I am using an expression plugin tag to assign nulls to some points on a spline and then if the nulls move code in the execute function moves the corresponding point with the null.  This works but I want to pass the original number of spline points from a function outside execute to exectue. I was trying this:

    
    
      
    class SplineNull : ExpressionPluginTag{.....
    
    
    
    
    SplineNull::Test()  
    {  
     var bc=GetContainer();  
      pObj=GetObject();  
     var e=pObj->GetContainer();  
     println(e);  
     e->SetData(SPOLDY,4);//pObj->GetPointCount());  
     SetContainer(e);}
    
    
    
    
    SplineNull::Execute(doc, op)  
    {  
     var b = op->GetContainer();  
     println(b);  
     println(spnew,"   ",b->GetData(SPOLDY));}
    
    
    
    
    So anyway from the printlns I can see that I'm getting different conainers.  I was thinking that same object and therefor same container.  Maybe I'm making a new container with GetConainer().
    
    
    
    
    Anyone have any ideas?
