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.
thanks,
dean
