[Actionframework-users] another enhancement request - checkboxes and multiple select

[Mark D. A. <md...@di...>]

I'd like to be able to declare a java method like doSomething(String[] dog)
which would handle:

<input type="checkbox" name="dog" value="beagle"/>
<input type="checkbox" name="dog" value="spitz"/>

or 
<select name="dog" multiple="multiple">
<option value="beagle"/>
<option value="spitz"/>
</select>

but that doesn't work because if no dogs are selected, "dog" doesn't show up
at all on the query string.
If I have an array argument, it should allow for no members.

-mda

I would like to my add my vote supporting this suggestion as well.

This would be useful for our application.

Useful! Adding to 0.94 todo :) We would only have trouble with noarg doSo=
mething()
method (overloading). A standard property like org.actionframework.Action=
Servlet.dontMapEmptyToArrays
should allow disabling this feature.

PS: presently, there is a solution for this using <input-variable>:

    <action name="/doSomething" method="doSomething(String[] dog)">
       <input-variable name="dog" value="[]" if="!$dog"/>
       ...
    </action>

This would set dog="empty array" if it is not set in the request.

I'm sorry, this only creates array of length 1. Here's a correction:

<input-variable name="dog" component="Util" value="getEmpty()"
                 if="!$dog"/>

Where Util is a component that has a method:

public class Util {
     private static final String[] array = new String[0];

     public String[] getEmpty() {
         return array;
     }
}

huh? [] has length 1, not 0?

It works like this: dog=new String[] {"[]"};
