this is much better than what i just stumbled upon I think then,
correct? Here is what I just did (and it actually worked to my
surprise)....
FacesContext ctx = FacesContext.getCurrentInstance();
ExternalContext extCtx = ctx.getExternalContext();
Map<Object, Object> sessionMap = extCtx.getApplicationMap();
ProjectBean projBean = new ProjectBean();
projBean.setNodeId(nodeId);
projBean.setName("desc="+node.getDescription());
projBean.setDescription("TempDescriptionDean");
sessionMap.put("projectBean", projBean);
I like your way better though! Thank you very much!!!
thanks,

You can get a reference to a managed bean defined in faces-config.xml
this way:
ValueBinding bind =
FacesContext.getCurrentInstance().getApplication()
.createValueBinding("#{myBean}");
MyBean myBean = (MyBean)bind.getValue(this.facesContext);
It can be done too using the variableResolver. El expression can
reference a managed bean or a property (eg. #{myBean.myProperty}. You
can get an set a value.
If myBean doesn't exists, Faces creates a new instance and returns it.

I am not sure I understand. In treeBean, how do I get a
folderBean(that
will be created if it doesn't exist). I was looking at
FacestContext
ExternalContext
I could not find any methods that I can use to look up
"folderBean"(and
create a FolderBean if one doesn't exist), but I suppose I am just
missing this. Could you point me to the method?
LASTLY, can this bean be request scoped in this case then? it sounds
like it to me, but I am a newb in this stuff.
