Orbeon with 3 nested combos

I need some help with this.

The point is that I have 3 nested combos, so when I choose an option it loads de second combo (depending on the choice), and when I choose an option of the second combo it loads the third one.

Could someone please help me? I'm using Orbeon with Sql server 2000.

Thanks in advantage,

Enrique

Enrique,
        It all depends how your XML is laid out. If you can post a snippet
it would be helpful.

Enrique,

Impossible to give you an answer if you don't provide some code. If you
haven't written any, unfortunately we cannot develop a full example for
free, but the outline of the code would be:

o create three xforms:select1 controls

o use xforms:itemset to populate the xforms:select1 controls, bound to
separate XForms instances

o catch xforms-value-changed-events when the first control changes

o perform and XForms submission with replace="instance" to update the
second control

o implement a service on the server that responds to the submissions by
retrieving the relevant values from the database, with the SQL processor

And that's pretty much it!

Hi Erik,

I did not wanto you to develop the whole of it. The point is that I did not
have the code itself, so I could not post it.

We are using Orbeon 2.8, and the development team has told me that they
have not seen it in the documentation provided anything related to replace
="instance", so they do not know if they can use it within that version.

I am sending you the instance, which goes as follows. Unfortunately, I am
not myself an expert, so if this is not what you need, please tell me so I
can tell the team to give me what you need.

Thanks in advance,

Enrique

Unfortunately, replace="instance" is not supported with 2.8. You have
to use 3.0 and the new XForms engine to get all the new XForms
features.

Well, I am not sure what *you* need. I can only outline a quick
strategy for doing the same with 2.8.

With 2.8, this is harder to achieve and not as user-friendly. In a
first phase you will need an "Update" button under each list (in a
second phase, you can use JavaScript to submit automatically). That
button will be an xforms:submit. When you press on the button, your
entire XForms instance is submitted. On the server side, you can then
look at the currently selected values in the lists, and fill-out a new
instance appropriately before generating the entire updated page again.

Clearly, the easiest way would be to use 3.0.
