what i usually do is savethis to a local var.
addControl: function(pCntrlType) {
var obj;
var self = this;
switch (pCntrlType) {
case "TXTB":
obj = new Element('input', {
'id': 'textbox1',
'styles': {
position: 'absolute'
},
'events': { 'click': function() {
grabControl(self);
}
}
}).inject($('tdMainCenterRight'));
break;
}
this.makeElementDragable(obj);
},
