onNodeSelect}" update=":treeform:outputComponent"/> <p:ajax event="expand" listener="#{TreeViewController.onNodeExpand}" /> <p:ajax event="collapse" listener="#{TreeViewController.onNodeCollapse}" /> <p

问题 As per the primefaces document the selection should be a array. In the below code bean.selectedUsers is defined as "HasUsersVO[] selectedUsers" but the value of datatable is List.

问题 I've followed this tutorial for implementing a marquee-tag in JSF 2.1 and succeeded partly. As this tag does NOT support dynamic data, e.g. #{bean.var} as a value, I've decided to do it dirty inside the component. However, after reloading my page, the value disappears. The tag is still there, but the content is gone. Could you show me how to implement is correctly, that I can use my dynamic value inside the value-attribute ? Or would you point me into the right direction which code is causing

问题 I'm referring to an answer here: Why can't I get ViewScope to work? Throws errors every time I didn't read view scope properly. You can only have one form per page. The bean is created multiple times if you have more than one form. I can't confirm this. Can anybody please deny it? (if the quote above does apply, where's the appropriate reference for this?) Thanks 回答1: That is nonsense. OP's problem is caused by something else which has been reported as issue 2215. 来源： https://stackoverflow

问题 Hi guys I'd like to ask if there is a way to customize the terminal component in primefaces 2.2.1 ? Id like to change the default prompt which is "prime $" into something else.
