getSelection IE7 & IE6 = is null or not an object

[thinkap]

When i try to extract the selected text from the editor i receive the error "getSelection is null or not an object" only happens in ie6 & ie7. it works great in ie8, firefox, chrome & safari.

var editor_name = 'email_ckeditor';


var mySelection = CKEDITOR.instances[editor_name].getSelection();


if (CKEDITOR.env.ie) {
    mySelection.unlock(true);
    selectedText = mySelection.getNative().createRange().text;
} else {
    selectedText = mySelection.getNative();
}

alert( selectedText );
	

also tried without luck

var editor_name = 'email_ckeditor';


if (CKEDITOR.env.ie) {

selection = CKEDITOR.instances[editor_name].getSelection().document.$.selection.createRange().text;
			
} else {

selection  = CKEDITOR.instances[editor_name].getSelection().getNative();
};

alert( selection );

The problem with IE is that it doesn't preserve the selection on different frames. So, in the exact moment you click the link, the selection is lost in the editor.

The solution for it, fortunately, is quite simple. It's enough to add unselectable="on" to you <a> element, so it'll not grab the selection when clicking on it.
