问题 I have got a problem with the HtmlDataTable of JSF 2.0. On my web page, i have got a h:dataTable and some other content, which should only be rendered if the user is logged in.

问题 I have a simple flow in my appliaction - if you fill out and press save on one form (if everything goes well) you are redirected to a second view with a list. Now I wanted to add a message saying "You successfuly added an object" but since I'm using a redirect from what I remember I need to use the Flash scope. And so I did. The problem is that during the first "save" it correctly shows only 1 message but when I navigate back to the form and hit "save" it will show me the current message and

问题 I am getting my current page HTML using Jquery's .html() method like this. <h:outputScript name="js/jquery-1.7.2.js" /> <h:outputScript> function getHtml(){ $('#next').click(function(){ htmlString=$('#wrapper').html(); alert(htmlString); command({param:htmlString}); }); } </h:outputScript> My XHTML page <div id="wrapper"> <form prependId="false"> // My HTML form with some input fields <h:commandButton id="next" value="Submit" action=#{bean.formvalues} onCick="getHtml();"> <h:commandButton> <p

问题 My issue is quite simple : I want to create a composite component with a String attribute, Type. <cc:attribute name="type" /> This attribute will have 3 acceptable values, [TYPE1, TYPE2, TYPE3] Is it possible to say my component will accept only these values ? 回答1: Unfortunately no, you cannot put a compile/buildtime restriction on a composite component attribute value in the cc interface. You can however put a runtime restriction by checking the value in the cc implementation. <ui:param name

问题 So, like the title says in my case height of the extendedDataTable doesn't work, so my table also doesn't scroll because all rows are shown. I'm using richfaces4.0-final version. So here is my piece of code: <rich:extendedDataTable value="#{advancedSearchView.criteria}" var="criteria" height="50px" selection="#{advancedSearchView.selection}" id="table" selectionMode="single"> <rich:column id="criteria_row" filterBy="#{criteria}" filterEvent="onkeyup" width="500px"> <h:outputText value="#

问题 I have a Managed Bean in ViewScope mode. So, when I call some action from this Managed Bean my page do not update. I see that my action is invoked well and returning null (viewscope work flow is OK). So, what am I doing wrong? If I rerender the page using Ajax it works fine. EDIT: My Versions are: JSF 2.1.14 with Primefaces 3.4.1 My Code: @ManagedBean(name = "test") @ViewScoped public class TestMB implements Serializable { private String status; public String getStatus() { return this.status;

问题 I get a String from < p:editor> like this : < b>This is bold text< /b> . I want to show <b>This is bold text</b> in xhtml page. What tag can i use to do that ? 回答1: Use an outputText with escape="true" : <h:outputText escape="true" value="<b>This is bold</b>"/> As stated in the answer to this question: ...Facelets implicitly wraps inline [emphasis added] content in a component as represented by <h:outputText> So, if you don't use an outputText tag with the escape attribute set to true

问题 I want to load pages into a central div when i click my menu links in JSF2.0.
