Error validating two inputText fields together

阅读更多关于 Error validating two inputText fields together

问题 I have a form with two input fields that have to be validated together . I used this BalusC tutorial as starting point. The requirement is a logical XOR: one of the fields must be filled but not both together . This works fine for all cases except this one: 1) Fill the first field and let the second blank 2) Move to the next page (values get saved) 3) Go back to the first page, delete first field and fill second field . Then I get the error message from my validator ("Do not fill both fields"

问题 I am building a custom UIComponent and adding elements (and other stock UIComponents) inside it. The component renders ok, however it cannot be found from the ViewRoot .

JSF beans and serializability issue

阅读更多关于 JSF beans and serializability issue

问题 I have problem with JSF beans using Spring managed services. I got an error telling, that spring bean used in JSF bean is not serializable. @ManagedProperty("#{customerService}") private CustomerService customerService; I can't make the service serializable, because it is using JdbcTemplate which itself isn't serializable. Moreover, serializing Spring beans which have application scope makes no sense at all, so I don't understand, why someone's code is attempting to serialize them. I have

阅读更多关于 JSF2.0 Passing Value objects between managed beans

问题 I've already written a small JSF2.0 app utilising Weblogic 10.3.4, PrimeFaces and JQuery. I'm now looking at converting our Main Web App to JSF2.0. This is currently uses Weblogic 8.1, Java 1.4 and JSP's. The question I have at the moment is what is best way to pass objects from one managed bean to another.

How to use both Navigation Rule and f:ajax

阅读更多关于 How to use both Navigation Rule and f:ajax

问题 Here's my scenario: I'd like to update a page via Ajax in some cases, in other cases, execute a navigation rule. My use case is a login form. I'd like them to receive an error message via ajax if their uname/password fails, but navigate to a new page if it succeeds. Has anyone done this using JSF2.0 f:ajax apis? I'm not really interested in solutions that go outside standard facelets, jsf2.0, etc. 回答1: It's not different from when doing it without ajax. Just return the next view ID as String

JSF2 and PrettyFaces… how does one get the original URL or the query string?

阅读更多关于 JSF2 and PrettyFaces… how does one get the original URL or the query string?

问题 PrettyFaces is a dead simple URL rewriting engine. All sorts of SEO is possible and it is really really easy . I have one small problem though :( Using pretty faces, I have this rewrite rule: <url-mapping id="blogEntry"> <pattern value="/blog/#{shortUrl}" /> <view-id value="/blogEntry.jsf" /> </url-mapping> So the URL bar looks like: http://host.com/blog/first-post And the rewrite rule maps the request internally to: http://host.com/blogEntry?shortUrl=first-post I'm implementing OpenID, which
