sharing instance

Hi

* how can I share instance b/w pages in ops 3.6 by using the xupdate,

* And how realize navigation with buttons (Xforms:submit or xforms:trigger ..)

I hope have an example

Exple :

   I have page1.xhtml in which i ask the name, and i want to display this name in another page (page2.xhtml), the problem that when i use the function doc('input:instance') the engine return an error (can not load).

   Page 1 :

<xforms:model>
    <xforms:instance xmlns="">
            <xi:include href="input:instance"/>
    </xforms:instance>
</xforms:model>

</head>
<body>
<xforms:group ref="/personne">

    <p>Nom :
             <xforms:input ref="nom" incremental="true">
             </xforms:input>
     </p>
</xforms:group>
</body>
..

Instance :

<personne>
       <nom />
</personne>

Page 2 :

<xforms:model>
    <xforms:instance xmlns="">
            <xi:include href="input:instance"/>
    </xforms:instance>
</xforms:model>

</head>
<body>
<xforms:group ref="/personne">

    <p>Nom :
             <xforms:output ref="doc(input:instance')/nom" >
             </xforms:input>
     </p>
</xforms:group>
</body>
..

Thanks and regards

hi rachid,

I recommend to start with the page flow definition:

http://www.orbeon.com/ops/doc/reference-page-flow#d231e11

You just need two page definitions. These pages don't need a model, just
a view. You may have to adjust the paths to the XHTML pages.

<page id="ask-name"
path-info="/ask-name"
view="pages/test/ask-name.xhtml"/>

<page id="show-name"
path-info="/show-name"
view="pages/test/show-name.xhtml"/>

The ask-name page could look as follows:

<?xml version="1.0" encoding="utf-8"?>
<xhtml:html
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xhtml="http://www.w3.org/1999/xhtml">
<xhtml:head>
<xhtml:title>Ask Name</xhtml:title>
<xforms:model>
<xforms:instance id="instance">
<personne xmlns="">
<nom />
</personne>
</xforms:instance>
<xforms:submission
id="default-submission"
method="post" replace="all"
action="/show-name"
ref="instance('instance')">
</xforms:submission>
</xforms:model>
</xhtml:head>
<xhtml:body>
<xhtml:p>
<xforms:input ref="nom">
<xforms:label>Please enter a name: </xforms:label>
</xforms:input>
</xhtml:p>
<xhtml:p>
<xforms:submit submission="default-submission">
<xforms:label>OK</xforms:label>
</xforms:submit>
</xhtml:p>
</xhtml:body>
</xhtml:html>

Note that you can't initialize the instance with input:instance if you
don't have a input. So i defined the instance directly here.

The submission sends the 'instance' instance to the page defined in the
page flow for the action (path) "show-name". Because there's no model
defined, the submitted instance is passed directly to the view so it's
available there via the instance input of the page show-name.xhtml:

<?xml version="1.0" encoding="utf-8"?>
<xhtml:html
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns:ev="http://www.w3.org/2001/xml-events">
<xhtml:head>
<xhtml:title>Show Name</xhtml:title>
<xforms:model>
<xforms:instance id="instance" src="input:instance"/>
</xforms:model>
</xhtml:head>
<xhtml:body>
<xhtml:p>Hello, <xforms:output ref="nom" /></xhtml:p>
<xhtml:p>
<xforms:trigger>
<xforms:label>Back</xforms:label>
<xforms:load
ev:event="DOMActivate"
resource="/ask-name" />
</xforms:trigger>
</xhtml:p>
</xhtml:body>
</xhtml:html>

Here, the instance is initialized using the src attribute as described here:

http://www.orbeon.com/ops/doc/reference-xforms-ng#xforms-instance-initialization-pfc

To return to the ask-name page, i inserted a simple trigger. Because
there's no data to submit to that page, it's sufficient to simply load
that page.

There's a small but fatal error in the display.xhtml file. Lines 25-27 are:

<xforms:instance xmlns="">
<xforms:instance id="instance" src="input:instance"/>
</xforms:instance>

It should be only

<xforms:instance id="instance" src="input:instance"/>

Then it should work.
