Greetings Rob, 'cos there is an XPath function to help you, e.g. 
ref="instance('x')/mystuff". The default for instance() is the first one 
in the model in document order.

Regards, Roland

RE: selection="open" attribute on a selectOne element






Greetings Roland,
 
No, I wasn't aware of that. 
 
How then does a submission element refer to an instance; as far as I can 
see the submission has a reference which could be (say) //root. If the 
submission is a child of a model with only one instance, that can only 
point to one node, but what if the model has two instances with //root 
nodes?
 
In fact dipping into the spec at 2.4 "form controls should specify which 
model element contains the instance data to which they bind. This is 
accomplished through a model attribute that is part of the binding 
attributes". Again if the model contains multiple instances, how are the 
bindings to be specified without model= and instance= attributes?
 
Regards
 
Rob

Greetings, if you are using as old a version of the spec as you indicate 
you may not realise that in the latest version you are allowed to have 
multiple instance elements in a single model. So yes, two instances, but 
that no longer requires two models. 

Regards, Roland

Mark, 
  
what is the advantage of using a single model in this scenario. Surely 
allowing the select1 and the itemset to utilise different models permits 
the gathering of data from multiple sources to be serialised for one 
submission? How could that be achieved if the select1 and the itemset have 
to be from one model? 
  
Using different models seems to be supported in FormsPlayer 1, and gives a 
very flexible architecture. 
  
Regards 
  
Rob

Thanks for that - I'll look into changing it to only use one model if I 
can, as I can't see anything else wrong with it.

Carryl, 
  
Wow! I believe that's now a collectors' item ;) 
  
But on your general point, yes @selection="open" should work the way you 
describe. 
  
Mark 
  
PS There is some ambiguity as to whether you should be allowed to use a 
different model on the xf:itemset than on the xf:select1. The consensus at 
the moment is that they should not be from different models, so watch out 
there, too.

Hi Mark, 
  
We are using quite an old implementation - the "Working Draft 18 January 
2002" version, which would explain the use of deprecated tags.  However, 
this version still describes the use of this attribute, so I thought it 
should work! 
  
Cheers, 
Carryl

Carryl, 
  
<selectOne> had its name changed a very long time ago to <select1>, and 
<caption> is now <label> ... so I think the first question is what 
implementation are you using?

Subject: selection="open" attribute on a selectOne element

Hi, 
  
I'm trying to get a field that shows a value pulled from the database, but 
then allows the user to either accept this value, or input a new value - I 
had understood this was possible using the selection="open" attribute on a 
selectOne element, but can't get it to work.  The field displays the value 
pulled from the database, but doesn't allow me to input an alternative 
value. 
  
It could be that I am merely missing some code to handle the input 
correctly, or something else, I'm not sure - see code snippet below: 
  
       <xf:selectOne selectUI="menu" ref="/data/xmit_num" model="pagedata" 
id="LPStoPSXmitNum" selection="open">
       <xf:itemset nodeset="//configset/configitem" 
model="existingconfig">
        <xf:caption ref="lps_to_ps_xmit_num"/>
        <xf:value ref="lps_to_ps_xmit_num"/>
       </xf:itemset>
      </xf:selectOne> 
  
Any and all advice gratefully received!
