Hey Knut, Araz, The order for arrays is guaranteed according to the JSON standard i believe. However for the objects property order is not. (Just like in Javascript)
But we (DHIS2) don't seem to always return the array in the same order from the server side, so in that case you can't really trust the order like you said. Rework the list into a `Map`(JS Object) like Araz says will work. I just coded you up a small function that does the transformation. See the following gist link. https://gist.github.com/Markionium/0e55e774b3c554521040#file-transformattributes-js Regards, Mark On Sun, Nov 22, 2015 at 10:08 AM, Araz Abishov <araz.abishov.g...@gmail.com> wrote: > Hi Knut, > > What are you using for parsing JSON (which library)? > > In general you should never rely on order of items in JSON.
