xxforms:variable does not work

It seems that xxforms:variable does not work.
I've tested the example from the documentation and so far, I could not  print the values.

Version: orbeon-PE-3.9rc

XHTML:

<xhtml:head>
    <xforms:model id="my-model">
        <xforms:instance id="my-instance"><form>My-Instance Value</form></xforms:instance>
        <xxforms:variable name="mine" value="'TestValue'"/>
    </xforms:model>
    <xforms:model id="her-model">
        <xforms:instance id="her-instance"><form>Her-Instance Value</form></xforms:instance>
        <xxforms:variable name="hers" value="instance('her-instance')"/>
    </xforms:model>
</xhtml:head>
<xhtml:body>
   
    <xforms:output value="$mine">
        <xforms:label>My stuff:</xforms:label>
    </xforms:output>
    <xforms:group model="her-model">
       
        <xforms:output value="$hers">
            <xforms:label>Her stuff:</xforms:label>
        </xforms:output>
    </xforms:group>
</xhtml:body>

I have checked it and I could print the value using the select attribute:


   <xforms:instance id="resource"><resource>value-1</resource></xforms:instance>       

<xxforms:variable name="variable1" select="instance(resource')"/>
<xforms:output id="control-1" value="$variable1"/>
 

But I should be able to use this variable inside the XPath, and it is not working. I am testing using the following code:

<xforms:instance id="next-resources"><values><value-1><next>value-5</value-1></next></values></xforms:instance>

<xforms:output id="control-2" value="instance('next-resources')/$variable1/next"/>

Hi,

It's unclear to me how you are using the code.

I expect to see something like:

<xxforms:variable name="test" value="instance('my-inst')/pathto/value"/>

   <xforms:output value="$test"/>

Regards,
Hank

Hi, but I have a different situation.

I have the following instances:

<xforms:instance id="resource"><resource>value-1</resource></xforms:instance>       
<xforms:instance id="next-resources"><values><value-1><next>value-5</value-1></next></values></xforms:instance>

I want to get a value from the first instance and use this value inside my xpath expression:

<xxforms:variable name="variable1" select="instance(resource')"/> //Get the value 'value-1', it is working.

<xforms:output id="control-2" value="instance('next-resources')/$variable1/next"/>  //It should print 'value-5'. But it does not work.

I also tried to print using the ref attribute:
<xforms:output id="control-2" reference="instance('next-resources')/$variable1/next"/> // It also does not work.

I found a post about it, but it did not work. I don't know if it's something with this version 3.9 or if it is my mistake.

Hi,

I'm writing from a "klunky" web email program.  Perhaps
I missed the source to your example.

I have use xxforms:variable in xforms:repeat and
other contexts for nodeset an atomic values, so

To "paraphrase,"

  <xforms:output value="instance('value-5"/pathto[thing=$value-1"/>

Of course, output requires an atomic/text value.

Consider posting your code to pastie.org or gist.github.org

Thank you,
Hank

This:

instance('next-resources')/$variable1

doesn't make much sense.

I am going to make a while guess and assume that what you want is:

instance('next-resources')/[name() = $variable1]/next

Thanks a lot Erik!

It was exactly what I wanted :D

The following expression worked:
instance('next-resources')/*[name() = $variable1]/next
