问题 I\'ve been working with a simple Java EE project using JSF. <h:form id=\"phoneForm\"> <h:dataTable id=\"phoneTable\"> </h:dataTable> </h:form> I tried to set CSS via #phoneTable { ... } , however it doesn\'t work. Upon inspection of the HTML source in client side, it appears that the JSF-generated HTML table gets a client ID in form of id=\"phoneForm:phoneTable\" . I can\'t apply CSS via #phoneForm:phoneTable { ... } , because the colon indicates the start of a pseudoselector and causes an

阅读更多关于 When to use , tag files, composite components and/or custom components?

问题 I started using JSF 2.0 with Facelets recently and got puzzled by new composite components knowing existing <ui:include> and other templating techniques offered by Facelets 1.x. What is the difference between those approaches? Functionally they seem to offer about the same: <ui:param> vs <cc:attribute> , <ui:insert> + <ui:define> vs tag files, reuse of the existing templates. Is there anything besides syntax and clear interface specification in case of composite components? Could performance

问题 I am building a JSF application. I defined the GUI and did the select statements query the database using select. Now I must do the insert statements, but I don\'t know how to read the value of a JSF input component like <h:inputText> and send it to my bean which performs the insert. Should <h:inputText> value be mapped through faces-config.xml , so I can have it in my Java code? 回答1: You need to put all <h:inputXxx> / <h:selectXxx> components in a <h:form> and bind their value attribute to a

问题 I\'ve done tutorial about Facelets templating. Now I\'ve tried to create a page that isn\'t in same directory as the template. I\'ve got problems with page style, because of styles are referenced with relative path like so: <link rel=\"stylesheet\" href=\"style_resource_path.css\" /> I can use absolute referencing by starting with / : <link rel=\"stylesheet\" href=\"/project_root_path/style_resource_path.css\" /> But this will bring me troubles when I\'ll be moving application to a different

阅读更多关于 EL proposals / autocomplete / code assist in Facelets with Eclipse

I tried to activate EL proposals in a Facelets page, but when I hit Ctrl+Space, it doesn't work. I managed to activate JSF tag proposals thank to other questions, but EL proposals aren't working. How can I activate this feature in Eclipse? Is it a known issue? For example: <h:inputHidden id="id" value="#{Ctrl+Space not working!}"/> Eclipse doesn't support this out the box. Even the support in JSP is very limited. Only the properties of <jsp:useBean> and managed beans hardcoded as <managed-bean> in faces-config.xml are available by autocomplete. There are however plugins which supports EL

问题 I would like to output a bit of Facelets code conditionally. For that purpose, the JSTL tags seem to work fine: <c:if test=\"${lpc.verbose}\"> ... </c:if> However, I\'m not sure if this is a best practice? Is there another way to achieve my goal? 回答1: Introduction JSTL <c:xxx> tags are all taghandlers and they are executed during view build time , while JSF <h:xxx> tags are all UI components and they are executed during view render time . Note that from JSF's own <f:xxx> and <ui:xxx> tags

问题 So I\'ve found a few answers close to this, and I\'ve found enough to fix the problem I had. But even so, I\'m curious as to understand the workings around this. Let me illustrate with an example : I have a facelet .xhtml page that looks like this (shortned). <h:form id=\"resultForm\"> <h:panelGroup class=\"search_form\" layout=\"block\"> <h:inputText id=\"lastname\" value=\"#{search.lastname}\"/> <h:commandButton action=\"#{search.find}\" value=\"Find\"> <f:ajax execute=\"lastname\" render=\

问题 Been try to learn JSF, and sometimes I see the URL is *.jsf and sometimes is *.xhtml or /faces/* . Can someone fill my knowledge, please?

问题 I\'m just learning JSF 2 thanks to this site I had learned a lot in such a short time. My question is regarding how to implement a common layout to all my JSF 2 pages and have only the content part of the page refresh not the whole page whenever I click a link/menu from a different panel.

What I am looking for is a way to refresh
