Motivation

edit

You want to use a selection list to conditionally populate a text area.

<xf:model>
    <xf:instance id="save-data">
       <data xmlns="">
          <message-type>test-message-1</message-type>
          <current-message/>
       </data>
    </xf:instance>
    
    <xf:instance id="code-table">
       <data xmlns="">
          <messages>
             <message type="test-message-1">Message Type 1</message>
             <message type="test-message-2">Message Type 2</message>
             <message type="test-message-3">Message Type 3</message>
          </messages>
       </data>
    </xf:instance>
    
    <xf:bind nodeset="instance('save-data')/current-message"
        calculate="instance('code-table')/messages/message[@type = instance('save-data')/message-type]"/>
    
    <xf:submission id="post-test" method="post" action="echo-post.xq" 
        instance="save-data" replace="all"/>   
      
</xf:model>

<body>
    <p>Enter a message in the text area below and press the "Submit via HTTP POST" button.</p>
    <div class="block-form">
    {$style}

        <xf:select1 ref="message-type" class="message">
            <xf:label>Message Type:</xf:label>
            <xf:item>
               <xf:label>Test Message 1</xf:label>
               <xf:value>test-message-1</xf:value>
            </xf:item>
            <xf:item>
               <xf:label>Test Message 2</xf:label>
               <xf:value>test-message-2</xf:value>
            </xf:item>
            <xf:item>
               <xf:label>Test Message 3</xf:label>
               <xf:value>test-message-3</xf:value>
            </xf:item>
        </xf:select1>
        
        <xf:textarea ref="current-message">
            <xf:label>Message:</xf:label>
        </xf:textarea>
      
    </div>
     <xf:submit submission="post-test">
         <xf:label>Submit via HTTP POST</xf:label>
       </xf:submit>
</body>
