Question about extending the screen object
Hi!
On my site I have several screens that I want a certain specific java-coded
behavior for. I see in the documentation that the way to do this is to
create a Super-Screen class and let all my other screens extend that one.
However, if I don't want to implement any other behavior in the screens this
means that I will have several java classes with an empty body, all they do
is extend my Super-Screen.
Is this the way to do it or is there any way around this so I do not need to
create one class for each template?
Or rather, can FooTemplate.vm execute the code in BarClass.class?

This was exactly the answer I was looking for. =)
Thank you very much

Hi Ludwig,
why do you not create to paths?
your.application.modules.screens.alpha.Default.class and
your.application.modules.screens.beta.Default.class
then under src/webapp/templates/screens/alpha you create A.vm, B.vm and C.vm
and under src/webapp/templates/screens/beta you create D.vm, E.vm and F.vm
If you have Functionality you need in both screen classes you go ahead and
create a your.application.modules.screens.Default.class and let
alpha.Default.class and beta.Default.class extend from that.
Will that solve your problems?
Kind regards

RE: Question about extending the screen object
Posted by Ludwig Magnusson <lu...@greenstreetconsulting.se>.
I probably wasn't clear enough...
Let's say I have screens A, B and C and I want them to implement behavior
alpha.
I also have screens D, E and F and I want them to implement behavior beta.
Now, I could create two abstract java screen classes called alpha and beta.
Then I create java classes A - F and I let them extend alpha and beta. This
will work, however I will have 6 classes (A-F) that do not have a body. They
will all look like this:
public class A extends Alpha {
}
public abstract class Alpha extends VelocityScreen {
//Here there will actually be code
}
My question is:
Is this the only way to execute the code in Alpha when a request for A.vm is
made?
The only issue here is that I might end up with 20 or something classes that
look like the A class, and I wonder if that is really necessary.

Allright I think that will solve my problems for now, however what if I want
two sets of screens that have different behavior? Is there a solution for
that?

Hi Ludwig,
create a Default.class Turbine will look for it if it cannot find a screen
Class for a specific Template.
It looks for <Package1>.<subpackage>.<TemplateName>.class
Then for <Package1>.<subpackage>.Default.class
Then for <Package1>.Default.class
And so on.
I hope this made it clear
