Issue with radio-button and internationlization

This issue is reproducible on Orbeon 3.8 and 3.9

Here are the steps:

Step 1: Add a radio-button field (unnamed)
Step 2: Add 2 items: I1 and I2 - Fill the labels in only, not the values. Close
the dialog via Apply button. The 2 items appear in the radio-button field area.
Step 3: Add a language for the form (ex: français). The added language becomes
the current language for the form. The 2 items still appear in the radio-button
field.
Setp 4: Edit the radio-button items again and enter a thrid item (label I3, no
value again). Apply the edition. Now there are 3 items for the radio-button.
The current language is still the added one.
Step 5: Switch to the former language (i.e. english in my case). There are 3
itenms again for the radio-button field BUT the third items has no name (the
corresponding radio-button is visible but it has no label)
Step 6: Edit the radio-buttons again
---> BANG: an error dialog opens and
        - it says: "A sequence of more than one item is not allowed as the
first argument of string ()(,)"
        - the details are:
        - Nothing works: no button (Test, save or close), no controls. The same
error dialog always pops up.

Jean-François,

I reproduce the problem with your form.

I notice that the builder, on step 4, incorrectly updated the labels
of the other language. If you look at the source of the form, you now
notice things like:

<item>
    <label>I1</label>
    <label>I2</label>
    <value/>
</item>

The itemset editor doesn't expect this and crashes.

Now funnily enough, we are making some changes at the moment to the
itemset editor for the next release. One change is that there will be
more constraints, including not allowing multiple identical values
(here the blank ones).

I have entered an issue to track this:

https://github.com/orbeon/orbeon-forms/issues/12

We will make sure it does not occur with the updated itemset editor.

-Erik

Hi Jean-Francois,

The new editor we have been working doesn't have this problem. The
logic, dealing with i18n resources has been improved, and also now you
can't create items with an empty value. So I will be closing the issue
opened earlier by Erik.
