问题
I am trying this new functionality, and when I try to use set variable activity inside foreach loop I cannot select a variable that I declared in a pipeline. Also inside IF activity. Is it supposed to behave like this? That you cant set variable inside some inner activities, only at the root level of the pipeline?
回答1:
This is a known bug, where set variables and append variables activities are not correctly detecting changes when they're nested in another activity. Actively working on a fix for, hopefully will resolve this problem soon :)
