Problems binding a collection

[mikehalfsheen]

Hi,
OK I give up, I'm stuck ;(

I have a form command object which has an array (columns). I want to present the values in 'columns' as list of radio buttons. The user then has to select one of the columns. This works fine if they select a radio button, but if they fail to select a value then then I can catch that okt, BUT when the form is redisplayed the column values array is empty. The relevant code I have in the jsp is...

<c:forEach items="${myForm.columns}"
var="column"
varStatus="idx">
<tr>
<td>
<spring:bind path="myForm.columnPos">
<input type="radio" name="columnPos"
value='<c:out value="${idx.index}"/>' />
</spring:bind>
<spring:bind path="myForm.columns[${idx.index}]">
<c:out value="${status.value}"/>
</spring:bind>
</td>
</tr>
</c:forEach>

How do I get the columns array to keep its values if the form submission fails in the formvalidator?

<c:forEach items="${myForm.columns}"
var="column"
varStatus="idx">
<tr>
<td>
<spring:bind path="myForm.columnPos">
<input type="radio" name="columnPos"
value='<c:out value="${idx.index}"/>' />
</spring:bind>
<spring:bind path="myForm.columns[${idx.index}]">

//THIS seems to have done the trick
<input type="hidden" name="columns" value="${status.value}"/>"
//////////////////
<c:out value="${status.value}"/>
</spring:bind>
</td>
</tr>
</c:forEach>
