Hi,
Whenever you create a new input variable for your workspace and recompile, there is a need to repopulate all drop downs by “attaching”. Unfortunately, I always forget how to do this 
Would really appreciate if someone could remind me!
Best,

Hi,
there are a couple of tricks here.
First as you probably know, if you have a wsp with funcitons attached - then alter something so it does not compile, then all functions attched will be removed from its tables and graphs. → to handle this: press a “soft compile” use ctrl + F7 in order to check the code without compiling. If not, fix the problem and compile only when you know the code works.
Second. When you have “fill” vector(string) attached to string input controls. These might need to be re-attached.
Open the workspace browser. Take the fill-vector function. Drag-and-drop it onto the empty string input variable. Then you will have regained you drop-down.
Hope that answers your question?

Thanks for replying! The soft compile is a bit of a game changer from this angle
