JSF cross field validation via postValidate without looking up components by name in backing bean

由 你。 提交于 2019-12-01 11:13:09
I'm building a login form composite component. The page that uses it will pass an event handler that will validate the username and password. Usually (not using composite components) when we perform cross field validation via postValidate , the event handler has to lookup the fields' components by name. It would be preferable for the validator not to do this, because these are inner details of the component that should be abstracted. Any idea how I might get the converted values of the username and password fields in a postValidate handler without knowing the inner details of the composite

JSF define custom namespace for component declaration

由 两盒软妹~` 提交于 2019-12-01 10:09:43
问题 when you use a component from extarnal libraries (or custom component) in JSF page you add the xmlns declaration, for example: xmlns:util="http://java.sun.com/jsf/composite/component/util I would like to know what I have to do to use a private address in the Namaspace like this below: xmlns:p=" http://primefaces.prime.com.tr /ui" It is something related to packages? Or it depends from the name of the .JAR that contains the components? Thank you! 回答1: For Facelets this is definied in .taglib

问题 Is it possible to have a JSF component that has ui:repeat and inside the repeat call the same component?

Composite component required attribute throws exception in Mojarra 2.0.3

由 三世轮回 提交于 2019-12-01 07:36:50
I've been playing around with JSF 2.0 composite components but I'm a bit confused as to what the require attribute in the composite:attribute tag is meant to do. The documentation says that the required attribute is true if the page author must supply a value for this attribute. I've interpreted that as meaning that a value must be supplied for all composite:attributes that have required=true . I also assumed that an empty string is a valid value. And this is how it worked in Mojarra 2.0.2. Using this simple managed bean: @ManagedBean(name = "simpleMB") @ViewScoped public class

Specifying different error messages for different composite components

由 霸气de小男生 提交于 2019-12-01 07:24:48
问题 Is there a way to have REQUIRED messages for different kinds of composite components? I'd like to be able to say something like the following in a message bundle javax.faces.component.UIInput.REQUIRED=Please enter a value for {0} com.anon.sandbox.jsf.component.NameField.REQUIRED=ENTER A {} OR DIE com.anon.sandbox.jsf.component.EmailField.REQUIRED=You forgot to enter a {0} address I could do this by implementing custom validators for each kind of input field, but given that the only behaviour
