Javascript conflicts when multiple portlets on same portal..

Hi!,

I'm trying to deploy ops within a couple of portlets that I'm planning to deploy on JBoss Portal. With only one portlet at a time on portal everything seems to be working fine but when I open multiple ops portlets they stop working because of some javascript conflicts.. is there any solution for this?

Thanks in advance.

Those cases are a little hard to reproduce for me because I don't have
JBoss Portal readily installed here. But what is the JavaScript error
you are getting? If you are running Firefox, maybe you have Firebug
running as well, and can give us a JavaScript stack trace for the
exception (if it is not easy to copy and paste in a message, you can
attach a screenshot of the stack trace to your response).

Hey,

theres no javascript error but those portlets just don't function
correctly, for example when I deploy two ops example portlets
(Calculator & Instant Translation) and they are both open at the same
time happens that when using the calculator numbers get duplicated..

The posts and responses with those two portlets  (using calculator) looks
like this:

With only one portlet (the other portlet was minimized), the calculator
works and the post and response look like this:

<!DOCTYPE xxforms:event-request [<!ENTITY nbsp "&#160;">]>
<xxforms:event-request xmlns:xxforms="http://orbeon.org/oxf/xml/xforms">

        <xxforms:event name="DOMActivate"

    </xxforms:action>
</xxforms:event-request>

<?xml version="1.0" encoding="utf-8"?>
<xxf:event-response xmlns:xxf="http://orbeon.org/oxf/xml/xforms">

It looks like the DOMActivate event is duplicated when two Orbeon
portlets are on same page.

Also when the ‘Back to portlet home’ link is clicked in the one portlet,
the status of form fields (for example, the text written to the
translate text field) in the other portlet is cleared.

There is a prefix added to the control IDs when those are in a portal.
But in the code you quote, it is always "jbpd7ee2b55". Can you check
in the source of the generated HTML if that prefix is the different or
the same when you have the same example running in 2 portlets?

I opened two calculator portlets to same portal and both had their own
prefixes  in their control IDs, yet still when using either one the
numbers on its screen got duplicated.. any ideas what might cause this?

So your are saying that if you click on the "1" button in on portlet,
then "1" is displayed in the output area in both portlets?

No, not both but twice in the "calculator screen" of the portlet which
was clicked -> "11". The other calculator portlets screen stays the
same (empty if it was empty..), so in that way it works correctly..

OK, I have never seen this in the past. Sorry but I seem to be running
out of ideas about this one :).

We did some debugging and were able to fix that duplication problem with
the following fix:

// Run xformsPageLoaded when the browser has finished loading the page
// In case this script is loaded twice, we still want to run the
initialization only once
var windowloadlisteners = YAHOO.util.Event.getListeners(window, "load");
if (!windowloadlisteners || windowloadlisteners.length == 0) {
    ORBEON.xforms.Globals.pageLoadedRegistered = true;
    YAHOO.util.Event.addListener(window, "load",
ORBEON.xforms.Init.document);
}

.. there was already a check, in the original script, which tried to
prevent for the listener being added twice but it didn't work properly.
We haven't yet tested this much so it might cause some other problems?

Very nice! Thank you for the fix. You are right, there was already
some code detecting this condition and I think we broke it when we
started using ORBEON.xforms.Globals instead of just global variables.
If xforms.js is included multiple times in the page, then
ORBEON.xforms.Globals will be re-initialized every time, and we won't
be able to detect that the initialization had happened already.

I put in a fix which is slightly different than what you proposed. I
made it so ORBEON.xforms.Globals wouldn't be re-initialized the second
time xforms.js is loaded. The fix is checked in and will be in the
next nightly build. Could you get it and give it a try? Since the
change is only in xforms.js, you can just download a war and replace
the ops*.jar by those in the war.
