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="

问题 i need to access the data object of an org.primefaces.model.diagram.Element in a managedBean on click of this very element. I am using primefaces 5.2. 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=

问题 I am struggling with a primefaces calendar problem on a webpage rendered on a mobile device (tablet). It seems that the css values calculated by primefaces to show the popup calendar are not recalculated on window rotation (you need to click on it again to recalculate). Here is an example: I have my webpage displayed in portrait mode. I clicked the calendar icon and the position of the popup is good: (notice the css with left: 719.406px, calculated by primefaces). Everything OK so far. Now I
