fr-set-label for fr:autocomplete in an XBL component

I'm finally getting around to doing the smart thing and moving my autocomplete controls into XBL components to better facilitate repeatability within my form.  The transition is nearly complete (the dynamic itemset is populated based on queries that the user types into the fr:autocomplete text input), but I haven't quite figured out how to set the label of the XBL component when the document reloads in the form.

Before the change to XBL, the code to set the labels looked something like this:

<xforms:action ev:event="xforms-ready">
  <xforms:action xxforms:iterate="//subject">
    <xxforms:variable name="name" select="name()"/>
    <xforms:setindex repeat="{concat($name, '-repeat')}" index="position()"/>
    <xforms:dispatch target="{concat($name, '-autocomplete-control')}" name="fr-set-label">
      <xxforms:context name="label" select="normalize-space(context())"/>
    </xforms:dispatch>
  </xforms:action>
</xforms:action>

This action is defined in the model for my form.  It doesn't successfully set the label of the fr:autocomplete contained in XBL.

In my test form, I am calling the new component with this:

<xforms:repeat nodeset="subject" id="subject-repeat">
  <eaditor:subject-autocomplete ref="."/>
</xforms:repeat>

Attached is the XBL component.  It contains a model, but it seems that <xforms:action ev:event="xforms-ready"> does not work in that model.  Since the above xforms:action does not set the label of the component when embedded into the model in my test form, I'm not quite sure where the problem lies or potential workarounds.

Help would be greatly appreciated,
Ethan

Hi Ethan,

First, xforms-ready is intentionally not supported on models of XBL
components. As you found out, you should use
xforms-model-construct-done in that case (an in general, in most cases
it makes more sense to use xforms-model-construct-done). This is
documented on:

http://wiki.orbeon.com/forms/doc/developer-guide/xbl-components-guide#TOC-Construction-and-destruction-of-loc

Second, you are doing a <xforms:dispatch target="$binding">. The value
of the "target" attribute is expected to be an id (not an XPath
expression returning a node to which a control is bound). So in your
case, if you want to dispatch this to the <fr:autocomplete>, you can
try: <xforms:dispatch target="subject-autocomplete-control">.

You'll let us know how this works for you,

Alex

Ethan,

Yes, xforms-model-construct-done is called in your XBL local model.
And yes, you can dispatch an event to a control inside your XBL
component, referring to that control by id. You need to make sure that
the control in a section of your XBL which is in inner scope
(xxbl:scope="inner"), as your XBL model is always in inner scope.

If this doesn't work, I would setup debugging for development (see
link below, if you don't already have this setup), and look at exactly
what is happening the sequence of events in the log. If your dispatch
has no effect because Orbeon Forms can't find the specified id, the
log will tell you about it.

http://wiki.orbeon.com/forms/doc/developer-guide/xforms-logging#TOC-Development-configuration

And of course, if you have a simple and reproducible case, we can also
look at it, if this can help.

Hi Alex,

I believe I have done this in the way that you have described, so I have included a form.  I can add repeatable subjects and the Solr querying works fine for autocomplete.  It's just that set-label doesn't work on xforms-model-construct-done in my code.

The form queries a server at localhost, but this isn't important as I have already populated a test model with a value to load.

Thanks for your help,
Ethan
