TreeTable | wrong value comparison

[cetincakiroglu]

node1 === node2 is always false. It should use ObjectUtils.equals() to compare.

    equals(node1: TreeTableNode, node2: TreeTableNode) {
        return this.compareSelectionBy === 'equals' ? node1 === node2 : ObjectUtils.equals(node1.data, node2.data, this.dataKey);
    }
