示例1: refreshNodeConnection

/**
* Refresh this node SplineConnection's children (its decorations). Calling the locator's relocate() moves these decorations.
*
* @param conn
* the node connection
* @param force
* force a refresh that might cause infinite loops
* @return true if we could refresh (edit part and figure exist)
*/
