It seems you were reading my mind ;-)
I just coded that a few hours ago and it works.

Thanks a lot.

ps: I'm starting a new thread about my concerns using XMLForm with
Xindice...I'm almost there, but would need a but of help :-)

Actually what you describe is the correct behavior of repeat.
If you look at the W3C XForms spec, it says that repeat will render the
nodeset which satisfies the XPath selector.

How many boxes do you expect to render?
One solution is to change the getter method for the languages property, so
that it pads the array with blank entries to match the value of
descriptionsNumber if the array's current size() is less than that of
descriptionsNumber .

I think I've almost got it:


Language (code):



And I have in the model bean:
...
private int descriptionsNumber = 1;
private List languages = new ArrayList();
...
public InsertBean () {
initLanguages();
}

public void initLanguages() {
languages.add("en");
languages.add("es");
}
...

And the 'descriptionsNumber' is filled on a previous step in the form
wizard.
But...oh yes, there's a but, I can only generate in the repeat as many input
boxes as elements the 'languages' ArrayList have. It seems that it doesn't
show more than two of them no matter the number I put to fill the
'descriptionsNumber' field. If I put 1, it shows just one field, if I put 2,
it shows two fields, if I put three or more, it only shows two anyway. I
guess that's because the ArrayList only have two elements and the rest of
the calls return null.
Is there a workaround?
I think I'll try looking at the source code of the transformer...

Best.
