ParameterNotFoundException when accessing a custom view

Problem(Abstract)

You upgrade to WebSphere Commerce 6.0 where struts are used for views and URLs. When you try to access a custom, view you receive a ParameterNotFoundException.

Symptom The migrated view would appear in the struts-config-migrate.xml similar to the following:
<struts-config>
<global-forwards>
<forward name="MyMigratedView/10001" path="/MyMigratedView.jsp"
className="com.ibm.commerce.struts.ECActionForward">
<set-property property="resourceClassName"
value="com.abc.commands.view.MyMigratedViewCmdImpl"/>
<set-property property="implClassName"
value="com.abc.commands.view.MyMigratedViewCmdImpl" />
<set-property property="interfaceName"
value="com.abc.commands.view.MyMigratedViewCmd"/>
<set-property property="direct" value="true"/>
<set-property property="properties" value="docname=/MyMigratedView.jsp"/>
</forward>
</global-forwards>
<action-mappings>

<action path="/MyMigratedView">
<set-property property="https" value="10001:0"/>
</action>
</action-mappings>
</struts-config>

Invoking the custom view results in an exception such as the following:
