Hi, I was used to work with WCMUsePojo, now I am starting to work with Sling Models. I am reading some documentation and I have followed some examples,

that makes all sense to me but my object @ValueMapValue is getting null and I can't find the problem. Can some please help me to understand what am I missing?

I have a component with a dialog to configure it.

I am very gratfull in advance

my component name is featuredicons and it has this dialog:

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

                </items>

            </tabs>

        </items>

    </content>

</jcr:root>

my model:

@Model(adaptables = Resource.class)

public class IconModel {

    private final Logger LOG = LoggerFactory.getLogger(getClass());

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String icontText;

   

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String iconCode;

   

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String iconCharacter;

   

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String iconColor;

   

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String iconBgColor;

   

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String openNewtabIcon;

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String urlLinkIcon;

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String urlIconInt;

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String urlIconProtocol;

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String urlIconExt;

    public Logger getLOG() {

        return LOG;

    }

    public String getIcontText() {

        return icontText;

    }

    public String getUrlIconInt() {

        return urlIconInt;

    }

    public String getUrlIconProtocol() {

        return urlIconProtocol;

    }

    public String getUrlIconExt() {

        return urlIconExt;

    }

    public String getIconCode() {

        return iconCode;

    }

    public String getIconCharacter() {

        return iconCharacter;

    }

    public String getIconColor() {

        return iconColor;

    }

    public String getIconBgColor() {

        return iconBgColor;

    }

    public String getOpenNewtabIcon() {

        return openNewtabIcon;

    }

    public String getUrlLinkIcon() {

        return urlLinkIcon;

    }

    public void setIcontText(String icontText) {

        this.icontText = icontText;

    }

    public void setIconCode(String iconCode) {

        this.iconCode = iconCode;

    }

    public void setIconCharacter(String iconCharacter) {

        this.iconCharacter = iconCharacter;

    }

    public void setIconColor(String iconColor) {

        this.iconColor = iconColor;

    }

    public void setIconBgColor(String iconBgColor) {

        this.iconBgColor = iconBgColor;

    }

    public void setOpenNewtabIcon(String openNewtabIcon) {

        this.openNewtabIcon = openNewtabIcon;

    }

    public void setUrlLinkIcon(String urlLinkIcon) {

        this.urlLinkIcon = urlLinkIcon;

    }

My interface:

@ConsumerType

public interface FeaturedIcons {

    /**

     * Returns the list items, the Collection representing the list items.

     *

     * @return the list items

     */

    Collection<IconModel> getListItems();

}

   

My implementation class:

@Model(adaptables = SlingHttpServletRequest.class, adapters = FeaturedIcons.class)

@Exporter(name = Constants.EXPORTER_NAME, extensions = Constants.EXPORTER_EXTENSION)

public class FeaturedIconsImpl extends ButtonModel implements FeaturedIcons {

    private Collection<IconModel> listIcons;

    @ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)

    private String[] listItems;

   

    @PostConstruct

    private void initModel() {

        listIcons = IconsUtil.getListIcons(listItems);

    }

    @Override

    public Collection<IconModel> getListItems() {

        return listIcons;

    }

}

Thanks once more!

Hi,

Please use the following code to get list injected in model:

@Model(adaptables = SlingHttpServletRequest.class, adapters = FeaturedIcons.class)

@Exporter(name = Constants.EXPORTER_NAME, extensions = Constants.EXPORTER_EXTENSION)

public class FeaturedIconsImpl extends ButtonModel implements FeaturedIcons {

    private Collection<IconModel> listIcons;

    @Inject

@Optional

    private String[] listItems;

    @PostConstruct

    private void initModel() {

        listIcons = IconsUtil.getListIcons(listItems);

    }

    @Override

    public Collection<IconModel> getListItems() {

        return listIcons;

    }

}

Regards,
Himanshu
