[OpenLayers-Users] changing the state of a selected feature

[Jorge Gustavo Rocha]

Hi Marco,

I don't use the toState method, but changing the property directly does
work.

For example:
/*
* allow editing the selected feature
*/
(...)
featureToBeModify = someVecLayer.selectedFeatures[0];
theCorrespondingForm.getForm().items.each(unsetReadOnly);
(...)
/*
* save
*/
if (featureToBeModify.state != OpenLayers.State.UPDATE) {
	featureToBeModify.state = OpenLayers.State.UPDATE
}
var rec = theCorrespondingForm.getForm().getValues();
featureToBeModify.attributes.one = rec.one;
featureToBeModify.attributes.two = rec.two;
(...)      
saveStrategy.save();

As you can see, state can/should be changed to allow the feature be
written in the save operation.

I hope it helps,

Jorge
