why can't I create comment using rules? Simple rule:

after update node: create new entity with type: "comment"

but after update node, nothing happens...

why that?

UPD, added screenshots of my rule:



UPD2: i can create node by creating entity, but not a comment o_O

UPD3: ok understand what is the problem: i called the content type(machine name) 'task' =)



UPD4: errors while updating node and creating comment:

full error message: "Unable to get variable entity_created, it is not defined."
Because you did not save it. 

Add action of Save Entity.
