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.

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. -- Adam On 3/20/06, Murray Brandon <[EMAIL PROTECTED]> wrote: > 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!
