Re: UIComponentBase.java - context.getViewRoot() returns null
Hi,
I am not that into myfaces and webflow, so I better ask before creating an
issue. ;)
What exactly should be done by webflow? Should they call
facesContext.setViewRoot(uiViewRoot) too? Wouldn't that be very... JSF-specific?

Betreff: Re: UIComponentBase.java - context.getViewRoot() returns null
Hi
Looking the stack trace provided very carefully, I can see the problem is
not in myfaces, it is on spring class FlowViewStateManager. Take a look at
this three lines:
at
javax.faces.component.UIViewRoot.processRestoreState(UIViewRoot.java:643)
at
org.springframework.faces.webflow.FlowViewStateManager.restoreComponentState(FlowViewStateManager.java:77)
at
org.springframework.faces.webflow.FlowViewStateManager.restoreView(FlowViewStateManager.java:159)
The code related is this:
public UIViewRoot restoreView(FacesContext context, String viewId,
String renderKitId) {
if (!JsfUtils.isFlowRequest()) {
return delegate.restoreView(context, viewId,
renderKitId);
}
UIViewRoot viewRoot = restoreTreeStructure(context, viewId,
renderKitId);
if (viewRoot != null) {
restoreComponentState(context, viewRoot, renderKitId);
}
return viewRoot;
}
What's the problem? well, look this code from myfaces JspStateManagerImpl:
if (state != null) {
Object[] stateArray = (Object[])state;
TreeStructureManager tsm = new TreeStructureManager();
uiViewRoot = tsm.restoreTreeStructure(stateArray[0]);
if (uiViewRoot != null) {
facesContext.setViewRoot (uiViewRoot);
uiViewRoot.processRestoreState(facesContext,
stateArray[1]);
}
}
It is supposed after restore the tree structure, that
facesContext.setViewRoot(uiViewRoot) should be called. Inclusive, in
DefaultFaceletsStateManagementStrategy we do the same too. An issue should
be created against spring web flow.

Hi,
I just saw, that I'm not working with the beta 2 but with the
snapshot.
In
beta 2 the NPW is thrown at line 1038 (in snapshot at line 1041).
The line is:
String renderKitId = context.getViewRoot().getRenderKitId();
And looking at the variables in debugging mode says, that the
viewRoot
is
null. Sorry for the confusion :)
Of course I don't mind to open a JIRA issue :)
PS: I know tomahawk isn't even supposed to work with myfaces 2,
but
in
generally it does. This one here is the only compatibility problem
I
found
(...for now ;) )

Hi,
Unfortunately there is no tomahawk port for MyFaces 2.0
available
yet,
so
this might be a compatibility problem.
I traced the Exception down and found out that it happens,
because
the
RenderKitFactory returns null for the RenderKit here, see the
code
from
UIComponentBase:
String renderKitId =
context.getViewRoot().getRenderKitId();
RenderKitFactory rkf = (RenderKitFactory)
FactoryFinder.getFactory(FactoryFinder.RENDER_KIT_FACTORY);
RenderKit renderKit = rkf.getRenderKit(context,
renderKitId);
Renderer renderer = renderKit.getRenderer(getFamily(),
rendererType);
In the last line renderKit is null and thus we get a NPE.
Do you mind opening a JIRA issue for this? This would be really
great.
Thanks!

Yes, because FlowViewStateManager is not just delegating in this case, it is
saving and restoring by itself, so it is necessary in this case. In the
javadoc of StateManager, the methods restoreTreeStructure and
restoreComponentState now are implementation details, so in jsf 1.2 of upper
restoreView method should be used.

Re: UIComponentBase.java - context.getViewRoot() returns null
Hi Mathias, the tomahawk component is only available for myFaces 1.1 and 1.2 but not for myFaces 2.0. Thus I doubt that tomahawk will work with myfaces 2.0. One just has to wait until a version for Faces 2.0 is available. Andreas.

Re: UIComponentBase.java - context.getViewRoot() returns null
Hi
Looking the stack trace provided very carefully, I can see the problem is
not in myfaces, it is on spring class FlowViewStateManager. Take a look at
this three lines:
at javax.faces.component.UIViewRoot.processRestoreState(UIViewRoot.java:643)
at
org.springframework.faces.webflow.FlowViewStateManager.restoreComponentState(FlowViewStateManager.java:77)
at
org.springframework.faces.webflow.FlowViewStateManager.restoreView(FlowViewStateManager.java:159)
The code related is this:
public UIViewRoot restoreView(FacesContext context, String viewId,
String renderKitId) {
if (!JsfUtils.isFlowRequest()) {
return delegate.restoreView(context, viewId,
renderKitId);
}
UIViewRoot viewRoot = restoreTreeStructure(context, viewId,
renderKitId);
if (viewRoot != null) {
restoreComponentState(context, viewRoot, renderKitId);
}
return viewRoot;
}
What's the problem? well, look this code from myfaces JspStateManagerImpl:
if (state != null) {
Object[] stateArray = (Object[])state;
TreeStructureManager tsm = new TreeStructureManager();
uiViewRoot = tsm.restoreTreeStructure(stateArray[0]);
if (uiViewRoot != null) {
facesContext.setViewRoot (uiViewRoot);
uiViewRoot.processRestoreState(facesContext,
stateArray[1]);
}
}
It is supposed after restore the tree structure, that
facesContext.setViewRoot(uiViewRoot) should be called. Inclusive, in
DefaultFaceletsStateManagementStrategy we do the same too. An issue should
be created against spring web flow.
