Re: map-backed forms with multibox/multiselect lists?

[Radu Badita]

That's great! Thanks for sharing.
Next time I'll know how to do it. Luckily you proved to be more 
determined and finally solved it. Congratulations!

The good news is that this DOES work.
I simply declared my methods to be
public void setFoo(String key, String[] foos)
{
...
}
public String[] getFoo(String key)
{
...
}
and everything works fine. It took a detour through the Struts
source (and ultimately from there through the beanutils source)
to figure this out, but the problem was essentially that when
doing the bean introspection, the beanutils first finds the getFoo()
method and stores its return type. It then looks for a setFoo()
method with the same argument type as the return type of getFoo().
If you try to return foo as an Object, it just won't work -- your
setter won't be found and the method will never be called.
thanks for the input,
Mike

I had the same problem some time ago (the solution vaguely 
suggested by 
Jack wouldn't had been an option since the properties were 
dynamic so I 
needed the key to distinguish between them). I asked on this 
list for help 
at that time, but didn't got an answer, so I guess nobody 
succeeded in 
doing something like this. Therefore I had to find some other 
solution to 
my problem...
I'm guessing this might be some sort of a problem with 
commons-binutils 
(although public void setFoos(String key, String[] foos) 
isn't a valid 
javabeans setter so maybe it's just a bit out of it's scope).

This works fine for list-backed form items (which we also use)
but in this case I need something like
public void setFoos(String key, String[] foos)
is this possible?
There are several workarounds I can think of, but this appears
to be the cleanest solution if I can make it work.

I'm trying to build a form element that combines the
         

features of a map-backed
       

property with a multibox (and the same for a
         

multiple-selection list). I've made
       

multiboxes work fine without the map-backed element, but I
         

can't seem to get
       

this to work.
I've tried various method signatures in my form bean, but
         

to no avail. For
       

example, for a field called "foo" I have tried the following:
public void setFoo(String key, Object val)
{
...
}
or
public void setFoo(String key, String[] val)
{
...
}
I'm using a set of checkboxes on the JSP which should
         

result in a list of the
       

values of whichever boxes are selected. I can think of a
         

number of javascript
       

workarounds, as well as workarounds in my Action that go
         

directly to the request
       

parameters... but all of those are kludges and it seems
         

like there should be a
       

way to have multiple checkboxes that all reference a
         

map-backed form property.
       

Any thoughts?
thanks a bunch,
Mike Nidel
