How to set predecessors in project manament tab?

[dariuszm]

Hi,
How to add predecessors to phases tasks by script? I'm trying to do it by this action script, however it's not working for me.

var myPhase = item;
var myPhaseGantt = myPhase.project;
var myPhaseGanttChildren = myPhaseGantt.children;
var myPredecessors = [];
var testPredecessor = myPhaseGantt.children[0];
myPredecessors.push(testPredecessor);
myPhaseGantt.children[1].predecessors = myPredecessors;
var endDebug = 1;

item.project.children[i].predecessors is a read-only property, you cannot set predecessors by script
