[OpenLayers-Users] Modifiable Feature - a minimum area

[Chris Jones]

Thanks for taking time to test it. 

In the meantime I created a new version of the ModifyFeature control that
would resize a feature if it became too small, which happened in the drag
vertex method. This seems to work fine if I deselect the feature manually
before deactivating, but if I still have a selected feature on the
deactivation of the new control I get an error 'layer has no properties'
raised in a call to MultipleSelect. Once this error has been triggered the
select feature doesn't function until I reload the page.

In the interest of debugging, I removed all of my custom code leaving
effectively a straight copy of ModifyFeature other than the name of the
class, shown below:

OpenLayers.Control.iModifyFeature = OpenLayers.Class(OpenLayers.Control, {

and 

CLASS_NAME: "OpenLayers.Control.iModifyFeature"

Using the renamed version of ModifyFeature (iModifyFeature) caused the same
error, however using the original ModifyFeature worked perfectly as
expected. Any ideas on what I might be doing wrong?
