the source file to create the data vector
This is not a problem with javaScript as much as it is with the update architecture. You can see the same problem by creating a data vector through the UI and then changing its frame properties. If the vector is not being used in a curve then the vector will not be updated. This problem results because there is no attempt made to update vectors in the update thread. Only curves, data objects, data sources, and scalars are updated. If one of these updated objects happens to be dependent upon a given vector, then the vector will also be updated, else it will not.
