model update failing, I can't see why

[Laurie Harper <la...@holoweb.net>]

I have this really weird problem I can't explain. I'm hoping someone can 
give me some insight. The problem is that my backing bean isn't being 
updated properly during the update model phase, *unless* I include a 
hidden input. With the source listed below it works fine, but if I 
remove the h:inputHidden I get a call to getDescription() instead of 
setDescription().

The action for the h:commandButton fires, but because the model hasn't 
been updated it has no effect. Here's the code:


<h:commandButton value="#{msgs['label.Save']}"
     action="#{backing.save}"/>

<h:inputText id="description"
     value="#{backing.project.description}"
     rendered="#{backing.renderMode eq 'edit'}"/>

<h:inputHidden id="mode" value="edit"
     rendered="#{backing.renderMode eq 'edit'}"/>

<h:outputText
     value="#{backing.project.description}"
     rendered="#{not empty backing.project
                 and backing.renderMode eq 'view'}"/>


As I say, as long as I have that hidden input everything's fine. I have 
an h:messages in my view and it's not showing any conversion or 
validation errors, with or without the hidden input.

I don't understand :-( Any help would be appreciated!
