I use this code to change the Linkshape of all existing links in my diagram, but the links do not change to bezier.
Also creating a new link after this code always creates cascading links.

It used to work when linksShape was named LinkStyle

function setLinkStyle(a) {
    diagram1.setLinkShape(a);//2 = cascading, 0 = bezier, 1 = poly+-
    if (a === 0) {
        activePattern = anchorpattern0;
    }
    else {
        activePattern = anchorpattern2;
    }
    diagram1.nodes.forEach(function (node) {
        node.setAnchorPattern(activePattern);
    });

    diagram1.links.forEach(function (link) {
        link.setShape(a);
    });
    diagram1.routeAllLinks();
}

using netdiagram 5.5 (dec 8 2015)
Should I call some refresh-function ?
