Hello All,
As i was studying the ecommerce application. I found that in
CatalogScreens.xml file the 'category' screen is including one screen
'category-include' and 'category-include' screen is just checking a
condition and including 'categorydetail' screen and in fail widget just a
short message.
I think all this can be done without 'category-include' screen, but there
might be some standards for doing this process. I want to know why these
standards are made.
For ready refernce here is the code for the same :
<screen name="category">
<section>
<actions>
<set field="leftbarScreenName" value="leftbar"/>
<set field="rightbarScreenName" value="rightbar"/>
<set field="MainColumnStyle" value="center"/>
<set field="titleProperty" value="PageTitleCategoryPage"/>
<script
location="component://order/webapp/ordermgr/WEB-INF/actions/entry/catalog/Category.groovy"/>
</actions>
<widgets>
<decorator-screen name="main-decorator"
location="${parameters.mainDecoratorLocation}">
<decorator-section name="body">
<include-screen name="breadcrumbs"/>
<include-screen name="category-include"/>
</decorator-section>
</decorator-screen>
</widgets>
</section>
</screen>
<screen name="category-include">
<section>
<widgets>
<section>
<condition>
<not><if-empty field-name="productCategory"/></not>
</condition>
<widgets>
<include-screen name="${detailScreen}"/>
</widgets>
<fail-widgets>
<label
style="head2">${uiLabelMap.ProductCategoryNotFoundforCategoryID}
${productCategoryId}!</label>
</fail-widgets>
</section>
</widgets>
</section>
</screen>
<screen name="categorydetail">
<section>
<actions>
<set field="productsummaryScreen"
value="component://ecommerce/widget/CatalogScreens.xml#productsummary"/>
<set field="productCategoryLinkScreen"
value="component://ecommerce/widget/CatalogScreens.xml#ProductCategoryLink"/>
<script
location="component://order/webapp/ordermgr/WEB-INF/actions/entry/catalog/CategoryDetail.groovy"/>
<entity-and entity-name="ProductCategoryLink"
list-name="productCategoryLinks" use-cache="true" filter-by-date="true">
<field-map field-name="productCategoryId"
env-name="productCategoryId"/>
<order-by field-name="sequenceNum"/>
</entity-and>
</actions>
<widgets>
<platform-specific><html><html-template
location="component://order/webapp/ordermgr/entry/catalog/categorydetail.ftl"/></html></platform-specific>
</widgets>
</section>
</screen>
Any pointer will be highly appreciated.
