RE: is there a way to pull a session scope variable directly into a jsf tag?

[James Reynolds]

I found out about these implicit variables from reading Kito Mann's
excellent JavaServer Faces in Action.  There are others:

#{cookie.myCookie}
#{facesContext}
#{header['User-Agent']}
#{headerValues['Accept-Encoding'][3]}
#{initParam.adminEmail}
#{param.foo}
#{paramValues.foo[2]}
#{requestScope.foo.bar}
#{view.locale}

Thank you James and Julian.  Your help is greatly appreciated.

Putting all session scoped variables in one place makes sense, but at
this time we have a bunch of code that treats this one value as a
separate attribute.

for the time being I'll use the syntax from James and going forward will
just use a bean.

I must not be reading the right docs because I couldn't find a reference
to "sessionScope".

If you have time, could you mention any docs that have helped you?

Thanks again for your help.
Tom

We put all our session scoped variables into a managed bean which has
session scope. It then becomes easy

#{SessionBean.foo.bar}

There are some implicit variables to simplify accessesing objects in
session or application scope...

#{sessionScope.foo.bar}

Or

#{applicationScope.foo.bar}

I haven't tried this for navigation as you've described, but it works
great for tying object properties to controls.

let's say I have a session scoped attribute (not a component) named foo,
with a value of "bar"

I wanted to create a command button like <h: commandButton action="
#{session.foo}" ...
to pass the string value to jsf for navigation.  I didn't want to put
the value in a managed bean, so used just a session attribute.

but that doesn't work and I've looked for references and can't find one.

is there a way to pull a session scoped attribute directly with a tag?

Thanks for your help.
