Santiago,
I'm still puzzled why you actually need this and it doesn't seem very
lift-ish. Please take a look on lift-widgets project there is a demo
app as well in the test folder and you can see how we build widgets
usable in any lift app.
But let's get back to your case for one moment. Assume that at the
begining of the page you have:
<lift:foo.bar variable="value"/>
<lift:foo.bar variable="value1"/>
<lift:foo.bar variable="value2"/>
you can have something like:
object variables extends RequestVar[List[String]](Nil)
from your foo.bar snippet you just set
class Foo {
def bar(xml: NodeSeq) : NodeSeq = {
S.attr("variable") map (v => variables(variables.is ::: List(v)))
NodeSeq.Empty
}
}
So the values are accumulated in a RequestVar that later on you can
use when processing other snippets.
If you don't like the RequestVar approach you can consider using a
StatefulSnippet and keep the list of values in your snippet.
Now I'm not completely sure that this is something you're looking for
but this is what I could "compile" from your notes.
Br's,
Marius
