TagManager resolve not working

Hi,

 

I am trying to create a filter component - to filter based on tags. The idea is to pass tags from a specific path to front, so user can choose from dropdown.

I am having an issue, with Tag Manager methods, like resolve.

Code below:

 @Override
    public String getAllTags(){
        Tag tag = null;
        TagManager tagManager = null;
    
        tagManager =  resourceResolver.adaptTo(TagManager.class);
        tag = tagManager.resolveByTitle("Region");
      

        String name = tagManager.getNamespaces()[3].getTitle();
        return tag.getPath();
    }

 

This is just a test method. I know that the return type should be List<Tag>, but for now I just want to get a specific tag path, to understand hot this works. But it is returning null. I know most of the times this issue is related to user permissions, but I already updated the permission to read for content/cq:tags. Thanks!

Hi @AD-Engineer 

 

Please follow the below approach:

 

Create a VO/POJO class with all the desired fields. I added only 2 for DEMO.

public class TagVO {
private String tagName;
private String tagTitle;

public String getTagName() {
return tagName;
}

public void setTagName(String tagName) {
this.tagName = tagName;
}

public String getTagTitle() {
return tagTitle;
}

public void setTagTitle(String tagTitle) {
this.tagTitle = tagTitle;
}
}

 

 Create a Model class and call it in component:

@Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class TestModel {

private static final Logger log = LoggerFactory.getLogger(TestModel.class);

@SlingObject
private ResourceResolver resourceResolver;

private List<TagVO> tagList;

@PostConstruct
protected void init() {
log.info("***** :: Start :: *****");
tagList = new ArrayList<>();
String tagPath = "/content/cq:tags/brands/whatever"; // Here you will pass the parent path to all tags. Ensure anonumous user access is there for this path.
TagManager tagManager = resourceResolver.adaptTo(TagManager.class);
if (tagManager != null) {
Tag tagFromPath = tagManager.resolve(tagPath);
Iterator<Tag> tagIterator = tagFromPath.listChildren();
tagIterator.forEachRemaining(tag -> {
TagVO tagVO = new TagVO();
tagVO.setTagName(tag.getName());
tagVO.setTagTitle(tag.getTitle());
tagList.add(tagVO);
});
}
log.info("***** :: End :: *****");
}

public List<TagVO> getTagList() {
return tagList;
}
}

 

HTL:

<sly data-sly-use.menuobj="com.aem.core.models.TestModel">
<sly data-sly-list.listObj="${menuobj.tagList}">
<li value="${listObj.tagName}">${listObj.tagTitle}</li>
</sly>
</sly>

HTL script can be modified to show as dropdown. I just added as simple list item.

 

Hope this helps!

Thanks
