Where to get docs of creating <wiki:concat> tag

[gus888]

Hi there,

Today, when I reviewed Seam-wiki example codes, I found very interesting tags, e.g. wiki:concat('mailto:', userHome.instance.email). It looks like custom tag, but it is a little different from custom tag. I only found definition in wiki.taglib.xml:

    <function>
        <function-name>concat</function-name>
        <function-class>org.jboss.seam.wiki.util.WikiUtil</function-class>
        <function-signature>java.lang.String concat(java.lang.String,java.lang.String)</function-signature>
    </function>

Anybody can refer to some documents about how to create a tag like this? Thanks.

Look in JavaServer Faces View Definition Framework

Or check Seam Knowledge Base.
