java.lang.NullPointerException during render phase when using ADF and MyFaces Tomahwak components together
Apologies if this topic has been done to death in the group as I've just
joined.
I'm sure it's something to do with my configuration of web.xml or
faces-config.xml, but what?
Either the AdfRenderingContext isn't attached to the thread or
getProperties() is returning null.
I'm using the dump of ADF attached to the myfaces site (ie.
adf-faces-impl-ea20-SNAPSHOT).
I don't think it is trying to render any of the ADF tags (same null
pointer if I comment out the ADF tags),
this is on render of tomahawk/myfaces tags.
Any help appreciated!
Regards, Murray

AW: java.lang.NullPointerException during render phase when using ADF and
MyFaces Tomahwak components together
Posted by Marcel Soulier <ma...@opitz-consulting.de>.
Hi Adam,
sorry that it took me 2 days to reply but I was working on a different project.
Using JSP and MyFaces is kind of a historical thing. I started with JSP and Struts, added Tiles, replaced Struts with MyFaces and now added ADF.
Facelets is something I haven't tried yet.
About the ClassCastException I had:
Right now I can't reproduce it anymore. Might be something else I changed in my application.
But anyway, if the signature of the method "protected final void setProperties(UIComponent component)" allows a UIComponent, I would expect that any casting to UIXComponent would make sure if this is possible first.

Re: java.lang.NullPointerException during render phase when using
ADF and MyFaces Tomahwak components together
Posted by Matt Tyson <ma...@gmail.com>.
I'm seeing this issue using ADF 10.1.3. I have the default renderer set to
adf's renderer, and when I try to render a t:commandlink inside a facet, I
see the following trace:

Looks like the adf renderer needs a faces context that isn't there.

Exactly where was this NullPointerException? We automatically incorporate
all the BASIC_HTML renderkit renderers, which is where the tomahawk
and myfaces renderers go. What I can imagine is that our override of
<h:form> rendering is perhaps causing problems... (We override h:form
to get client-side validation and partial-page rendering working.)

Yes, exactly. We need our renderers. :)

Nope. We need the whole thing (there's some services
registered at the render kit level, for one).

I don't think that's the issue here, because we do aggregate
in BASIC_HTML.

Not needed for runtime - mock is just for testing, build
is for building.
The exception listed below seems like an entirely Facelets
issue (doesn't seem ADF or MyFaces related.) *seems*, but
maybe isn't.

RE: java.lang.NullPointerException during render phase when using ADF and MyFaces Tomahwak components together
Posted by Murray Brandon <mu...@hotmagna.com>.
Partially solved:
The problem is if you define adf core render kit as the default default
render kit, some of the tomahawk/myfaces/facelets components have no
rendering context (not sure which component, cos the exception helpfully
does not tell me), hence the null pointer.
<application>
<default-render-kit-id>
oracle.adf.core
</default-render-kit-id>
</application>
However, if I don't define oracle.adf.core as the default render kit, I
get real ADF components in the component tree but they don't render:
eg. component is:
oracle.adf.view.faces.component.core.input.CoreChooseDate,
renderer=oracle.adf.Date toString=CoreChooseDate[UINodeFacesBean,
id=idp1]
The error is:
Mar 23, 2006 11:36:12 PM
oracle.adf.view.faces.component.UIXComponentBase _getRendererImpl
WARNING: Could not find renderer for
CoreChooseDate[UINodeFacesBean, id=idp1], rendererType = oracle.adf.Date
I commented out the facelets view handler in faces-config.xml and added
the following to web.xml
(I can't seem to see the url http://tinyurl.com/dac6y for the example
web.xml)
<context-param>
<param-name>oracle.adf.view.faces.ALTERNATE_VIEW_HANDLER</param-name>
<param-value>com.sun.facelets.FaceletViewHandler</param-value>
</context-param>
Can I define the ADF render kit just for the ADF components I want to
use?
I presume the alternative is to define a render kit for the MyFaces
components I want to use?
I tried adding some code below to faces-config.xml but it made no
difference to the render.
<render-kit>
<render-kit-id>oracle.adf.core</render-kit-id>
<renderer>
<component-family>oracle.adf.Output</component-family>

Also, if I have the ADF jars in my WEB-INF/lib folder in the tree, I
get:
java.lang.IllegalStateException: Duplicate id : _id0. Child could not be
added.
The ADF jars are below:
adf-faces-api-ea20-SNAPSHOT.jar
adf-faces-api-ea20-SNAPSHOT-mock.jar
adf-faces-build-ea20-SNAPSHOT.jar
adf-faces-impl-ea20-SNAPSHOT.jar
Not exactly sure what the mock and build ones are for, but I left them
in the .war anyway.

MyFaces related.

AW: java.lang.NullPointerException during render phase when using ADF and
MyFaces Tomahwak components together
Posted by Marcel Soulier <ma...@opitz-consulting.de>.
Hi,
so far I have only used MyFaces and currently I am trying to use the ADF-Faces Components with it.
The impression I had about using Tiles with ADF and MyFaces was that I should use the Tiles Servlet because ADF uses its own ViewHandler which would collide with the MyFaces JspTilesViewHandler I used before.
When I was reading Adam's way of setting an alternate ViewHandler in a context-param I had the idea of using the MyFaces JspTilesViewHandlerImpl in a similar way for my JSP-based application.
It works quite well though I encountered a ClassCastException in the UIXComponentTag class where a UIXComponent is needed in the setProperties Method. So I put an "if(component instanceof UIXComponent)" inside this Method and it worked.
Now the reason for this posting is this:
Am I going in the right direction here? Are there any side-effects with using the MyFaces ViewHandler inside an ADF context?
Or maybe there is a different way of getting the advantages of the MyFacesViewHandler (e.g. direct usage of tiles-definitions in navigation rules)?
Maybe anyone here has already used the combination of JSPs, MyFaces, Tiles, ADF and can give some advice.

Murray,
You need to install the FaceletViewHandler using:
<context-param>
<param-name>oracle.adf.view.faces.ALTERNATE_VIEW_HANDLER</param-name>
<param-value>com.sun.facelets.FaceletViewHandler</param-value>
</context-param>
in WEB-INF/web.xml, not in faces-config.xml.
Also, not that it's related to this issue, you need to install the ADF Faces
Filter. Check out the config posted in the other thread for all the details.

Anyone got a working ADF + MyFaces Tomahwak setup?
Posted by Murray Brandon <mu...@hotmagna.com>.
If so, can you please shoot me a copy of your web.xml and
faces-config.xml files?
Thanks!
