Re: [Stripes-users] Two dimensional arrays in actions
My guess as to why it might not be good to name a form button submit is
that form elements can be referenced with formNode.formElementName, but
each form node already has a property named submit that references the
submit function. I guess the function would win, but I'm not sure.

I don't think this affects your code, but I would really
advise against using an event handler method named submit.
I can't remember why exactly at the moment, but I remember that
it's a Really Bad Idea to have an HTML submit button named
submit.
Noted. Thank you. I've got a fair bit of code that uses submit(), so
I'll be doing a fair bit of refactoring. :-)
My experience when dealing with one dimensional arrays (changing
answer[][] to answer1[], answer2[]) is that you get an array of
answers propagated for you. eg. If you speak both English and French,
you get answer2[] = {1, 2}; if you live in Australia you get
answer1[] = {1}
So, I would have thought that with the example I list the code for, if
you live in Australia and speak English and French you should get
answer[][] = {{}, {1}, {1, 2}} (my arrays are one indexed, so
the zero index should be null or an empty array). Is this not the
case?
I would have thought so too. I'll admit I am surprised. I'm not sure
why it doesn't work, but I can tell you that if you change your
property to
public ListListString answer;
you will get what you expect, i.e.
answer = [null, [1], [1, 2]]
I'm hoping you don't mind working with ListListString instead of
String[][]..
Making that one change solved the problem. ListListString works
perfectly, String[][] doesn't. So I'm guessing that's a bug? At least
there's a workaround, and it's not a bad one.
Thanks again for your help. Should I be opening a bug report for this one?
Regards,
Nathan.

Hi Nathan,
A few comments below. Hope that helps.

Not a big deal, but note that you can use just
beanclass=${actionBean.class} in s:form.
And an action that looks like this:
public class SomeAction {
public String[][] answer = null;
@DefaultHandler
public Resolution submit() {
if (answer == null)
logger.debug(No answers provided by customer);
else
logger.debug(String.format(answer[][] first dimension is %d items
long, answer.length));
}
}
I don't think this affects your code, but I would really
advise against using an event handler method named submit.
I can't remember why exactly at the moment, but I remember that
it's a Really Bad Idea to have an HTML submit button named
submit.
When I answer the questions and submit, my debugging output says
answer[][] first dimension is 0 items long. So answer gets set to a
non-null, but of zero length. My reading of the section of the
(excellent) stripes book on indexed properties suggests that I might
be able to do this, but doesn't give an example that maps to exactly
what I'm doing.
Thank you for your kind comment about the book--I'm glad you are
enjoying it. Sorry that I didn't have an example that matches your
use case..
My experience when dealing with one dimensional arrays (changing
answer[][] to answer1[], answer2[]) is that you get an array of
answers propagated for you. eg. If you speak both English and French,
you get answer2[] = {1, 2}; if you live in Australia you get
answer1[] = {1}

answer[][] = {{}, {1}, {1, 2}} (my arrays are one indexed, so

why it doesn't work, but I can tell you that if you change your

you will get what you expect, i.e.
answer = [null, [1], [1, 2]]
I'm hoping you don't mind working with ListListString instead of
String[][]..
If it's an issue, I'll look further into why it doesn't work with
the two-dimensional array.
Cheers,
Freddy
