extend object with editor

This is a one million question.

I am doing this:
$.extend(myTableName.tbl, tbl);
$.extend(myTableName.editor, editor);

Everithing fine with tbl. But with editor when i log myTable.editor it is diferent from editor

Editor {s: Object, classes: Object, i18n: Object, dom: Object, jQuery211018336762349111080.7796777198556728: 2138}

Object {s: Object, classes: Object, i18n: Object, dom: Object, CLASS: "Editor"…}

@Allan do you see the diference? Editor is a Editor instance and myTablename.Editor is anobject
