Autocreate node references with more than just the title field for the referenced node

I'm interested in this too.. Just thinking out loud..

when the auto-complete field loses focus and contains a value for a node that doesn't exist, why not pop-up/open a new window with the "add node" form for for the relevant content type

Greate module with multiple fields, but without selecting existing nodes: http://drupal.org/project/node_widget

Here are minimum 4 modules that does similiar things:
http://drupal.org/project/node_widget
http://drupal.org/project/nodereference_autocreate
http://drupal.org/project/autocreate
http://drupal.org/project/noderefcreate

Couldn't it be possible to pack all features in one module?

Also looking for something like this. Anyone come up with anything yet?

I found a module that works almost perfectly for this:

http://drupal.org/project/popups_reference

However, there are some javascript conflicts when adding a new node (specifically, when uploading images and things like that), and it won't automatically insert the node title into the reference field. Also, the project is looking for a new maintainer. Any takers?

I'm interested too.

I'm using node relationships now, which work pretty well. Use the "Create & Reference" action.

But it needs an alpha1 or dev version of JQuery Update, right ? Is it stable enough ?

It took a little work to get properly set up, but it works fine for me now.
