Hi, can you give us the model you are using and tell us which filters(fills) are being refreshed when you delete an item?

The error comes from trying to execute the conditions of the fill on the server, in order to determine if the items in the fill need to be removed because of the delete operation. This all happens under the covers and is based on the filters you have defined in the model.

I fixed the line that caused the NullPointerException for the next release, but I couldn't reproduce it even as it was before the fix. If you give us the model we may be able to suggest a workaround.

Cheers,
