5:06 p.m.
Just upgraded to the 1.17 RC1 release.
Prior to the update, we had the following page defined in a pageflow file:
| <page name="login" view-id="/login.xhtml">
| <redirect/>
| <transition name="cancel" to="info" />
| <transition name="login" to="isLoggedIn">
| <action expression="#{identity.login}"/>
| </transition>
| <transition name="cancel" to="cancelpage" />
| </page>
|
This worked just fine.
However, after the Seam upgrade, we now get the following error after providing the userid
and password and clicking on the button that triggers the login transition in the above
page flow:

I looked at 1.1.7 related posts and could not find anything similar.
Any idea what the problem or solution is?
Thanks!
