Hello Magnolians!
We're looking at writing a couple of modules/extensions for Magnolia - nothing
really CMS related, more things to interface with our customer's existing IT.
To avoid having to rewrite everything in a few months for magnolia 5, we would
like to implement the GUIs in Vaadin from the start.
The question is: how?
I've looked at Vaadin, done some tutorials, and have my GUI working outside of
Magnolia.
I've looked at the new magnolia-module-admincentral-vaadin.
So I have 2 Questions:
1) What's the right way to integrate new Vaadin-based GUI components?
What I'm doing would have been implemented as a "page" in the old adminCentral.
Am I correct in assuming that I would extend
info.magnolia.module.admincentral.components.MagnoliaBaseComponent to create
my gui-component, and then simply configure a menu-item with
view=myviewclassname to provide access to my view from adminCentral's menu?
Do I need to do any special magnolia-related init() or cleanup work in the
Vaadin component?
2) I don't want to run the experimental Vaadin-AdminCentral in production
yet. Can I use Vaadin from within the old adminCentral?
My problem is that I don't want to run Vaadin-Admincentral in production at the
moment, it's not ready. I'd still like to offer my vaadin-based GUI.
I see the MagnoliaBaseComponent class depends upon prior initialization of the
AdminCentralVaadinApplication class, and uses the application's layout
("mainComponent").
I think one approach might be to directly extend CustomComponent for the
moment, and use my own Vaadin Application class for the moment. By initializing
it similarily to AdminCentralVaadinApplication I should be able to use the
existing magnolia-vaadin-theme.
Changing the class to extend MagnoliaBaseComponent should then be fairly easy
when Magnolia 5.0 comes.
Now one question remains: how add the Vaadin Servlet to the old adminCentral -
would it be sufficient to create a new servlet mapping under
config->filters->servlets, say mapped to the URI "/.magnolia/vaadinpreview/*" ?
Thanks for your thoughts and feedback!
Regards from Vienna,
Richard
