Problem using include in Facelets
I have problems including a facelet template. I wanted to split some content up, so that I can reuse it somewhere else.
So I changed this code:
<!DOCTYPE html>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="/layout/template.xhtml">
<ui:define name="head">
<title>Title</title>
</ui:define>
<ui:define name="header">
<h3>Header</h3>
</ui:define>
<ui:define name="content">
<table><tr><td>table</td></tr></table>
</ui:define>
</ui:composition>
To this:
<!DOCTYPE html>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="/layout/template.xhtml">
<ui:define name="head">
<title>Title</title>
</ui:define>
<ui:include src="/admin/admin_generic.xhtml"/>
</ui:composition>
And inside admin-generic.xhtml I wrapped the code in a ui:composition.
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<ui:define name="header">
<h3>Header</h3>
</ui:define>
<ui:define name="content">
<table><tr><td>table</td></tr></table>
</ui:define>
</ui:composition>
But nothing is shown. I just get a blank page, with no errors. Is it wrong using ui:composition? I have tried with ui:component but that didn't help either.
Update: According to my Facelets Essentials Guide, it says:
The
ui:includetag can be used to include another Facelets file into your document. It simply includes whatever source file you specify. You can include any Facelets file that hasui:componentorui:compositiontags (which trim the content outside themselves) or simply a fragment of XHTML or XML.
Is that what is going on? Is the content outside of the include trimmed away? How can I just include the page, without the content outside being trimme开发者_Python百科d?
The <ui:define> has to be placed in an <ui:composition> or <ui:decorate> with a template containing the appropriate <ui:insert> tags. You've moved it to an <ui:composition> without a template. No template means no content.
Technically, to achieve your requirement, you have to replace the <ui:include> by <ui:insert>.
<!DOCTYPE html>
<ui:composition
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="template.xhtml">
<ui:define name="head">
<title>Title</title>
</ui:define>
<ui:insert />
</ui:composition>
And declare the above page (I assume it as somepage.xhtml) as template in admin_generic.xhtml.
<!DOCTYPE html>
<ui:composition
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="somepage.xhtml">
<ui:define name="header">
<h1>Header</h1>
</ui:define>
<ui:define name="content">
<table><tr><td>table</td></tr></table>
</ui:define>
</ui:composition>
Note that you have to open admin_generic.xhtml in the browser instead. If your intent is to open somepage.xhtml in browser, then the <ui:define> really has to stay in somepage.xhtml. You can however replace the body of <ui:define> by a simple <ui:include>.
<!DOCTYPE html>
<ui:composition
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="template.xhtml">
<ui:define name="head">
<title>Title</title>
</ui:define>
<ui:define name="header">
<h1>Header</h1>
</ui:define>
<ui:define name="content">
<ui:include src="admin_generic.xhtml" />
</ui:define>
</ui:composition>
It allows for <ui:composition>, so you don't necessarily need to put the <table> to root.
<!DOCTYPE html>
<ui:composition
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<table><tr><td>table</td></tr></table>
</ui:composition>
I solved this by removing the <ui:composition> and the <ui:define> and just adding the namespace directly in the <table> like this:
<table class="adminform" xmlns="http://www.w3.org/1999/xhtml"
xmlns:s="http://jboss.com/products/seam/taglib"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:a="http://richfaces.org/a4j">
So now my page looks like this:
<ui:define name="content">
<ui:include src="/admin/admin_generic.xhtml" />
</ui:define>
加载中,请稍侯......
