Question

Run into a bit of an odd problem that is increasingly frustrating

Scenario: I have a list of domain objects, each has a g:select attached to it that is rendered by a remote field.

How do I tie the status variable OR the personInstance ID to the selection box, so that when I use the renderField, I update testDiv_(number)

View:

<g:each in="${listOfPeople}" status="i" var="personInstance">
<td>
    Text: <g:remoteField action="getResults" controller="person" id="" update="testDiv_${personInstance.id}" paramName="search" name="getResults" value="" />
    <g:each in ="${personInstance?.choices}" var="choice" status="x">
        <li>${choice}</li>
    </g:each>
</td>
<td>
    <g:render template="renderThisTemplate"></g:render>
</td>
</g:each>

Template:

<div id="testDiv_${personInstance.id}" class="testDiv_${personInstance.id}">
    <g:select id="aChoice" name="aChoice.id" from="${allChoices}" optionKey="id" value="" />
    <g:actionSubmit action="addChoice" value="Add"/>
</div>

Edit

I know that the remote call (ajax) is passing the update for testDiv_(number). The problem is with the template ID and assigning that value to the template div.

Just incase anyone needs this answer in the future. Apparently you cannot reference the instance variable (personInstance) in the g:each from the template.

So I replaced the g:render with its code and it worked:

<g:each in="${listOfPeople}" status="i" var="personInstance">
<td>
    Text: <g:remoteField action="getResults" controller="person" id="" update="testDiv_${personInstance.id}" paramName="search" name="getResults" value="" />
    <g:each in ="${personInstance?.choices}" var="choice" status="x">
        <li>${choice}</li>
    </g:each>
</td>
<td>
<div id="testDiv_${personInstance.id}" class="testDiv_${personInstance.id}">
    <g:select id="aChoice" name="aChoice.id" from="${allChoices}" optionKey="id" value="" />
    <g:actionSubmit action="addChoice" value="Add"/>
</div>
</td>
</g:each>
