expression: getting attribute value from the previous tree

Question

Hello,

I have 'tree' entity and I want to get for the (code) attribute 'tree_segment' by default the same value that was given to the previous tree, starting from tree no 2. What's the correct expression?

Hi Lauri,
You can access the previous tree information in this way:

parent()/tree[idm:position($this/parent()) - 1]/tree_segment

Don't forget to specify the condition, that must be:

idm:position($this/parent()) > 1

Thanks.
