XInclude of submission element

All,

when I do this:
---------------------
...
    <xforms:submission id="help-submission"
                   ref="instance('rule-instance')"
                   method="get"
                   action="/home" xmlns:xforms="http://www.w3.org/2002/xforms"/>

</xforms:model>


everything works fine.


But when I do this:
---------------------------
...
    <xi:include href="/styling/navigation.home.submission.xml"/>

</xforms:model>


with this content of /styling/navigation.home.submission.xml:
----------------------------------------------------------------------------------------
<xforms:submission id="help-submission"
                   ref="instance('rule-instance')"
                   method="get"
                   action="/home" xmlns:xforms="http://www.w3.org/2002/xforms"/>


clicking on the button gives you this error message from Firefox:
---------------------------------------------------------------------------------------------
"Firefox doesn't know how to open this address, because the protocol
(oxf) isn't associated with any program"


Is this a bug? Sorry for not sending a test case, but I believe you
can reproduce the problem by taking any xforms:submit element, putting
it in another file and xincluding this file.

BTW, I look forward to xpointer support for xinclude in the future. It
would seriously reduce the number of files I need for my templating,
and possibly for my internationalization efforts, as well.

For once, I think not ;-)

What is happening when you use XInclude is that the result of the
inclusion contains an xml:base attribute. There, that xml:base
attribute will be something like:

   xml:base="oxf:/path/to/your/including/file"

The xforms:submission, when resolving the relative action (/home)
actually performs xml:base resolution. This explains why now you are
submitting to an oxf: URI.

To fix this, you can prevent XInclude to generate xml:base, with an
extension attribute:

   <xi:include xxi:omit-xml-base="true" href="..."/>

With xxi mapped as follows:

   xmlns:xxi="http://orbeon.org/oxf/xml/xinclude"

Agreed.

Erik,

Ah, now I understand the xml:base issue. Thanks!
