Hello Christian, Allthough the store:read function returns an empty sequense I found that it still triggers the error: 'expressions must all be updating ....', when used within an updating function. I guess this error is unnecesary. The workaround is quite easy by using a void function[1] [1] store:read( $name) => void() mvgr. Rob Stapper

Hi Rob, Could you provide us with a self-contained example? The following example code works as expected:
  store:read('x'),
  delete node <a/>
Best, Christian
