Facing Issue Using datasource in AEM 6.3

Hey Guys,

Hope you are doing well.

We are migrating from AEM 6.1 to AEM 6.3.

And I noticed that drop down in dialog populating through datasource started giving error in AEM 6.3 as below, which was working fine in AEM 6.1.

Have you guys faced any similar kind of issue. And how to implement datasource to populate drop down in dialog in AEM 6.3.

Any lead will be very helpful.

Thanks,

    It works in AEM 6.3. See:

    This Select field is populated by a DataSource object.

      Thank you Scott. You guys are awesome .

      I am having a component called as datasource which can be authored to populate dynamic number of drop down options wherever used.

      Two points which helped me are:     

      1. The different way of creating DataSource that is below section in Java code

      @SuppressWarnings("unchecked")

      //Creating the Datasource Object for populating the drop-down control.

      DataSource ds = new SimpleDataSource(new TransformIterator(countries.keySet().iterator(), new Transformer() {

      @Override

      //Transforms the input object into output object

      public Object transform(Object o) {

      String country = (String) o;

      //Allocating memory to Map

      ValueMap vm = new ValueMapDecorator(new HashMap<String, Object>());

      //Populate the Map

      vm.put("value", country);

      vm.put("text", countries.get(country));

      return new ValueMapResource(resolver, new ResourceMetadata(), "nt:unstructured", vm);

      }

      }));

      2. At datasource Node in touch dialog, I was putting path of component as the value for the property sling:resourceType, while putting path till .html worked : /apps/db-eccs-wm-pwcc/components/content/datasource/datasource.html.

      Thank you.
