Seam 2.3: seam-gen generated project, JBDS reports missing files referenced from view-id in pages.xml

After importing and building a Seam 2.3 seam-gen generated project in JBDS, it reports missing files referenced from view-id in pages.xml and in somEntity.page.xml files.
This works OK for a Seam project created in JBDS and for a Maven project imported to JBDS.

How reproducible:
Import a seam-gen generated EAR project, check pages.xml.

Steps to Reproduce:
1. Create a seam-gen EAR project.
2. Import into JBDS.
3. Open pages.xml, make a change (to trigger build).

Actual results:
On lines referencing a view-id, like
<redirect view-id="/home.xhtml"/>
JBDS shows an error saying:
Cannot find target resource: "/home.xhtml"
