Bug in the <xforms:load> action

Hi,


The <xforms:load> action does not work with other events than DOMActivate.
At least it does not work with the ev:event="xforms-ready" when placed
within the <xforms:model> (tried to implement meta refresh functionality
using XForms).

Attached is a simple form for testing the functionality. The form
works fine with Mozilla XForms so the syntax ought to be correct. I am
using Orbeon Forms 3.6.0.200712181809.

Regards

This is probably a browser popup blocker, rather than a bug in orbeon. I don't think there is a way around this

Well, I still think it's a bug :) Or can you give me a reasonable
explanation why the same action works when used with the DOMActivate event
but doesn't when used with the xforms-ready event. Or howcome the form
works fine when I am using Mozilla XForms as an XForms implementation but
it doesn't when I am using Orbeon Forms. In both cases, I am using the
same browser, Firefox 2.0.0.16.

Well popup blockers detect the changing on pages on any events other than clicking a link, such as a DOMActivate. Seeing as both browser and xforms implementation are written by Mozilla its likely they have purposely built the application to ignore it, whereas FF sees orbeon as just another webpage...try turning off any popup blockers within FF or that you have installed and see if it works, that should decide if it is a bug within orbeon or an oversensitive popup blocker ;-)

Well that was a very convincing explanation. I disabled the pop-up blocker
from Firefox by following the instructions available at:
http://support.cox.com/sdccommon/asp/contentredirect.asp?sprt_cid=f7c32e32-5ce1-4756-932e-e84465effb96

However, this did not change a thing and the <xforms:load ...
ev:event="xforms-ready" /> (refresh/redirect) still doesn't work with
Orbeon Forms.

Did you try it out? Did you managed to get the form work by turning off
the pop-up blocker?

Regards

I didn't try it, I just made the assumption that this would be the root cause as it has been in the past, I think your right this probably is a bug

Exactly, this is not supported at this point. It has never been
supported so was marked as "RFE". The classification is arguable :),
but the bottom line is that this would need to be implemented.

Do you suggest any work around for accomplishing the same result as in
the sample form i.e. redirecting the user to another web page using XForms
syntax only?

I tried to accomplish the functionality using a couple of different ways.
Unfortunately, only one of them worked but it's pretty ugly hack.
------------------------- 8< ----------------------
[...]
<head>
   <title>XForms - Refresh 3</title>
   <xforms:model>
     <xforms:instance id="temp">
       <temp xmlns="" />
     </xforms:instance>
     <xforms:setfocus control="my-hidden-input" ev:event="xforms-ready" />
   </xforms:model>
   <style type="text/css">
     .hidden {
       visibility: hidden;
     }
   </style>
</head>
<body>
   <h1>XForms - Refresh 3</h1>
   <p class="hidden">
     <xforms:input id="my-hidden-input" ref="instance( 'temp' )">
       <xforms:load resource="http://www.orbeon.com" show="replace"
ev:event="DOMFocusIn" />
     </xforms:input>
   </p>
</body>
[...]
---------------------------- 8< ---------------------

As you can see, I set focus to a hidden input control which then activates
the <xforms:load> action. If I use display: none; the form does not work.


Here is another one (really simple) that I tried out but it didn't work
with Orbeon Forms either (works with Mozilla XForms).
--------------------------- 8< ------------------------
[...]
<xforms:model id="my-model">
   <xforms:load resource="http://www.orbeon.com" show="replace"
ev:event="my-refresh-event" />
   <xforms:dispatch name="my-refresh-event" target="my-model"
ev:event="xforms-ready" />
</xforms:model>
[...]
-------------------------- 8< --------------------------

Okay... here is the version of the Orbeon Forms redirector hack that I am
using at the moment, if somebody is interested.

Ps. CSS in the code can be left out. It's there just as a precaution.

I have done this in the past with some JavaScript, using
YAHOO.util.Event.onDOMReady(your function), where "your function"
calls ORBEON.xforms.Document.dispatchEvent() to dispatch an XForms
event.

Thanks for your suggestion. However, I am looking for pure XForms 1.1
compatible solution. Is there any better way than the one I am using
at the moment?

Other possible, but not pure XForms 1.1 compatible, solutions would be
implementing the functionality using JavaScript or the <meta> tag.

Regards

The best thing to do would be to add support for xforms:load upon page  
initialization. Other than that, I don't see a workaround in pure  
XForms.

Erik, thanks for your answer. Is this feature going to be available in the
next stable release (3.7.0) of Orbeon Forms?

It depends when 3.7 comes out, but given our workload at the moment, I  
would say most likely not since our plan for 3.7 is just to close a  
few blockers, not to implement new features (unless they are needed  
for current projects we are working on).
