CommandLink does not trigger a listener action, but commandButton works fine

I want to call one method via a link from Facelets:

My Facelets code is as follows:

<h:commandButton value="A" actionListener="#{customerData.searchedCustomerListA}" />

<h:commandLink value="A" actionListener="#{customerData.searchedCustomerListA}"/>

The reverse bean code is as follows:

public void searchedCustomerListA(ActionEvent ae){
    customerName = "A";
    leftCustomerListAvailable.clear();
    if(customerDataBean.getSearchedCustomerList(customerName)!= null)
        leftCustomerListAvailable =customerDataBean.getSearchedCustomerList("A");
}

The same code works for <h:commandButton>, but does not work for <h:commandLink>. How is this caused and how can I solve it?

<div class="control-group">
    <div class="controls">
        <h:commandButton value="Login" action="#{usrCtrl.login}" class="btn btn-primary"/>
        <h:commandLink action="#{usrCtrl.register}" value="test" immediate="true"/>
   </div>
</div>
</h:form>

Read the JSF and the “immediate” attribute - Command Components to see why it works.

In my case, the cause of this problem was a poorly configured URL rewrite filter. One of the filter patterns is inadvertently mapped http://localhost:8080/mysite/javax.faces.resource/jsf.js.xhtml?ln=javax.faces, which prevents jsf.js from loading. Check this answer: Pressing h: commandLink raises an Uncaught ReferenceError: mojarra not defined .
