Implementing a return navigation in JSF - jsf

Question

I am looking for a JSF coding practice that will allow one page to link to another that, when it completes, will return to the original page. So I have a page viewDoc.xhtml that has this:
<f:metadata>
<f:viewParam name="id" value="#{viewDoc.id}" />
</f:metadata>
( bunch of stuff to show the document indicated by "id" )
<p:button value="Edit Name/Title"
outcome="editnametitle">
<f:param name="id" value="#{param.id}" />
</p:button>
Then I have a page editnametitle.xhtml that has this:
<h:form>
(input fields and stuff)
<p:commandButton value="Save Changes"
action="#{editNameTitle.doSave()}"
/>
<p:commandButton value="Cancel"
action="#{editNameTitle.doCancel()}"
immediate="true"
/>
</h:form>
So how do I implement the backing bean methods doSave() and doCancel() such that when they finish they navigate back to viewDoc.xhtml with the id parameter of the document included?
I haven't found any guidance for a solution and I haven't been happy with any approach I have thought of so far. I have thought of something like adding to the p:button the return path like:
<p:button value="Edit Name/Title"
outcome="editnametitle">
<f:param name="id" value="#{param.id}" />
<f:param name="returnoutcome" value="viewDoc" />
</p:button>
Is this the right approach? Or is there some JSF facility that does this that I missed?

Answer 1

Yes, that's basically it if those requests are idempotent.
One possible improvement is that you can dynamically obtain the current view ID as below:
<f:param name="returnoutcome" value="#{view.viewId}" />
This allows abstracting away it in a reusable custom tag.
Personally I'd use parameter name "from" too as that's more short.
