[jboss-jira] [JBoss JIRA] (WFLY-1816) StringIndexOutOfBoundsException in JSF web-app after commit for WFLY-476

[Frank Langelage (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-1816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12799556#comment-12799556 ] 

Frank Langelage commented on WFLY-1816:
---------------------------------------

I solved the problem for me, but still not totally clear to me, why this problem appeared with the mentioned commit.
I had abstract base classes having the @SessionScoped annotation like these
@SessionScoped
public abstract class SessionBase implements Serializable
{
...
}
and
@ConversationScoped
public abstract class ConversationBase implements Serializable
{
...
}

and then concrete classes with @Named extending the abstract base class but without @...Scoped like

@Named
public class Settings extends SessionBase
{
...
}
or
@Named
public class CostingResults extends ConversationBase
{
...
}
As said this works with 7.20 and 8.0 until this commit.

And then the <to-view-id> nodes of all elements or from top to the needed outcome seem to be determined, not only for the one fitting to the current outcome.
So actions with an outcome having a fixed to-view-id value in faces-config.xml also resulted in this error.

In my case beans were no longer instantiated.
Empty strings seem to be returned by the expressions like <to-view-id>#{settings.start()}</to-view-id> which result in error inside JSF libs.

I solved the problem by moving the Scoped annotation from the base class to the concrete classes. Not nice, but...
