Customizing the Logic of a Core Component

Question

Hi everyone,

I am following this page(Delegation Pattern for Sling Models · adobe/aem-core-wcm-components Wiki · GitHub)and try to customize title component,but it still returns the originial title.

Is there something else i need to do besides create pageHeadline component in ui.apps and model file in models folder?For example add something into the core/pom.xml or create a new title htl file in crxde lite?

Thanks in advance!

My code below:

training\ui.apps\src\main\content\jcr_root\apps\training\components\pageHeadline\.content.xml

<?xml version="1.0" encoding="UTF-8"?>

<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"

jcr:primaryType="cq:Component"

jcr:title="Page Headline"

jcr:description="Display Page Heading"

sling:resourceSuperType="core/wcm/components/title/v3/title"

componentGroup="TrainingProject - Content"/>

training\core\src\main\java\com\adobe\training\core\models\PageHeadlineModel.java

package com.adobe.training.core.models;

import com.adobe.cq.wcm.core.components.models.Title;

import com.day.cq.wcm.api.Page;

import org.apache.sling.api.SlingHttpServletRequest;

import org.apache.sling.models.annotations.Model;

import org.apache.sling.models.annotations.Via;

import org.apache.sling.models.annotations.injectorspecific.ScriptVariable;

import org.apache.sling.models.annotations.injectorspecific.Self;

import org.apache.sling.models.annotations.via.ResourceSuperType;

@Model(adaptables = SlingHttpServletRequest.class, adapters = Title.class,resourceType = "training/components/pageHeadline")

public class PageHeadlineModel implements Title {

@ScriptVariable

private Page currentPage;

@Self @Via(type = ResourceSuperType.class)

private Title title;

@Override

public String getText() {

return "new title"+title.getText();

}

Hi @zonghuiliu

Please try to override all the remaining default getter function used in the title core class in your custom class.

@override
public String getType() {
        return title.getType();
    }

    default String getLinkURL() {
        return title.getLinkURL();
    }

    default Boolean isLinkDisabled() {
           return title.isLinkDisabled();
    }

    default String getExportedType() {
        return title.getExportedType();
    }

Hope this helps!
