Exadel not using EFS properly - creates errors not finding linked resources with struts-config

ExadelStudio appears to bypass the Eclipse file system (at least when validating the struts-config) so as to not find link resources.

I setup /StrutsHello/WebContent/pages/greeting.jsp to be a linked resource
<link>
<name>WebContent/pages/greeting.jsp</name>
<type>1</type>
<location>C:/dev/tmp/greeting.jsp</location>
</link>

This file is referenced in my struts-config like this
<forward name="sayHello" path="/pages/greeting.jsp"/>

ExadelStudio marks that with an error "Forward sayHello of Action /greeting path attribute reference to non-existent page"

This is incocorrect, this file is there, albeit a linked resource. When I run the webapp in Eclipse+Exadel, the page does work as it should - so WST or something must be using the EFS properly unlike the part of Exadel validating the struts-config.
