How were the features loaded in the layer in the first place?
Unless the features were added on the client (i.e. in a Javascript function written by you), when the extent changes the default behavior for Vector layers backed by WFS is to fetch new features from the server.
You can customize the behavior of the Vector layer with regard to remote sources by providing a properly configured strategy. Examples like this one are available in the examples page.
This is a two-step procedure with ArcGIS. This method is also suited for automating with ModelBuilder or Python.
- Eliminate Polygon Part (Data Management). Use this to fill the polygon hole. For this example I specified 50% as the condition in the tool parameters
- Erase (Analysis). Erase the newly created polygon with the original polygon to get the polygon of the hole

check out OpenLayers Editor here. it has tool for merging two polygon (merge selected geometry) so you can draw a polygon on to hole then merge two polygons.
beside this you should check out JTS Topology Suite for javascript implementation here.
i hope it helps you...
