actionListener in p:ajax

Question

I am a little confused about the attribute actionListener in p:ajax, it does not appear in the taglib of primefaces 5.2.2 and Eclipse thinks so too because it marks it as not existing.

But the code works, the method in the bean is called with an ActionEvent parameter.

<p:ajax event="change" actionListener="#{bean.actionlistenerMethod}" update="stuff" />

So my question is, how can the actionListener work?

Primefaces: 5.2.2
JSF: 2.1.16
JBoss EAP 6.1

Correction: The method with the ActionEvent parameter is NOT called, so the attribute is just ignored... — Ande Hofer, Jun 08 '20 at 11:15
If you are migrating a richfaces 3.3.3 application, why migrate to PF 5.2.2 and not 8? — Kukeltje, Jun 08 '20 at 12:23
Because all primefaces apps in the company are primefaces 5.2.2. It's not really a logical reason, just how it is... — Ande Hofer, Jun 08 '20 at 12:33
Then break out of this... so much has been improved since 5.2... — Kukeltje, Jun 08 '20 at 12:36

As you can see in the taglib and the doc the correct attribute to use would be "listener". Maybe they have covered "actionListener" in the backend just to ommit that kind of errors.

Hello, the problem is that I am migrating a richfaces 3.3.3 project and I would prefer not to touch the beans to much. So when I use the listener attribute I can not use the bean method because it needs an ActionEvent parameter. So I am not unhappy that the actionListener works, but I can not see how. – Ande Hofer Jun 08 '20 at 10:50
We have this in our code even in PF 8. The "listener" is called without ActionEvent param and best used in combination with "event". "actionListener" is not in the TagLib but works and sends the ActionEvent param. Maybe just take a look over here : https://stackoverflow.com/a/21451599/223788 – Przemek Jun 08 '20 at 11:28
