Sightly and SlingModel example that searches for commerce products with specific tags in "/etc"

helloworld.html

<ul data-sly-use.directory="org.summit.lab.core.models.ProductDirectory"
    data-sly-list="${directory.results}">
    <li>${item.properties.jcr:title}</li>
</ul>

        map.put("path", "/etc");
        map.put("1_property", "cq:commerceType");
        map.put("1_property.value", "product");
        map.put("2_property", "cq:tags");
        map.put("2_property.value", "geometrixx-outdoors:activity/hiking");
        
        Query query = queryBuilder.createQuery(PredicateGroup.create(map), resourceResolver.adaptTo(Session.class));
        
        results = query.getResult().getHits().iterator();
    }
}

Hi Gabriel,
This is a very useful example and demonstration of how much less code is required with sightly.

Just wondering, in the above example, if there's a simple way to pass the tag parameter (geometrixx-outdoors:activity/hiking) dynamically from html file to the ProductDirectory class.
I got the request object by various ways of injecting but that doesn't seem to be the one containing the request parameters.

I don't want to write it the ajax way around but read some where in the forum that request parameters can't be passed to sling models.
May be some little hack to pass as context parameter or something ?

Thank you for the help!

Robin.
