In my application I need to have null values in a dataset column (of type double). This dataset comprised of several other combined datasets (with identical column formats). I have verified that each of the individual datasets correctly have the null values in them but once they are combined using system.dataset.appendDataset, only the data from the first dataset retains its null values. The rest of the data (from the appended datasets) have the null values converted to 0 (this is bad as the values may not actually be 0 at that time).
Has anyone else seen this? Is this a bug?
I am using version 7.9.10
