Hi

I have a prob with displaying my combo box on the jsp properly.


my actionForm looks something like:
myActionForm{
myCustomDTOList
... other members
}

now this 'myCustomList' is in turn a java.util.List of my DTO objects.
how do I retrieve, say the name and id from the individual DTO's and populate the combo's labelProperty and property values with these ?

is this possible at all ?
some example syintax would be great ..

any help will be appreciated by this Struts newbie..

thanks in advance !

In your JSP, use the <htmlptionsCollection> tag.

Here is a link that tells you how to use the tag.

You can use the <logic:iterate> tag to access the inner collection from within the outer collection - something like this:

<logic:iterate id="innerCollection" name="myForm" property="outerCollection" >
<htmlptionsCollection name="innerCollection" label="description" value="id" />
</logic:iterate>
