Question of set value when select1 control selected

I would like set some value when select1 control changed or selected.

like this

<xforms:instance id="countries">
  <countries>
    <country>
      <name />
      <district />
    </country>
  </countries>
</xforms:instance>

<xforms:select1 ref="express-address-county">
  <xforms:label>LABEL NAME</xforms:label>
    <xforms:item>
      <xforms:label>CHOOSE</xforms:label>
      <xforms:value />
    </xforms:item>
    <xforms:itemset nodeset="instance('countries')/country">
      <xforms:label ref="name" />
      <xforms:value ref="name" />
      <xforms:setvalue ev:event="xforms-value-changed" ref="instance('purchase-order')/basic-data/express-area" value="./district" />
    </xforms:itemset>
</xforms:select1>

But nothing happen!

It seem like xforms-value-changed event don't activate.

Does another way to set value when drop-down list selected or changed?

Jack,
in your example, the setvalue element is a child of the itemset, but the
itemset doesn't change. Does it work if you place the setvalue element
under the select1 directly? (just a guess, i didn't test it)

Place the setvalue element under the select1 directly is effective.

But I can't figure out which node selected so value attribute is unknown.

Do you know how to figure out which one selected?

<xforms:setvalue ev:event="xforms-value-changed" ref="instance('purchase-order')/basic-data/express-area"

value="?" />

Jack

there may be better ways, but you could use a comparison between the
selected country and the country names node-list as follows:

value="instance('countries')/country[
    name eq instance('???')//express-address-country
]/district"

This should select the 'district' child of the country that's identified
by the selected name.
