xforms:select and xforms:insert help needed

Hi List,
I've seen the examples on replacing xforms:copy with a combination of xforms:insert and delete, and this works fine for select1, but I'm having trouble working out a solution using xforms:select.

Below is a simple example of what I have, the first xforms:select is the one I'm working on, the second is the working version using xforms:copy. I know I need to iterate through the values generated by the xforms:select, I'm just not sure how to do this. Essentially for every item populated by the select I need to find the match in the selectTopic instance and insert it into the working instance (metadata). I can do this fine if there is one value, but do not know how to do a loop for all the values in selected.

Thanks for your help.

Efficient solution to inlcude instance data and schema definition from db

Hallo

I am using Orbeon in Portlets. The instance data and schema definition
has to get loaded from a db before the Portlet renders the XForms (using
OrbeonXFormsFilter)

I am quite new with XForms and my first ideas to solve the problem are
not good:
- Parsing the XForms code and replacing the the nodes <xforms:instance>
and <xforms:schema> wont be efficient
- Saving instance data and schema definition as a file to inlcude with
<xforms:instance id="..." src and <xforms:model id="..." schema wont
work because there will be multiple version of that files
- I searched for a suitable listener but didnt find any

Is a any good and efficient solution?

Thank you for your help,
Karolin

I think it is simpler than what you imagine: there is no need to
iterate. The following insert does the trick:

<xforms:insert context="instance('metadata')" nodeset="*" at="last()"
position="after"
origin="instance('selectTopic')/mods:subject/mods:subject[@xlink:href
= tokenize(instance('addTopic')/mods:temp, '\s')]"/>

In instance('addTopic')/mods:temp, you have a space separated list of
URIs. They have been put there by the <xforms:select> based on what
the user selected. Doing a tokenize(instance('addTopic')/mods:temp,
'\s') returns a sequence of strings, and mods:subject[@xlink:href =
tokenize(...)] returns the subjects that have a @xlink:href which is
the same as one of the URI in that sequence. The full source of the
modified file (which runs in the XForms sandbox) is at:
http://pastie.org/655732. I hope this helps,

Nowadays, in most cases we load initial data using an
<xforms:submission>. In essence making an HTTP call to a service which
returns the initial data. If you trigger that call with an
<xforms:send> running on xforms-model-construct-done, this will happen
before the HTML is sent to the browser, and from the browser/user's
perspective, it will be as if the data had been there in-line in the
XForms.
