Thanks, Thomas

[Lift] Dynamic Image generation / HttpServletResponse

[Thomas Rynne]

Hi,
 I want to dynamically generate images (actually a graph). I could
write a seperate servlet for this but I'd like easy access to the
Mapper classes and the logged in User etc so would prefer to write it
as a method in lift.

Is there a hook for this? I suppose I essentially want direct acccess
to the httpresponse.

I found some discussion of this here:
http://groups.google.com/group/liftweb/browse_thread/thread/9d6f61f69a20765/d98a32e89e87d317

but I don't know if it was ever implemented, and need some pointers/
documentation if it has been.

thanks for any advice,
Thomas

[Lift] Lists in snippets / Snippet Failure

[Thomas Rynne]

I am trying to render a list of items using bind without success. I
have reduced it to a clean liftweb project with the following in
HelloWorld.scala

  def fruits(xhtml:NodeSeq) = {
  List("apple", "orange", "banana").flatMap(
   fruit => bind("f", xhtml, "name" -> fruit)
  )
  }

And this in index.html
 
 
 


The snippet is not rendered and I get this in the logs:
WARN - Snippet Failure: SnippetFailure(/ -> ParsePath(List
(index),,true,false),Full(helloWorld.fruits),Method Not Found)

What am I missing? I assume there is a problem with the fruits method
signature. Do snippet methods havve to return NodeSeq?

thanks for any advice.
Thomas
