Hot to logic in rendered tag

If someone could help me with this, it is quite puzzeling.  I see examples
using && || in the rendered tag but it does not work for me.

I have the following:

193 <t:commandLink
194        rendered="#{myBean.showBtn && myBean.anchor.anchored}"

MyBean (myBean) has a class called Anchor that has a method isAnchored()
which returns a boolean.
There is also a method that returns a boolean called getShowBtn().

I get the following error
SEVERE: Error Rendering View[/web/gro/PtGroGroup.xhtml]
com.sun.facelets.FaceletException: Error Parsing /web/Page.xhtml: Erro
r Traced[line: 194] The entity name must immediately follow the '&' in the
entit
y reference.
        at
com.sun.facelets.compiler.SAXCompiler.doCompile(SAXCompiler.java:234)



---
any ideas?

thanks

Re: Hot to logic in rendered tag

Posted by Mike Kienenberger <mk...@gmail.com>.
Facelets requires page code to be valid xml, unlike jsp page code.

The simplest solution is to use "and" instead of && and "or" instead
of "||" (and "gt", "lt", "ge", "le" etc).

Or you can try to figure out the correct escaping.

Probably something like &amp;&amp;
