Sharepoint Extended Lookup Field

When designing an Sharepoint implementation I started out with OOTB Sharepoint behaviour. I added a LookupField to the list and pointed it to another list. But OOTB all listitems from the referenced list would show up in the dropdown as options. I wanted to be able to control which options would be shown.

I've found an open source fieldcontrol at http://extendedlookup.codeplex.com/ which would be able to do just that by using a view. Unfortunatly it didn't work right-away for me, probably due to some updates from SP-hotfixes. After making some minor changes, i was able to get it working again.

When fiddling with the control I noticed that when a selected item wasn't included in the view it would revert to the first/default-value. Once again i made a minor change, which would make it able to add the selected-item as an option.

Update: just noticed the archived comment at http://extendedlookup.codeplex.com/:
