问题 I've created an JSF Project from my Eclipse with JBoss Tools. Now I have the structure: MyProjectFolder ⌊ WebContent ⌊ WEB-INF | ⌊ lib | ⌊ faces-config.xml | ⌊ web.xml ⌊ META-INF ⌊ index.xhtml My web.xml maps the following extensions to the FacesServlet: /faces/* , *.jsf , *.faces When I now try to access /faces/index.xhtml , index.jsf and index.faces I get a 404 not found error.

问题 Hi Have this Wierd Issue in which I am using a Composite Component which I wrote and I get values from the previous use of the backing bean of the CC (the componentType bean) I don't know how to describe this better than just show the code. I'll try to be brief about it and cut the redundant parts: This is the Composite Component definition: <cc:interface componentType="dynamicFieldGroupList"> <cc:attribute name="coupletClass" /> <cc:attribute name="form" default="@form"/> <cc:attribute name=

Here is the some parts of the exception : javax

Troubles Iterating Over A HashMap with JSF, MyFaces & Facelets

阅读更多关于 Troubles Iterating Over A HashMap with JSF, MyFaces & Facelets

问题 I'm having some trouble looping over a HashMap to print out it's values to the screen. Could someone double check my code to see what I'm doing wrong. I can't seem to find anything wrong but there must be something. In a servlet, I am adding the following to the request: Map<String, String> facetValues = new HashMap<String, String>(); // Filling the map req.setAttribute(facetField.getName(), facetValues); In one case "facetField.getName()" evaluates to "discipline". So in my page I have the

问题 I'm attempting to migrate an existing JSF application from JSF 1.2 to JSF 2.0. I was using MyFaces 1.2.8 and want to use MyFaces 2.0.5. What I'm experiencing with MyFaces 2.0.5 is that the initially requested page will render properly, but any attempt to navigate to another page will result in a ViewExpiredException . The message is: No saved view state could be found for the view identifier: /SomePageName.jsf (where "SomePageName" is the name of the page that I am navigating away from) If I

How can a custom-validator know which commandButton was clicked

阅读更多关于 How can a custom-validator know which commandButton was clicked

my form has several "submit" buttons, and the validation of some of the fields depends on which was pressed. How can I find that out in my custom validator? The button's client ID get also generated as name of the <input type="submit"> . The name=value of the pressed <input type="submit"> get also sent as request parameters. So you could just check for that in the request parameter map. E.g. <h:form id="formId"> ... <h:commandButton id="button1" ... /> <h:commandButton id="button2" ... /> </h:form> with the following in validate() implementation: Map<String, String> params = context
