You need to do a "deep copy" of the data model array. I thought there was a method in qx.lang.Array to do that, but its clone() method is shallow, not deep. You should be able to use this untested snippet, though: var treeBData = qx.util.Serializer.toNativeObject(treeA.getDataModel().getData(), null); treeB.getDataModel().setData(treeBData); Derrell
