javax.servlet.ServletException: org.primefaces.context.RequestContext.getCurrentInstance - maven

Question

I am making a maven project using JSF 2.2, Primefaces 6.2 on Eclipse. I recieved the following error when I tried to use <p:chips id="chips" /> that is displayed on Primefaces' website:
javax.servlet.ServletException:
org.primefaces.context.RequestContext.getCurrentInstance(Ljavax/faces/context/FacesContext;)Lorg/primefaces/context/RequestContext;
Even though I have removed the changes I made on my .xhmtl page and took it all the way back where it was running, I still receive the same error and my webpage is not running.
Here is my pom.xml for primefaces component:
<!-- https://mvnrepository.com/artifact/org.primefaces/primefaces -->
<dependency>
<groupId>org.primefaces</groupId>
<artifactId>primefaces</artifactId>
<version>6.2</version>
</dependency>
Could that be some kind of Eclipse - Maven compile error? I have cleaned, re- built the project and even deleted .m2 file but nothing changed. All help will be appreciated.
Also here is the exception and stack trace:
2018-05-15T08:34:34.986+0300|Warning: StandardWrapperValve[Faces

As far as I can tell version 6.2 added the method in question. Perhaps you have an older version in your application? Check in the web-inf/lib directory. For reference: RequestContext 6.2 and RequestContext 6.1
