When playing with some X++ code, I found an interesting addition that happened in AX 2012 related to form development.
There are 2 new methods that were added to the FormDataSource class, which allow you to very easily and error-free access the underlying QueryBuildDataSource, whether that is for the initial form query or for the queryRun that also contains user filters and sorting.

you can use the 2 new methods:
It might seem as a very minor improvement, but in reality it greatly simplifies maintenance of code on forms, when new datasources are added or existing ones removed/renamed.
That's all for today.
