[J.Alejandro Martinez Linares]

Hi peoples, i have a question for all you, the main code of my project is this, and i have dudes, because maibe, there are problem beetwhen "OpenLayers.Control.ModifyFeature" and "OpenLayers.Control.SelectFeature"
and i want to know if i have to take a care when i use them in a same app, here is my code below, take a look and tell me about it, because i have

//------------------------------------------------------------------------------------------------------
feature.layer is null
http://localhost/personal/assets/ge/OpenLayers-2.11/lib/OpenLayers/Control/SelectFeature.js
Line 324
//------------------------------------------------------------------------------------------------------

and it occurr when i select a feature and save changes in it and next i try to select another feature


//------------------------------------------------------------------------------------------------------

modifyControl = new OpenLayers.Control.ModifyFeature(vlayer,

      autoActivate : true,
	 onModificationStart : function(feature)

		console.log(ll);
		},
	 onModificationEnd : function(feature)
		{
		if (intersec(feature))
			{

			}
			else
			{
			Ext.MessageBox.show({
				title: 'Error',
				msg: 'Esta intentando mover puntos fuera de lo permitido',
				buttons: Ext.MessageBox.OK,
				icon: Ext.MessageBox.ERROR
			});

			}
		modifyControl.unselectFeature(feature);
		}
}
);

drawControl = new OpenLayers.Control.DrawFeature(
vlayer,
OpenLayers.Handler.Point,
{
	handlerOptions :
		{
          multi : false
		},
	featureAdded : function(feature)
		{
		if (intersec(feature))
			{

			}
			else
