[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1643) Complain when user tries to define the same view-id twice in pages.xml

Ning Zhao commented on JBSEAM-1643:
-----------------------------------

I think the Seam complaint  would be meaningful. A while ago I wrote quite a bit page flow definitions in jPDL prior to using the pages.xml. In jPDL, same view-id can be used multiple times if I specify a different name. For example:

<page name="timeOutPage" view-id="/home.xhtml">
...
</page>

<page name="cancelPage" view-id="/home.xhtml">
...
</page>

Obviously jPDL uses the "name" attribute as semantic id, and the view-id as the physical target. But in pages.xml, view-id is the semantic id.....

So if Seam could make some noisy complain when a developer brings her jPDL habit to the pages.xml, it could be very helpful for debugging.....Thanks!

And thanks to Matt for filing this on JIRA!

Ellen

> If you define two page elements with the same view-id in pages.xml, Seam doesn't complain at all.  This can be confusing.
