```
    Set the flow for the KnowledgeFlow to edit. Assumes that client has loaded a Vector of beans and a Vector of connections. the supplied beans and connections are deep-copied via serialization before being set in the layout. The beans get added to the flow at position 0.
    
    Parameters:
    
    v - a Vector containing a Vector of beans and a Vector of connections
    
    Throws:
    
    java.lang.Exception - if something goes wrong
  - getFlow
```

```
    Gets the current flow being edited. The flow is returned as a single Vector containing two other Vectors: the beans and the connections. These two vectors are deep-copied via serialization before being returned.
    
    Returns:
    
    the current flow being edited
    
    Throws:
    
    java.lang.Exception - if a problem occurs
