This issue occur when i update my gojs version from 2.1.22 to 2.3.11
function PoolLayout() {
go.GridLayout.call(this);
this.cellSize = new go.Size(1, 1);
this.wrappingColumn = 1;
this.wrappingWidth = Infinity;
this.isRealtime = false; // don't continuously layout while dragging
this.alignment = go.GridLayout.Position;
// This sorts based on the location of each Group.
// This is useful when Groups can be moved up and down in order to change their order.
this.comparer = function (a, b) {
var ay = a.location.y;
var by = b.location.y;
if (isNaN(ay) || isNaN(by)) return 0;
if (ay < by) return -1;
if (ay > by) return 1;
return 0;
};
}
go.Diagram.inherit(PoolLayout, go.GridLayout);
PoolLayout.prototype.doLayout = function (coll) {
var diagram = this.diagram;
if (diagram === null) return;
diagram.startTransaction("PoolLayout");
var pool = this.group;
if (pool !== null && pool.category === "Pool") {
// make sure all of the Group Shapes are big enough
var minsize = computeMinPoolSize(pool);
pool.memberParts.each(function (lane) {
if (!(lane instanceof go.Group)) return;
if (lane.category !== "Pool") {
var shape = lane.resizeObject;
if (shape !== null) { // change the desiredSize to be big enough in both directions
var sz = computeLaneSize(lane);
shape.width = (isNaN(shape.width) ? minsize.width : Math.max(shape.width, minsize.width));
shape.height = (!isNaN(shape.height)) ? Math.max(shape.height, sz.height) : sz.height;
var cell = lane.resizeCellSize;
if (!isNaN(shape.width) && !isNaN(cell.width) && cell.width > 0) shape.width = Math.ceil(shape.width / cell.width) * cell.width;
if (!isNaN(shape.height) && !isNaN(cell.height) && cell.height > 0) shape.height = Math.ceil(shape.height / cell.height) * cell.height;
}
}
});
}
// now do all of the usual stuff, according to whatever properties have been set on this GridLayout
go.GridLayout.prototype.doLayout.call(this, coll);
diagram.commitTransaction("PoolLayout");
};
this.poolGroupTemplate =
$(go.Group, "Auto", groupStyle(),
