NI TestStand Idea Exchange
TestStand now works incredibly well with LabVIEW Classes, but there is a slight annoyance with the fact that you cannot call a Dynamic Dispatch VI with an empty Object Reference. The implication of this is that when you want to use a .lvclass, for every class instance you have to call a VI that does nothing more than return a wrapped class constant which then populates an Object Reference. Technically this is not a problem, but it means that your Sequence becomes very quickly littered with these VI's and it would be nice if there was a way within the LabVIEW module adapter settings for a class member call if when you first call a Dynamic Dispatch VI that, as within LabVIEW you can just pass in a class constant rather than a previously populated Object Reference.
The Problem - All the LabVIEW calls prefixed with 'NEW' are simply returning a class constant.
A Potentially more integrated way of doing this
The Dynamic Dispatch input has the option of either passing in an Object Reference, or a class constant.
All compatiable classes are listed in the value box now - either as .ctls, or alternatively as .lvclasses. This could also possibly be more akin to what happens in labVIEW when you call a Class which has available overrides that it gives you a tree view of the class hierachy to choose from.
Another way you could do this is to have a checkbox adjacent to the 'Class Path:' or 'Member Name:' named 'First Call' or 'New' or 'Construct' that then changes the 'Derived Class
