[OpenLayers-Users] Can I prevent OpenLayers from losing my WFS-T feature edits?

[Andreas Hocevar]

A workaround is to configure a bigger ratio (e.g. 2) for the
OpenLayers.Strategy.BBOX, which means that a larger extent of features
is loaded with every GetFeature request. Another strategy that I've
been using is to display the layer using WMS, and use the GetFeature
control to only "check out" the clicked feature for editing. Then you
can use before* listeners to ask the user if they want to save when
another feature was clicked, or you can disable the GetFeature control
until editing is done.
