Using VelocityOnlyLayout is there a way to setTitle?
When using VelocityOnlyLayout is there a way to set the title from the
screen template? I used to use $page.setTitle("title unique to screen") in
my screen template but this is only posssible when using VelocityECSLayout.
Now that the title is set in the Default.vm in the layout sub directory
specific to the role of the user eg. ..../app/layout/Admin/Default.vm I need
a way to recognise which screen is being used and to somehow get a title
associated with that screen. Has anybody done this before?

Yes I am creating the page from a Default.java that is common to all my
screens regardless of which sub directory they are in. I am using a pull
tool for all requirements unique to a particular screen.
I suppose I could use the Context in the Default.java to find the template
being used and have a look-up to match that against the title. Or I could
put the title into the Context, but not sure when I have access to the
Context to do this prior to the screen being displayed for the first time?

Just off the top of my head, couldn't you use <title>$myTitle</title> and
then set myTitle in the .java file. Is this how you are creating the page?

The Perl module HTML::Mason has an interesting solution. Their
equivalent of the screen/template can set template properties. The
equivalent of the layout can read those properties before rendering the
content of the template. I like that usage. It lets you keep the
"meta-data" in the template.
I don't know enough about the internals of Velocity to know if this
would be possible, but if the template could set a property in the
context and the layout could get a handle on that context before
velocity renders the template, then the same sort of usage could be
employed here.

This is what we did in scarab, which uses t3. Some sort of meta-data
outside the screen template is needed, at least I have not come up with
a better solution.

Eric,
I had thought about the idea of using a pull tool to somehow extract the
screen template I was using and have a lookup for the title that goes with
it, but not very elegant.
I have added these to my own application properties file.
# -------------------------------------------------------------------
#
# The roles of the users of rwTransformer are shown here
# These are as found in the Turbine_Role table
# They are used to select the layout used
# The roles.directory values must follow the same ordering of roles
# property values
# The values represent the directories under which actions and
# screens the different roles are allowed access to.
# -------------------------------------------------------------------
roles=Administrator, Extract User, Message User
role.directory=Admin, ExtractUser, MsgUser
# -------------------------------------------------------------------
#
# The layouts used for the different user roles
# Property values must be in the same order as the roles above
# -------------------------------------------------------------------
role.layout=/Admin/Default.vm, /ExtractUser/Default.vm, /MsgUser/Default.vm
These are used by my SecureAction and SecureScreen implemetations to
determine the layouts based on role and directories specific to the roles.
I suppose I could add the titles specific to the screens in the properties
file too, but it is not as compact as this as there are few roles in the
system and quite a lot more screens.
regards
David

Now I get it. I think this use case was part of the
ECS debate you mentioned. As you've discovered, you
can only do that with ECS in the picture. I know
you have returned to ECS, but for the sake of the
discussion I want to brainstorm some alternatives.
The first one that leaps to mind is to create a pull
tool for the common elements in your layout, instead
of using the layout. So your screen templates could
use something like this:
$header.renderWithTitle("unique title for this page")
Of course, this doesn't cleanly separate the layout
from the screen:
<table>
<tr><td colspan="2">$header.renderFoo()</td><tr>
<tr><td>$leftBar.renderFoo()<td>
<td>
<!-- your screen goes here -->
</td>
</tr>
</table>
In Turbine 3, I understand the the pipeline is thought
to enable something of this nature, but I haven't even
looked at it, so I can't say how that will work.

Eric,
You are missing the point. I have one layout template,
.../app/layouts/Admin/Default.vm, for 12 screen classes. This enforces
consistency of look and feel for a given role (Admin) using the system.
Having $page.setTitle(..) was very powerful in this context. I see having to
create 12 identical layouts with different names and one difference, that is
title, as being poor architecture.
I have reverted to VelocityECSLayout by solving the problem with not finding
my JavaScript file (don't ask) by extending TemplatePageAttributes to have a
method that allows me to setScript(...) and I am happily using
VelocityECSLayout again after a brief but painful foray into
VelocityOnlyLayout.
Thanks for the suggestion though.
David

Is there some reason that just using the HTML isn't working?
In the VelocityLayout, you don't get to use HTML to control
anything outside the <body> tags. So you have to use $page
in order to set a title. Part of what's interesting about
VelocityOnlyLayout is that you get to include the rest of the
HTML.
try this at the top of your .vm:
<html>
<head><title>title unique to screen</title></head>
<body>
Hope that helps.
