Hello, I'm wanting to override the presentation of a Subclass's content (via 
ui:instance) by passing an object/uri/variable from its Parent Class, and 
return some content back to the Parent Class.
I don't know enough about the methods and functions I can use to accomplish 
this.

Discussion:
I have a WebApp.
On my main Class (ParentClass), I'm creating my HTML, and iterating through the 
SPARQL results and building a table to display the Results.
I'm using a ui:ForEach to manage the flow.

?this is the Parent Object
? this has Subclasses : ?Attribute(s)


For each ?attribute, call its class definition, and build the presentation.

Question: From a parent Class, how do I call a particular ui:instance on a 
subclass, pass it an Object/URI/string value. Process the content, and return 
some content?

Example: Parent Class:
            <ui:forEach ui:resultSet="{#
                    SELECT ?attribute
                    WHERE {
                        ?this smart:hasAttribute ?attribute .
                        ?attribute smart:name ?attributeName .
                        ?attribute smart:displayName ?attributeDisaplayName .

                    } }">
                <tr>
                    <td> Call the SubClass  and Return Formatted HTML </td>
                </tr>
            </ui:forEach>

Example SubClass ui:instanceView
<div>
<table name="subclass Details">
        <tr>
            <td>Attribute Name</td>
<td></td>
            <td>Values</td>
        </tr>
        <ui:forEach ui:resultSet="{#
                SELECT ?attributeDisplayName ?attributeName
                WHERE {
                    ? attribute smart:displayName ?attributeDisplayName .
                    ? attribute smart:name ?attributeName .
                } }">
            <tr>
                <td>{= ?attributeName }</td>
            <td> : </td>
                <td>{= ?attributeDisplayName }</td>
            </tr>
        </ui:forEach>
    </table>
</div>

Thanks,
Rocky
