[OH2.4.0.S1440] Maybe an error - update of items throws error

I’m on snapshot 2.4 1440.

If I delete an item or a group from item file, I get this error log:

I cannot reproduce
what bindings are you using and what is the Item config?

Something else is wrong… your OH2 process is complaining about not being able to open files within the userdata/cache subdirs…

I’ve done that before. Done that now again. It looks that if I change a item the group membership gets not updated. I will do some tests and report later.
