RE: extending tree2

[Dennis_Byrne]

You don't need to the myFaces source, just the binary distribution.  If you are already using myfaces, then you already have it. The rest is this, Edwin:

1.) Compile the two classes.
2.) Get a tag library descriptor (a .tld file under /WEB-INF/tags is best.), I'll just copy and paste one below.
3.) Look at the post w/ long lines of code, use the xml snippets in your faces configuration.
4.) In JSP, put this at the top
<[EMAIL PROTECTED] prefix="a" uri="yourURN" %>
5.) Use tree3 like this:

<a:tree3 expandAllInit="true" ... />

BTW, expandAllInit is false by default. I've only used this with the 1.0.9 version.  Let me know if you stumble.
