问题 Lets say I have a managed bean called A that is @RequestScoped Let's say A has a reference to another managed bean B and B is declared to be @SessionScoped .

问题 I am trying to update the page size of a PrimeFaces datatable dynamically, after the datatable is displayed on the page but I can't seem to be able to do that. I am using a lazy loaded datatable if that matters... putting an EL expression in the rows attribute and doing a table refresh does not work and causes the paginator to return no data. Any ideas if this is a bug and how to fix it? Thanks 回答1: You need not refresh or update the datatable. Use EL expression in rowsPerPageTemplate

问题 I am having a problem with not closing a PrimeFaces dialog. The input field 'username' is required: <p:outputLabel for="username" value="Username: "/> <p:inputText id="username" value="#{employeeController.employee.username}" required="true"/> I used the following code to prevent the dialog from closing if the field is empty: <p:commandButton value="Save" action="{employeeController.doSaveEmployee()}" oncomplete="if (args && !args.validationFailed) PF('employeeAddDialog').hide()" update="

I tried multiple ways to establish this, but none did work so far. Here is one approach: xhtml: the idea is, to pass the element through a commandLink action attribute (which works fine for e.g. data tables): <fl:composition template="/WEB-INF/template.xhtml" xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:fl=
