问题 I want to create validator for custom component where I want to pass few attributes. This is how code looks like (it's not original code but is implemented in the same way): Custom component (customComponent.xhtml) <h:body> <composite:interface componentType="compositeComponent"> <composite:attribute name="name" required="true" /> <composite:attribute name="value" required="true" /> <composite:attribute name="values" required="true" /> <composite:editableValueHolder name="validator" targets="

问题 <h:selectManyListbox value="#{bean.selectedColor}"> <f:selectItems value="#{bean.colors}" var="u" itemLabel="#{u.code}" itemValue="#{u.description}" itemDisabled="true"/> </h:selectManyListbox> I set itemDisabled to true in f:selectItems but it is still enabled on the screen. Please let me know if I am missing anything. 回答1: This generates a HTML <option disabled="true"> element. The specified behaviour is that the item is unselectable, not that the item is hidden. You seem to be expecting

问题 I want to create a way to update references to css files in jsf in an automated way (through ant, etc.) what is the common practice for this? are there any automated tools available already? Basically I want to be able to deploy my war file and make sure that any changes the modified css files are downloaded by clients without them having to clear their cache.

问题 I have the following dialog with a dataTable.

问题 I have a file upload applet in my jsf page. This applet expects an adress where it can send it's POST request. (I can't edit this post request to add more fields or something). The post method of my servlet then stores the file. This job can't be done by a managed bean because the servlet has to be annotated with @MultiPartConfig and I can't add this annotation to the jsf managed bean. In order to force the upload applet to use the same session I added an URL attribute named jsessionId to the

问题 I have a ViewScoped Managed Bean. In my .xhtml page I want to set bean's attribute's value and use it in methods in the same bean. I managed to set the value from jsf page, but when i want to use it in some method the value of an attribute is not the value i have set before. Description (xhtml): In this form there is a command link which sets the value of an attribute. And it is working fine. Also, as command link is clicked, second form is being showed. <h:form> <h:commandLink value="Set" >

问题 I have a servlet filter to force user authentication. It checks for the existence of a non-null object in the HttpSession. For some reason that I cannot figure out, the session contains an object with the correct name, but HttpSession.getAttribute is returning as null. Here is the process that it goes through. from the login page, it calls an action which contains the following user validation code. At this point I am 100 percent sure the object "login" is not null. if (passWordIsValid) {

问题 I'm trying to integrate Spring 3 into a JSF 2 project. I registered the SpringBeanFacesELResolver in the faces-config.xml and I added two listeners to the web.xml: <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener> Most views and backing-beans are just working, but unfortunately, the javax.faces.event

问题 I am new to the JSF. Can anybody please explain me why binding attribute is used in the code below: <h:form id="epox" binding="#{rxManufacturerEditor.form}" /> I am a bit confused with value and binding attributes, however I am not getting why we mention binding attribute with form tag. 回答1: The only reason to use binding to a backing bean's UIComponent instance that I know of is the ability to manipulate that component programmatically within an action/actionlistener method, or ajax listener
