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.
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.)
<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
Yes, exactly. We need our renderers. :)
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?
Nope. We need the whole thing (there's some services
registered at the render kit level, for one).
I presume the alternative is to define a render kit for the MyFaces
components I want to use?
I don't think that's the issue here, because we do aggregate
in BASIC_HTML.
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.
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.

Any help appreciated as this is driving me up the wall. Sorry to spam
both groups but I really don't know if my issue is Facelet related or
MyFaces related.
