open fun setAutoGrowNestedPaths(autoGrowNestedPaths: Boolean): Unit
Set whether a binder should attempt to "auto-grow" a nested path that contains a null value.
If "true", a null path location will be populated with a default object value and traversed instead of resulting in an exception. This flag also enables auto-growth of collection elements when accessing an out-of-bounds index.
Default is "true" on a standard DataBinder. Note that this feature is only supported for bean property access (DataBinder's default mode), not for field access.
