How to filter collection for removed objects

[schlonzo]

hi all,

I am trying to use Except (like in the multitouch example) to filter removed objects from my collection. Except seems to monitor all values within my objects, so while I drag my object around it registers in the except node.

Could this be done with the Except(Selector) node? How do I use the selector pin?
Any other hints also appreciated!

I think you have to declare your draggable object as a class, because a record creates a new instance on every change.
