Hi,

I'm writing a wizard to be used for data import into our app. The data
files are not huge, but large enough (1-5mb) that I shouldn't hold on to
them longer than necessary :-)

Basically the wizard has a few steps:

1) Select the file
2) Show results of parsing the file, errors, warnings etc
3) Do the import
4) Show import status

What is the best way to handle this in Lift. I've seen that something is
being worked on wrt wizards, but haven't see anything concrete. 

What is the best way to hold on to the data while the wizard is active
but ensure that it's freed if i.e. the user navigates away (not from the
app but from the wizard) Will this be taken care of automatically by the
lift gc if the data is referenced in a closure?
