Multiple Product Listings
Hello,
I am building an app that has several Product types to list, not at
the same time. So far the application is generic in its handling of
these various objects. When it comes to listing them I would like to
have a custom jwc / html for each Product type. Music has an artist
where as clothing has sizes. So my app may contain a MusicListing.jwc
and a ClothingListing.jwc. Is there a way for me to switch out the
'type' on my component 'productListing'? See below
Joe
<div jwcid="productList" element="div">
<div jwcid="productListing"/>
</div>
<component id="productList" type="Foreach">
<binding name="source" expression="productList" />
<binding name="value" expression="currProduct" />
</component>
<component id="productListing" type="ProductListing">
<binding name="index" expression="components.productList.index"/>
<binding name="product" expression="currProduct"/>
</component>

I should have include a pseudo-condition:
<component id="ifClothing" type="Conditional">
<binding name="condition" condition="product instanceof
your.package.Clothing"/>
</component>

Is this what you're trying to do?
You have a list of products to display, so you iterate the list and
display them
You have different display components because each type needs to be
displayed differently
So, you need to be able to identify what type each product is and use
the correct component for it
It seems to me that you might leverage "instanceof" in your loop. So
you'd end up with something like:
<component id="ifClothing" type="Conditional">
<binding name="condition" condition="...."/>
</component>
<component id="ifMusic" type="Conditional">
<binding name="condition" condition="...."/>
</component>
Then in your html template you'd have:
<span jwcid="ifClothing>
<span jwcid="clothingComponent"/>
</span>
<span jwcid="ifMusic>
<span jwcid="musicComponent"/>
</span>
Does this help?

When your Foreach executes, how does it know which product type is
being listed?
