Leonardo Uribe commented on MYFACES-2517:
-----------------------------------------
It is probably a bug. The examples proposed for flash object (see test-webapp
on current20 for this ones) does not consider an example like the one proposed,
because in that moment all stuff related to GET support was not implemented.
Remove the check should work, but anyway I'll take a look at this one.
> Problem with flash and GET
> --------------------------
>
> Key: MYFACES-2517
> URL: https://issues.apache.org/jira/browse/MYFACES-2517
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.0-alpha
> Reporter: Michael Kurz
>
> The flash does not work for GET requests. With the two page fragments below
> the value of the flash is never displayed on navigating between them.
> page1.xhtml:
> <c:set target="#{flash}" property="name" value="Michi (from 1)"/>
> <h:outputText value="#{flash.name}"/>
> <h:link outcome="page2" value="to page2"/>
> page2.xhtml:
> <c:set target="#{flash}" property="name" value="Michi (from 2)"/>
> <h:outputText value="#{flash.name}"/>
> <h:link outcome="page1" value="to page1"/>
> I had a look at FlashImpl and what I did not quite understand was the check
> for isPostback() in doPrePhaseActions(). It is ovious that with this check
> the "old" flash will not be passed over if the request is not a postback.
> When I remove the check everything works as I would expect it.
> What do you guys think, is this a bug or did I miss something?
> Thanks to Ingo Hofmann for making me aware of this behavior.
