iterate tag problems

Hi all,

I'm iterating over a collection and trying to put the index of the collection as the 
value of a drop down list. It's causing me major headaches!

I have tried both of these approaches:

a)

<html:select name="myForm" property="setMe">
    <logic:iterate id="myInstance" indexId="myIndex" name="myForm" property="myCollection">
        <html:option value="<%=myIndex.intValue()%>">
            <bean:write name="myInstance"/>
        </html:option>
    </logic:iterate>
 </html:select>

b)

<html:select name="myForm" property="setMe">
    <logic:iterate id="myInstance" indexId="myIndex" name="myForm" property="myCollection">
        <html:option value="myIndex">
            <bean:write name="myInstance"/>
        </html:option>
    </logic:iterate>
 </html:select>

neither of these work.

anyone have any idea how to do it?

thanks,
Brian

Thanks Jesse,
I'm getting different errors at least now. :-)

HTTP ERROR: 500 Cannot find bean instance in any scope

using the following code

<html:select name="myForm" property="myProperty">
    <logic:iterate id="instance" indexId="myIndex" name="myForm"
property="myCollection">
        <html:option value='<bean:write name="myIndex"/>'>
            <bean:write name="instance"/>
        </html:option>
    </logic:iterate>
</html:select>

I reckon I might not understand the iterator tag, but I thought you
could give any name to the id parameter. Is this incorrect?
thanks for your help,
Brian

What kind of errors are you getting?


Maybe try using:

<html:option value="<bean:write name="myIndex"/>">


Just a guess.
