           Summary: scalar's tag names in equations don't follow tag name
                    changes in parent vectors
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: netterfield astro utoronto ca


Version:           1.4.0_devel (using KDE 3.5.6, Kubuntu (edgy) 4:3.5.6-0ubuntu1~edgy1)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.17-11-generic

When the tag name of a vector is changed, then everywhere it is used gets the new name (because data objects store vector pointers, not tag strings).

However, this does not follow to derived scalars: if a derived scalar is used in an equation, and the parent vector's tag name is changed, then the equation quits working, rather than following the vector's new name.
