问题 I'm trying to develop a custom component that will need to call a method from the backingbean to get some data from the bb (this will be called in the decode phase after a certain Ajax call) with one parameter (it will come in the ajax call). The problem I'm having is that I define the attribute as a MethodExpression (in the taglibrary and the component), I get the Ajax post, decode the parameter and when I try to get the Method binding from the component I get the following error: javax.el

问题 Apologies for not abstracting this problem in a dedicated test case, I hope the example from a real project is simple enough to describe the problem. I have a JavaEE/JPA2/JSF web application where every @Entity Element (or subclass) has a templated view.xhtml page, and a standard link generator composite component util:view_link.xhtml, invoked as GET with database ID as parameter. A portion (only) of each view page represents an expert system summary; that portion can be abstracted as a

问题 I have a form with a variable number of input elements, like this: <ui:repeat var="_lang" value="#{myBean.languages}"> <h:inputTextarea value="${_lang.title}" id="theTitle" /> <h:messages for="theTitle"/> </ui:repeat> When a certain method in the backing bean is triggered, I want to add a message to, say, the second iteration of the ui:repeat , but not the other ones. I've seen different variations of this question around here, and all problems appear to be due to the ui:repeat 's iterations

问题 I'm using an p:selectOneRadio with p:ajax and the value of another component ( p:inputText ), not binding its value in my bean. If I use p:selectBooleanCheckbox instead the behavior is exactly what I need, update the bean before calling the method in ajax. Is this a bug in p:selectOneRadio or is this its default behavior? I'm using JSF2 , PrimeFaces 4 The xhtml code: <p:selectOneRadio id="enumId" value="#{xyzController.entity.enumValor}" disabled="#{disabled}" required="true" plain="true"> <f
