John,
The #foreach with a List class works fine. The following method of setting
up a default value for a Role where no selection currently exists fixed my
problem. I use this technique all over the place because it is so
convienient.
In my pull tool
public List getAllRoles() throws Exception
{
Criteria crit = new Criteria();
List
roles=org.apache.turbine.om.security.peer.RolePeer.doSelect(crit);
return roles;
}
Then in my template I have:
## Set up entries in the roleType drop-down
#set ( $userRoles = $entitylist.getAllRoles() )
#if (!$selectedRole && ($userRoles.size()>0) )
#set ( $selectedRole=$userRoles.get(0) )
#end
So if $selectedRole exists in the Context from a previous look at this
screen all is fine, if I have not been to the screen before then it selects
a value for me. I also use the $userRoles in a #foreach to populate a
'select' on the same screen, thus:
#rwLabelCell ("Role")
<td width="$ui.screenWidgetWidth" >
<select name="selectedRoleType">
#foreach ($role in $userRoles)
#if ($role.getName() ==
$selectedRole.getName())
<option
selected>$!role.getName()</option>
#else
<option>$!role.getName()</option>
#end
#end
</select>
</td>
Being fairly new to Java I was a bit unsure about what methods I could use
with a [] in VTL so that lead me to use a List class.

Try creating the List as an ArrayList and copying the elements into it
using a loop. I assume this will work as you say you are not having
problems with other List types.
Also does a #foreach using the List created by Arrays.asList work? I am
using this function and have not noticed a problem, but off the top of
my head i do not know that i ever call size() from a template on the
resulting list.
If the problem appears to be in the object created by Arrays.asList, I
would mention it on the velocity list. Not sure whether this would be a
problem with velocity, but it could save some other users the trouble of
getting the same error.
