forms + binding in repeater + bean + String[] type

[Joose Vettenranta <jo...@iki.fi>]

Hi,

I have bean like this:

class Bean {
  private Collection foo = new ArrayList();

  public addItem (String[] item) {
  ths.foo.add(foo);
  }

  public getFoo() {..}
  ..
}

in binding file, is iti possible to bind to that datatype, or do I  
have to use some wrrapper class?

like
   <fb:repeater id="foo" parent-path="." row-path="foo">
     <fb:identity>
       <fb:value id="id" path="String[0]"/>
    </fb:identity>

     <fb:on-bind>
       <fb:value id="value1" path="String[1] direction="load"/>
       <fb:value id="value2" path="String[2]"/>
    </fb:on-bind>


?

You have to have a bean property to bind to.  You've got a getFoo(), 
but you also need a setFoo() for foo to be a property.  Unless you are 
heinously overloading "foo" in your example above :-), you would not 
set repeater@row-path to 'foo' (and let's not call the repeater 'foo', 
too! :-).

"String[0]" etc. are not going to be valid jxpath components either 
(because that would have to map to a property named 'String').  What 
you want is "foo[0]", "foo[1]", etc. — corresponding to the 'foo' that 
is Bean.foo (forget all those other 'foo's! :-)

cheers,
