Hi all,
the Holidays are over, so it's time to integrate my Code for the
Inter-Widget-Communication-**Helper into RAVE.
What i have done so far:
apache-portal-resources -> integrated my custom JavaScript and CSS through
the custom_js.tag and custom_css.tag. This works quite well everytime the
Page loads :)
The Problem is, that i must inject a little piece of Code into EACH Widget
without manipulating the original widget - everytime a iframe gets loaded.
Example:
original Widget:
<html><head><script src="widget_script.js"> ... </head>...</html>
loaded Widget with Code-Injection:
<html><head><script src="widget_script.js"> ... <script src="myscript.js">
... </head>...</html>
Is this possible with RAVE? At this point, I have found nothing in the
sources that would make it possible. I Think the only way is to use a
custom build of wookie that injects the script for me.
The rave-providers -> W3CWidgetRenderer just loads the List of Widgets
from the Wookie-Store and builds the Block for the rave.registerwidget
function (At least I think that).
It would be nice if i can inject the code to all widgets when loading the
page, whether they are OpenSocial or W3C Widgets.
Has anyone suggestions for me?
Is it possible to load a "default feature" for each widget?
I don't believe there is a way to do this at the moment at a Rave level. On
the OpenSocial side I'm sure you could modify one of the shindig core
features that gets loaded with every widget and add your code to that but I
don't know about the Wookie side.
Hi Chris,
i get the things up and working fine for W3C widgets by using a custom
build of wookie.
For Opensocial Gadgets you said, that there should be a way with the
shindig core features that gets loaded with every widget.
Can you explain a litte more about that?
I need to insert my custom JS-File reference to each Gadget and i need
to enable the pubsub-2 feature in each gadget without modifying any
source core of the original gadget.
I tried to use a custom build of shindig which rave but i get security
errors when loading OpenSocial Gadgets:
"Unable to render OpenSocial Gadget: Gadget is not trusted to render in
this container."
Have you any hint for this problem? (Current Shindig Snapshot)
Thanks,
Christian
Thanks,
Christian

Hi all,
i would like to get familar with the RAVE-Development because i will use
it for my master-thesis.
I'll need to extend RAVE for implementing an Inter-Widget-Communication
(IWC) Helper.
That means, i will implement a Training Environment for Widgets which
doesn't Support IWC originally.
-> Widgets without IWC schould after the Training support the IWC with
other Widgets.
(Only during the User-Session. Original Widget should NOT be modified.)
Thanks for your interest in Rave. We are always looking for new ways to
utilize the Rave platform and hope you can share your work with the
community as you go.
For that, i MUST inject some JavaScript Code into each Widget and the
Portal-Page everytime when RAVE loads a Widget from the
Wookie-Widget-Store
or from antother Store (Wookie is first enough).
We have successfully implemented a testing Environment in Apache Wookie
by
injecting some JS-Code.
Now, i want to Integrate a IWC-Training-Environment in RAVE for Mashups.
-> Is it generally possible to inject Code into widgets each time
widgets
gets Displayed?
It is very easy to include custom code in the container (page). All you
really need to do is customize the custom_js.tag file and point to your
custom javascript. This will allow access to that script from the page.
As
for injecting code into the widget, I'm not sure the best way to do that
with Wookie. With OpenSocial gadgets, you could have a custom feature and
reference it from your gadgets.
Its almost exactly the same with Wookie using custom features - there
are some step-by-step instructions here on how to inject JS into Wookie
widgets by creating a new feature spec:
http://incubator.apache.org/**wookie/docs/developer/**features.html<http://incubator.apache.org/wookie/docs/developer/features.html>
That should work without needing to modify anything in Rave.
-> Where must i start to get my Custom Code to get Loaded by RAVE each
Time widgets gets Displayed?
-> Where is my entrypoint to get famililar with the RAVE-Source Code?
(Already followed the instructions on the Webpage, Eclipse is ready to
run
with RAVE).
The Basic Idea is to send Events from the Widgets over OpenAjax pubsub
to
the portal-Page and implement a Training Environment storing the learned
Events and Destinations in RAVE's Database according to the logged-in
user.
As a general note, Rave already supports OpenAjaxHub for IWC. Again,
I'm
not horribly familiar with the W3C widgets (Wookie) but on the OpenSocial
side all you have to do is include the pubsub2 feature in your gadgets
and
pub/sub works like a champ. I suspect you can already do it from the
Wookie
side as well but someone else will have to confirm.
For Wookie its almost the same. Add the following line to your Widget's
config.xml file:
<feature name="http://www.openajax.org/**hub<http://www.openajax.org/hub>
">
... and you can then call "hub.publish" and "hub.subscribe" from your
Widget's javascript.

Tanks for Your Help,
