That helps, yes, for navigation components I can definitely see that. My issue
would be that if we had:
Tiles.xml:
<definition name="myLayout" path="/visualComps/myLayout.jsp">
<put name="header" value="/visualComps/header.jsp" />
<put name="search" value="/visualComps/search.jsp" />
<put name="body" value="" />
<put name="footer" value="/visualComps/footer.jsp" />
</definition>
<definition name="/foo.tiles" extends="myLayout">
<put name="body" value="foo.jsp" />
</definition>
I had envisioned that all my controls that were in the actual foo.jsp (and each
subsequent page) would have to use a global navigation rule. Glad to hear that
I can still have:
<navigation-rule>
<from-view-id>/foo.jsp</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/foo-success.jsp</to-view-id>
</navigation-case>
</navigation-rule>
I was envisioning having to do:
<navigation-rule>
<from-view-id>*</from-view-id>
<navigation-case>
<from-outcome>foo-success</from-outcome>
<to-view-id>/foo-success.jsp</to-view-id>
</navigation-case>
</navigation-rule>
This will likely come out in a future mail to the list (I just joined
yesterday), but I'm getting IO errors (Connection Refused) when the Tiles
plugin tries to load /WEB-INF/tiles.xml. I'm going back and trying running the
sample MyFaces-tiles-example app to see if it has the same issue.

Subject: Re: commandButton does not work with Tiles
Neal,
for instance you have navigation.jsp, that uses <h:commandLink
action="showBarPage" ...../> for navigation to other pages inside your app, so
you need faces-config.xml to realize that.
Now let's look at subviews (Tiles is the same, since a tile is embedded inside
a subview).
You have pages like:
-foo.jsp
-bar.jsp
-myPage.jsp
all off the include navigation.jsp as subview (eg.
<f:subview="navi"><jsp:include page="navigation.jsp"/></f:subview>
or with Tiles)
so each of that pages, *show* the navigation
if the foo.jsp is displayed(foo.jsf in browser), the view-id is "foo.jsp"
ok, if your faces-config navigation rule looks like:
<navigation-rule>
<from-view-id>/navigation.jsp</from-view-id>
<navigation-case>
<from-outcome>showBarPage</from-outcome>
<to-view-id>/bar.jsp</to-view-id>
</navigation-case>
</navigation-rule>
that does not work,
but if you have <from-view-id>/foo.jsp</from-view-id>
that will work.
ok, now let's look what happens when bar.jsf (view-id "bar.jsp") is shown in
the browser.
your navigation rules looks now:
<navigation-rule>
<from-view-id>/foo.jsp</from-view-id>
<navigation-case>
<from-outcome>showBarPage</from-outcome>
<to-view-id>/bar.jsp</to-view-id>
</navigation-case>
</navigation-rule>
yes, that doesn't work.
so add an other
<navigation-rule>
<from-view-id>/bar.jsp</from-view-id>
<navigation-case>
<from-outcome>showBarPage</from-outcome>
<to-view-id>/bar.jsp</to-view-id>
</navigation-case>
</navigation-rule>
that works.
Now you have two rules
<navigation-rule>
<from-view-id>/bar.jsp</from-view-id>
<navigation-case>
<from-outcome>showBarPage</from-outcome>
<to-view-id>/bar.jsp</to-view-id>
</navigation-case>
</navigation-rule>
<navigation-rule>
<from-view-id>/foo.jsp</from-view-id>
<navigation-case>
<from-outcome>showBarPage</from-outcome>
<to-view-id>/bar.jsp</to-view-id>
</navigation-case>
</navigation-rule>
A navigation rule like the first we talked about won't work!
Only if you are interessted in viewing navigation.jsp (but navigation.jsp
couldn't be presented since it has no <f:view>, because it is designed to be a
*subview*
However, so instead of having two or more rules for the one navigation rule
(<h:commandLink action="showBarPage" ...../>) from navigation.jsp why not using
*global* one ?
<navigation-rule>
<from-view-id>*</from-view-id>
<navigation-case>
<from-outcome>showBarPage</from-outcome>
<to-view-id>/bar.jsp</to-view-id>
</navigation-case>
</navigation-rule>
I hope it was clear to you :)
