itemset AND item ?

Hi there,

is it valid to combine an itemset and another item tag inside one
select1 control?
<xforms:select1>
<item>
<label>no choice</label>
<value/>
</item>
<itemset ...
...
</itemset>
</xforms:select1>
The xforms spex doesn't mention it, afaik. What I really want is a "no
choice"
item for my select1 control before i fill all the valid items using an
itemset.
Maybe there is a best practise to do just that. Has anybody found out
the best way
to do that?
thanks for any help

Re: itemset AND item ?

It works for me (using XForms classic engine):

<xforms:select1 ref="../move-detail-into" appearance="minimal">
<xforms:item>
<xforms:label>select</xforms:label>
<xforms:value>no-cart</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>new</xforms:label>
<xforms:value>new-carton</xforms:value>
</xforms:item>
<xforms:itemset nodeset="../form-model/cartons/carton">
<xforms:label ref="@id"/>
<xforms:copy ref="@id"/>
</xforms:itemset>
</xforms:select1>

Yes, you can do that. The spec implicitly allows this through the XForms
schema, and it works with OPS, one use case being exactly the purpose
you are mentioning.

Re: itemset AND item ?

I am having problems with that under xforms NG.

I played around with a sample and found out, that the itemset only works, if both
the element bound to the control and the itemset have no namespace.
Any other case (namespace on either or both of the later elements)
leads to either an empty list or an (validation?) error (! - sign shows up).
I wonder if this is right or not. I couldn't find anything about namespaces
in the xforms spex regarding the select or itemset.

In my page though I have the case, that the manual item just doesn't show up, if the
itemset has any entries. I only see the later.
I am still trying to find the source for that, but my page is rather
complex, so it is hard to debug. I am very sure, that both the itemset instance and the
bound instance have no namespaces. Unfortunately there are no error messages in the log.

Maybe you have some more details regarding the namespaces issue Eric? Or maybe
eben just a hint where to look / debug. Is it worth taking a look at the xforms sources
and maybe switch on a debug switch?

Olivier,

Yes, it's a namespace issue, but a user issue ;-)

I explain. Here:

<xforms:instance id="main-no-ns" xmlns="">
<test>
<choice test=""/>
</test>
</xforms:instance>

elements <test> and <choice> are in no namespace. But here:

<xforms:instance id="main-ns" xmlns="www.test-me.org">
<test>
<choice test=""/>
</test>
</xforms:instance>

elements <test> and <choice> are in the "www.test-me.org" namespace.

If you want to address, with XPath, the <choice> element in the first
case, you can write:

instance('main-no-ns')/choice

But, in the second case, you can't just do that. You have to use
prefixes in your XPath expressions in order to make it clear that the
element is in a namespace, e.g.:

instance('main-no-ns')/test-me:choice

Where the prefix "test-me" has been bound to the namespace URI, for
example on the root element of the document, as follows:

xmlns:test-me="www.test-me.org"

I hope this helps! A attach a modified version of your example in the
other thread.
