[Pas2js] htmlwidget in pas2j 2.2.0: pas.JS.isUndefined is not a function

[Luca Olivetti]

As per the subject, I'm using pas2js 2.2.0 with fpc 3.2.2 and lazarus 2.2.2.

Since I had problems with Pas2JS_Widget, I'm now back to the basics 
following this article:

https://www.freepascal.org/~michael/articles/pas2js1/pas2js1.pdf

and while the first method (page 12, plain javascript classes) works, if 
I try to use the second one (using the httpwidget unit, not the 
webwidget one as the article says) I get this error in firefox:


Uncaught TypeError: pas.JS.isUndefined is not a function
     EventEntry webwidget.pas:2640
     cb rtl.js:256
