Subject: Wrapping Collections in LazyList to auto-populate form onSubmit


From the BananaBean example, I put the following in a nested:form
 
nested:iterate property=bananas
nested:text property=flavour/
/nested:iterate

and get this exception:
 
java.lang.IllegalArgumentException: Property 'bananas' is not indexed
 
 
In the form I construct the bananas list using
 
private List bananas = ListUtils.lazyList(new ArrayList(),
  new Factory()
  {
public Object create() {
  return new BananaBean();
}
  });
 
In the display action I populate the list using bananas.add

That's wierd. I use the LazyList all the time and do not run in to that
problem. Did you try using jstl to see if the problem is perhaps somewhere
else.

You will need to import the jstl core taglib and the struts html-el tag
libs.

c:forEach items=requestScope.[you form name].bananas var=bannana
varStatus=status
html:text property=bannans[${status.index}].flavour/
/c:forEach

Have Fun,

Re: Wrapping Collections in LazyList to auto-populate form onSubmit

2003-03-05 Thread alexj 
It's not a good conception that an List can be indexed (an Collection to)
that's suck...
an ArrayList ok but not a simple List... (a simple List don't use an array
as
the internal structure) but for an iterator it's song ok.

But that's my opinion Java data structure are really strange.
