Actually, I am trying to get and show all tagging values as a dropdown list in the dialog so that the author can choose the value from the dropdown list. I wrote the code but I am able to get only one tagging value by giving the array number. I have given my code below. Kindly help me to achieve the dropdown list.
package com.project.core.models.impl;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import org.apache.commons.lang3.StringUtils;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.Optional;
import org.apache.sling.models.annotations.injectorspecific.InjectionStrategy;
import org.apache.sling.models.annotations.injectorspecific.Self;
import org.apache.sling.models.annotations.injectorspecific.SlingObject;
import org.apache.sling.models.annotations.injectorspecific.ValueMapValue;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.day.cq.tagging.Tag;
import com.day.cq.tagging.TagManager;
import com.project.core.models.PlanCards;
@Model(adaptables = {Resource.class, SlingHttpServletRequest.class},
adapters = { PlanCards.class},
resourceType = {PlanCardsImpl.RESOURCE_TYPE})
public class PlanCardsImpl implements PlanCards {
private static final Logger LOG = LoggerFactory.getLogger(PlanCardsImpl.class);
/**
* The resource type.
*/
protected static final String RESOURCE_TYPE = "project/components/nwt/slider";
@SlingObject
@Deleted Account
private Resource currentRes;
@Deleted Account
@Deleted Account
private SlingHttpServletRequest request;
@SlingObject
private ResourceResolver resourceResolver;
@ValueMapValue(injectionStrategy = InjectionStrategy.OPTIONAL)
private String dataUses;
@Override
public String getDataUses() {
return dataUses;
}
public void setDataUses(String dataUses) {
this.dataUses = dataUses;
}
@PostConstruct
protected void init() {
String plancardTag = "/content/cq:tags/project/plan-cards/data-uses";
LOG.info("int() --> Plan cards default value");
final TagManager tagManager = currentRes.getResourceResolver().adaptTo(TagManager.class);
final List<String> filterTagList = new ArrayList<>();
LOG.info("Product Details Filter tag path:: {}", plancardTag);
if (StringUtils.isNotBlank(plancardTag)) {
final Tag tag = tagManager.resolve(plancardTag);
if (null != tag) {
tag.listChildren().forEachRemaining(childtag -> {
filterTagList.add(childtag.getTitle());
LOG.info("childtag.getName():: {}", childtag.getName());
});
}
}
LOG.info("filterTagList:: {}", filterTagList.toString());
if (StringUtils.isBlank(dataUses)) {
this.dataUses = filterTagList.get(1);
}
}
}
Solved! Go to Solution.

Hi @Ameen_Dev ,
Please check out this article - https://unlocklearning.in/dynamic-dropdown-in-aem/
It explains all possible ways to develop a Dynamic Dropdown on AEM Dialog.
In section 4(AEM Tags value in Dynamic Selection Dropdown) of the article, You can see the process to use AEM Tags in the dialog dropdown. In your case just need to do some modifications as below.
Hope this would help you !!!

Shiv
This code seems to be fine, and filterTagList object should have a list of Tags.
I am not clear about the purpose of dataUses string object. Ideally, you should have filterTagList as a class variable and should have a getter to return this list.
Now, all you need to do is to create a data source [1], and call your class from the data source.

My apology! I am new to Java so can you please edit the code like what you said, so that I can understand in a better way.

@Shiv_Prakash_Patel Thank you so much. It works as expected but the only problem is it allows multiple selections in the dropdown list. I tried to limit that to just one value but it's not happening.
Hi @Ameen_Dev ,
That's great it works for you !!!
Update multiple boolean to false at select node in cq:dialog, It will allow you only a single selection.
multiple="{Boolean}false"

Shiv
Thanks @Shiv_Prakash_Patel
Can I use the bin in the servlet path?
@Component(service = Servlet.class, property = {Constants.SERVICE_DESCRIPTION + "= Tags value in dynamic Dropdown", "sling.servlet.paths=" + "/bin/cardTagLists", "sling.servlet.methods=" + HttpConstants.METHOD_GET })
Does it have any issues? Or if I need to change the path, which path do you prefer?
