How to solve problem with error xxx "is not a constructor" ?

Solution for Extjs 2.3.0 (but i think it work for all version from 2.x and above)

If you see an error that  Lollypop is not a constructor (in general that something is not a constructor) that should gives you a clue that  that the javascript file that  containing   Lollypop (in general, object)  has not been loaded for some amazing reason into your marvellous the page.

It can be 2 reason....
 a) in 99% you simple didn't include this javascript file into page at all
so you should include this file using <script> tag , for example
<script src="scripts/my-candies/Lollypop.js"></script>

b) in rare case you misspell something with names.

Problem solved.
