Ricky,
it is possible to do what you wish to do by doing the following (example
taken from a similiar thing that i did):
<logic:iterate id="user" name="myForm" property="users">
<bean:define id="id" property="id" name="user"/>
<html:option value="<%= (String)id %>"><bean:write name="user"
property="username"/></html:option>
</logic:iterate>
here i am iterating through a list of User objects in my form (my User
object is basically a class with the fields 'id' and 'username'). By using
<bean:define..> you can then use a JSP expression to set the value of the
<html:option> using the id of the <bean:define>. So in your case it will be
something like:
<logic:iterate name="authors" id="author">
<bean:define id="an_author" property="author_id" name="author"/>
<html:option value="<%= (String)an_author %>">
<bean:write name="author" property="author_name" />
</html:option>
</logic:iterate>
hope this helps
claire
