[jira] Created: (PB-7) Messages are not displayed, validation errors are ignored
Messages are not displayed, validation errors are ignored
---------------------------------------------------------
Key: PB-7
URL: http://issues.apache.org/jira/browse/PB-7
Project: Portals Bridges
Type: Bug
Components: jsf
Versions: 0.4
Environment: Jetspeed2
Reporter: Michael Lipp
Priority: Blocker
If the JSF page produces messages (explicitly or implicitly due to validation errors) these messages are not displayed.
Also (and probably related) validation errors are ignored, i.e. the model is changed despite the error.

Hi!
We are currently using a bit brute but working "workaround". It sems to work well for us (we have few jsf pages with dataTable and forms with messages - all seem to work correctly). There are some problems with portlet help mode but I don't mind (messages are more important for me :-)
* Use org.apache.myfaces.portlet.MyFacesGenericPortlet instead of this bridge, i.e. update your portlet.xml to use that class instead of org.apache.portals.bridges.jsf.FacesPortlet.
* Also there is need to make new init-param called default-view (value is same as for ViewPage).
* Last but not least - remove your WEB-INF/lib/portals-bridges-jsf-1.0.jar from web application - they otherwise intercept (?) Jetspeed's PortalContext causing "Unsupporting context exception" in FacesContextFactoryImpl

-------------------------------
This does not solve the issue with request attributes. The FacesContext uses the ExternalContext from the current request to access request attributes and therefore the request attributes are not carried over by simply saving the FacesContext :-(
Note that part of the portlet support of MyFaces has been coded in MyFaces. The MyFaces portlet bridge sets a special flag to indicate the portlet context (only found this after looking very close). Of course, the generic bridge from this (PB) project cannot do this (or only after making sure that the JSF implementation used in the current request is MyFaces).
IMHO, this project will not be able to deliver a generic JSF/portlet bridge without talking to the MyFaces project (and maybe others)!

Michael Lipp commented on PB-7:
-------------------------------
Ronald, where do you think MyFaces creates/saves backing beans with request scope? Right, as MyFaces does not know anything about difficulties with portlet requests, it simply uses the request from the external context.
Before patching the bridge, I spoiled my code with workarounds, saving attributes in session scope and cleaning them after the render phase. But by now I think (and found some confirmation for this on the net) that it is really the bridge's task to carry over the request attributes from the action request to the render request.
Besides, this is completely independant from the portlet-dependant code in MyFaces. I also believe that you can create a generic bridge, but it won't work while the MyFaces implementation has code sections that depend on a flag being set when MyFaces is used in a portlet. Because as long as the bridge does not set this flag, MyFaces will do things that depend on running as a servlet. This dependency is easy to fix in MyFaces if MyFaces can make certain assumptions about the behaviour of the bridge. That's why it won't work unless the two projects start talking to each other (you'll find an issue in MYFACES that I have submitted with a comment that shows that at least some MyFaces developers don't even know about the PB project!).

Hi!
Anyway - later found that even MyFacesGenericPortlet intruduces different but equally weird problems (some fields disappearing on panelGrid on every odd request - looks very mysteriously). So unfortunately my "brute workaround" is no workaround anymore...

Attachment: FacesPortlet.java
We are using the MyFaces portlet bridge in a project being developed. Ran into this problem with FacesMessage objects not being carried over into the render phase. I coded up a solution this problem that works nicely. Saves the messaes on the PortletSession and re-establishes them in the render phase. We would like to see these changes integrated into the project. I have attached the FacesPortlet.java source file with the changes in it.

I see the MyFaces Portlet implementation does not release the FacesContext after handling the ActionRequest, but saves it in the portlet session, and then restores it during the handling of the RenderRequest. This seems like a good solution to this problem.

[ http://issues.apache.org/jira/browse/PB-7?page=comments#action_12357807 ]
Ronald Holshausen commented on PB-7:
------------------------------------
The reason for this behaviour is that the FacesPortlet receives two different responses, and ActionReponse and then a RenderResponse. During the handling of the ActionResponse, validation occurs and the validation messages are added to the FacesContext. However, the context is released after handling the ActionResponse, causing the messages to be discarded, and as the view is only rendered during the handling of the RenderResponse, there are no messages to display.
A fix for this would be to save the messages from the context during the handling of the ActionResponse, and then restore them to the context when handling the RenderResonse.

------------------------------------
I think a generic JSF/portlet bridge can be created, but as long as you don't do funny things with request parameters but rather bind the JSF controls to backing bean properties. Then the request parameters will be decoded and stored in the view and the data model (backing beans) during the handling of the ActionRequest, and as long as the view and context is restored for the RenderRequest (see issue PB-32), the response should be rendered as normal.

Michael Lipp commented on PB-7:
-------------------------------
I have by now learned a lot about the requirements for a Portlet/JSF bridge by tracking down problems and patching the MyFaces bridge until it finally does now what I want.
To summarize, (1) the bridge must carry over request attributes added during action handling to the rendering phase. The portal does not do this, it calls performAction with the ActionRequest and rendering with a RenderRequest and any attributes set on the ActionRequest are lost. JSF does not know about these different requests, it knows only of one request (context) used during the complete cycle. Thus, the bridge must make sure that it looks like this to JSF.
(2) Request attributes set during performAction (i.e. carried over, see above) or during rendering a JSF-portlet must be removed from the request after rendering the JSF-portlet. This is necessary because only one request instance is used for rendering all portlets. (The portlet specification does not require the attributes of this request to be portlet scoped.) Therefore, if the JSF framework or application uses request attributes, there may be unintended interaction between the JSF applications. Neither the JSF framework nor the application is aware of a requirement to "scope" request attributes, because it does not "know" about the application being a portlet and several application being rendered with the same request (two or more JSF-portlets on one page).
