Does Intake work for 'select' fields?

[Dan E.]

Hello:

I am trying to validate that at least ONE item has been selected from a
selection box using Intake. Is this possible? The selction list has one or
more items in it and the user can perform multiple selctions from those
items. I tried the following, but I dont get an error if nothing is
selected.

<select name="$createUserAccountGroup.Catalog.Key" multiple size="4">
            #foreach ($catalog in $catalogList)
                    <option>$catalog</option>
                #end
</select>

The corresponding intake field is:

<field name="Catalog" key="Catalog" type="String" multiValued="true">
        <rule name="required" value="true">A catalog(s) selection is
required</rule>
        <rule name="mask" value="^[A-Z]+">Please select a valid catalog
name</rule>     
</field>

Als if and when this works, how do I read the values selected in my action
class? See below
try
        {
            createUserAccountGroup = intake.get("Createuseraccount",
IntakeTool.DEFAULT_KEY);
        }
        catch (Exception e)
        {
            System.out.println("Unable to get Createuseraccount group. " +
e.getMessage());
        }
        
        try
        {
            java.lang.reflect.Array catalogs = (java.lang.reflect.Array)
createUserAccountGroup.get("Catalog").getValue();
            System.out.println(catalogs);
        }
        catch (Exception e)
        {
            ........
        }


Also, is there a definition of 'NumberKey', 'StringKey', and 'ComboKey' 
types as shown in intake.dtd?

Thanks.  
Dan
