coffeescript unexpected INDENT

Question

Sometimes when I edit coffeescript files in Sublime text2 I got errors when compile it to js:

error: unexpected INDENT
                        $.post url,

In sublime text2 editor I see valid indents:

But if I copy paste this code in plain editor I see wrong indents:

click: ->
                            debugger;
                        # delete org here
                        $.post url,

debugger; string has wrong extra indent.

So how to edit coffeescript files in sublime text 2 with pleasure? I got installed coffeescript package in sublime.

My Preferences.sublime-settings file is the following:

{
    "auto_indent": true,
    "auto_match_enabled": true,
    "detect_indentation": true,
    "draw_centered": false,
    "font_size": 11.0,
    "ignored_packages":
    [
        "Better CoffeeScript",
        "Vintage"
    ],
    "indent_guide_options":
    [
        "draw_active"
    ],
    "indent_subsequent_lines": true,
    "indent_to_bracket": true,
    "smart_indent": true,
    "tab_size": 2,
    "translate_tabs_to_spaces": true,
    "trim_automatic_white_space": true,
    "use_tab_stops": true,
    "word_wrap": "auto",
    "wrap_width": 0
}

It looks like you are mixing tabs and spaces. Select View->Indentation and make sure that Indent Using Spaces is checked, then click Convert Indentation to Spaces and you should be all set.
