问题 I want to update a button in the header facet of a primefaces datatable and it does not work. I copied the button outside the datatable everything works fine. The update should happen when the filter event of the datatable gets fired. I explicitly update the datatable, the outside- and the inside-button. The intention is to display a button with an icon when no filter is set and another icon when a filter is used. In this example I simplyfied the use case: when no filter is used there is a

问题 I want to restrict p:inputMask to numbers only , and I tried the proposed solutions from: How to restrict an input to numbers only with PrimeFaces inputMask element But none of them worked. I tried these two ways: <p:inputMask id="userNo" maxlength="2" mask="9?9999" /> and <p:inputMask id="userNo" maxlength="2" > <pe:keyFilter regEx="/[0-9_]/i"/> </p:inputMask> 回答1: I think that approach is right but I noticed that you don't put value attribute on inputMask . Do you try to put it on? Edit:

问题 Good Day. I've created a PrimeFaces 5 project (JSF 2.2) which makes use of Spring Security 4. I'm attempting to make use of p:dataTable control with single selection enabled, which through an ajax call, updates a p:pickList control. The problem is related with Spring Security. If I deactivate the security of the page where my page controls are located (admin.faces), the ajax behavior works fine. But if I activate security, I get 403 status codes and the pickList doesn't get updated. I must

问题 I have been trying to call a custom listener when the cancel button is clicked in the primefaces rowEditor component. But I am not able to find the correct attribute to do this. The problem with the cancel button is that it works fine when the row is already present in the dataTable, if I try to add a new row dynamically to the dataTable and click on the cancel button [ if I think that it is not required ], the empty row is shown in the dataTable, when the empty row should be deleted. Would

问题 I'd like to keep a part of my menu static in markup, and have another part dynamically generated in Java. <p:menubar> <p:menuitem value="static stuff"/> <p:submenu label="dynamic stuff" model="#{bean.dynamicMenu}"/> <!-- more static stuff --> </p:menubar> This shows only the static items and never calls my getDynamicMenu method cause p:submenu does not take a model attribute. I tried using ui:include within the menu structure to move the markup in an extra file and include that in different
