Menu
I'm trying to accomplish a small tweak in a Facelets/JSF environment. I know next to nothing how all of it fits together.
I have a value defined on various pages as "title"
<ui:define name="title">PageUID_123</ui:define>
On another page I am referencing this with:
<ui:insert name="title"/>
I can wrap html tags around the insert just fine, but I need to be able to output the value of "title" as an attribute of another element. My end goal is for it to render in html like this:
<meta name="pageid" content="PageUID_123"/>
If I try putting the insert tag in the content="" bit, it throws a parsing error. Is there a way to do this?

I don't have a working environment in front of me, but I believe you don't want to you use <ui:define>, but instead you want to use <ui:param> and then use ${x} or #{x} (or forget which or if it matters) to pull them out.
So, for you example you would have:
<ui:param name="title" value="PageUID_123" />
And then:
<meta name="pageid" content="${title}"/>
My only concern with that is that you are using include to have nice templates, i.e.
template:
<html>
<head>
<meta name="pageid" content="${title}"/>
</head>
<body>
<ui:insert name="content" />
</body>
</html>
Inner page:
<html xmlns="...so many">
<ui:param name="title" value="PageUID_123" />
<ui:define name="content">
<!-- content goes here -->
</ui:define>
</html>
And I really don't know if that will fly...
Edit: You may want to try ${title} or #{title} just for kicks the way you're doing it now, it might Just Work.
