IIRC, logic:iterate also only supports this notation in the "property"
attribute, not in the name attribute (as all tags do)

You can also use the bean:define tag, that should do the trick in your
case:
<html:select property="userId">
<bean:define
id="coll"
name="database"
property="usersTable.users">
<html:options
collection="coll"
property="id"
labelProperty="username"/>
</bean:define>
</html:select>
