To get it directly from a request parameter, you'd need to do
"$requestParameter{form:in}" because the "id" you set here is not the
"id" in the HTML. Do a browser "view source" to see what I mean.

You are missing:
value="#{requestScope.in}"
The "id" property is not used by JSF to access the data. The "id" in
JSF gets translated to a "client ID" which end up looking like
"form:in". This is what is used in the HTML for the component
(typically). You can also use the "client ID" in java code to locate
the "component" and from the component access the data. If you don't
bind the value to anything (as you did above), you'd need to get the
component in this way to get its value. This is not common, though.
Binding the value is the better approach.

No need... see above. You can select the appropriate scope in the EL
binding for the value field. Or use a manged bean.

See above.
Good luck!
