A slight afterthought...
My idea of MVC is that the only the View deals with appearance,
although may need a certain amount of logic to handle this. The
Controller carries the business logic and shouldn't be concerned
with appearance, though has to handle I/O of data to the View.
For example, the Controller can tell the View that it wants to
display something as "On" or "Off", but doesn't care how this is done.
The View could display this as verbal "On" or "Off", or could use
icons for red & green traffic lights.
The View should contain all "ViewLogic" necessary to create this
appearance. A useful encapsulation which allows that to be changed
later without affecting the Controller.
I was hoping to handle the View entirely in .html + .wod, so if
the .css changes I just change the references in there. However,
the .wod logic won't cope with that,
No, not as you outlined it. But I think you are trying to do it
wrong. You _can_ do something like
...
class = application.properties.cssClassFor.inputForm.
...
With a bit of support code in Application. This assumes that you
have a properties file with entries like
inputForm = MyInputFormClass;
so I have to extend the View to include a chunk of Java code.
Still MVC as long as I separate it from the Controller code.
However, I'm stuck with the WOComponent being part of the View, and
also the Controller due to pageWithName. Javascript isn't an
option as our client has it turned off for security policies.
Just extra the pageWIth Name calls to another object, say
PageFlowController. Then do
nextPage = mySession.pageFlowController().nextPageFrom(this);
I suppose it's just the nature of webapps that the "Page" is both
View and Controller, though it's good to separate these code-wise.
WO makes a good attempt at this, as long as the View logic doesn't
go beyond boolean.
Not the nature, just the path of least resistance.
