Exposed view in field widget submits node form when filtering
I don't understand exactly whether you're using a form here, but if so, you could give this little module a try, that resolved a similar issue of mine.

http://github.com/Itangalo/Node-creation-block--Drupal-7-

creates blocks for node-forms. If you seperate view from the block (e.g. with Panles) this approach could possibly help you too...
