FacesValidator is not working
Hi there I got a problem with validation of html components via a seperate Validator instance.
The validation is never called! The SYSO is never written out to console!
I already tried to redeploy, update project, clean and restart, reinstall glassfish tools, reinstall glassfish, reinstall eclipse.
This is my project setup:
registration.xhtml:
<?xml version='1.0' encoding='UTF-8' ?>

<br />

msg.setSeverity(FacesMessage.SEVERITY_ERROR);
throw new ValidatorException(msg);

Version:
- GlassFish Server Open Source Edition 4.1.1 (build 1)
- Eclipse Jee Neon.1 Release (4.6.1) Build id: 20160913-0900
- JSF 2.2.14 Release of 15. Nov 2016 (was originally 2.1)
- JAVA_VERSION="1.8.0_102" OS_NAME="Windows" OS_VERSION="5.2" OS_ARCH="amd64"
- Maven 3 (I think)
- Java EE 7u2 from http://www.oracle.com/technetwork/java/javaee/downloads/index.html
I used the Java EE 7u2 installation to configure my project.
As I am completely new to this JSF, Glassfish, JSP and other web development stuff I do not have any clue, why this is not working as several examples has suggested it like this. Can someone please provide me an answer or any idea why this is not working?
NOTE: I am running the Server in Eclipse with the Glassfish Tools
Solution
AS I found the answer on myself the following code is happening to not throw a runtime error, just a compiler warning:
<input jsf:id="submit" name="submit" value="Register" type="submit">
<f:ajax render="@all" listener="#{registrationBean.register}" />
</input>
Changing it to:
<h:commandButton value="Submit" action="#{registrationBean.register()}" />
This has resolved my issue and the EqualsValidator is found and called!
