JSF Bootsfaces components not showing

Question

Today I was working on our application for a school project. We had no problems with the our Bootsfaces but suddenly I can't seem to get the components to show (see image). I don't know what's causing this unexpected behaviour because it worked before. Nothing has been changed to the .xhtml page. The error log in the Chrome console and the Payara console are both giving 0 errors.

I am using Payara 5.181 and Java EE 7.

Edit:

Removing the "generated" folder in the Payara server and restarting the PC seems to solve this problem, but after a while (can't reproduce exactly why) the page turns blank again.

.xhtml file

@JasperdeVries This does not work unfortunately.. It shows the same empty page. — Guido, Apr 18 '18 at 12:05
What is the welcome page in the web.xml? Is it mapped to `index.jsf`? Does it work if you add `index.jsf` to the URL in the browser? — Jasper de Vries, Apr 18 '18 at 12:08
@JasperdeVries We are using the following code: ` pickCartracker.xhtml ` to redirect to the homepage. It does not work when I link to `http://localhost:8080/RegistrationSystem/pickCartracker.xhtml` — Guido, Apr 18 '18 at 12:09

@JasperdeVries Do you have any idea why it worked before though? — Guido, Apr 18 '18 at 12:23
Maybe you were using different URL's in the browser (ending in `.jsf`) — Jasper de Vries, Apr 18 '18 at 12:24
With modern JSF these entries in the web.xml are not needed anymore... — Kukeltje, Apr 18 '18 at 12:45
@JasperdeVries It just worked, and I reployed again and I'm getting the same problem again. Any idea's? — Guido, Apr 18 '18 at 12:53
Just restarted my pc and removed everything from the "generated" directory in the payara server and it worked again.. I don't get it — Guido, Apr 18 '18 at 13:13
@JasperdeVries The problem keeps re-appearing. Sometimes deleting the "generated" directory in the payara server and restarting my PC fixes the issue (but not always).. It's pretty weird — Guido, Apr 24 '18 at 08:01
Please update your question to what exactly is happening and what your current configuration exactly is. — Jasper de Vries, Apr 24 '18 at 08:17

curiously in my case I had a similar problem, and it turns out that so many modifications and tests prove that this dependency in my pom.xml generated that the bootsfaces components were not rendered. My solution was to eliminate this dependence.
