Hello!
I created a root ProductPartition for AdGroup in shopping campaign, and set its maximum price (0,10 for example).
But when i try to get this ProductPartition via API, i get NULL insted of 0,10.
If a add some additional partitions inside root, there is no problem to get their parameters and price, but with root it does not work :(
ProductPartitionTree partitionTree = ProductPartitionTree.createAdGroupTree(new AdWordsServices(), adWordsSession, request.getAdGroupId());
ProductPartitionNode rootNode = partitionTree.getRoot();
rootNode.getBid(); //returns NULL, but really it has valid value in web interface
