More than one model in a form

Hi!

I tried to operate with a form having more than one model but it doesn’t work at all.

We want to have a modular ‚library‘ of models and appropriate forms which we can plug-in to make the needed operations available in several XForms forms.

Whenever I try to send a submission not included in the first model in the XForms definitions in the view.xhtml it doesn’t happen anything.

The submission request is just ignored. Not even the xforms-submit-error is executed.

If i insert the additional model into the first model there is no reaction at all and it isn’t even displayed (includes do work, there are several other ones in the form and the xi:include namespace is defined). The other model isn’t even recogniozed (model is not shown in the widget and the instances are not available).

If I insert it before the other models the main form is broken and I get a lot of errors about not recognized variables (which means to me, the second model isn’t read properly).

And that’s exactly the same when inserted after the main model.

If inserted after the first model, the second is shown, but you can’t interact with it.

I thought Orbeon can handle multiple models?

I’ve got the following ‚additional‘ model:

<?xml version="1.0" encoding="UTF-8"?>
<xforms:model id="additional" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:xforms="http://www.w3.org/2002/xforms" xmlns:f="http://orbeon.org/oxf/xml/formatting" xmlns:xxforms="http://orbeon.org/oxf/xml/xforms" xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xxi="http://orbeon.org/oxf/xml/xinclude" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:widget="http://orbeon.org/oxf/xml/widget" xmlns:ev="http://www.w3.org/2001/xml-events" xmlns:xdt="http://www.w3.org/2005/xpath-datatypes" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <xforms:instance id="instA">
        <foo xmlns="" />
    </xforms:instance>

    <xforms:instance id=" instB">
        <bar xmlns="" />
    </xforms:instance>

...

</xforms:model>

There is a submission inside this model and the two instances.

I tried the following includes:

...

<xforms:model id=“main“>

...

<xi:include href=“additional_model.xhtml“ />

</xforms:model>

...

Does not recognize any instances within the additional model.

...

<xi:include href=“additional_model.xhtml“ />

<xforms:model id=“main“>

...

</xforms:model>

...

Causes failures in actions related to the main model (because they are not addressed to a specific model, i.e. they use the first model).

...

<xforms:model id=“main“>

...

</xforms:model>

<xi:include href=“additional_model.xhtml“ />

...

Model is available tot he widget but instances can not be addressed within xforms:listitem, xforms:submit etc. neither by calling xxforms:instance nor by instance.

How can I get information from the additional model?

Any suggestions else to setup a modular model system?

Who uses multiple models in a XForm, who uses xi:includes to have a kind of plug-in architecture? What are your experiences?

Regards and thx a lot in advance,

Thorsten

Thorsten,

I am not sure why it's not working for you, but multiple models are
fully supported in Orbeon Forms. We use this heavily in particular in
Form Runner, where we do include such a "library" of external models
with XInclude.

Best would be if you could create a small example where multiple
models don't work. There is probably a simple explanation.

In reply to this post by Thorsten Stumpf

Thorsten,

I am not sure if this is the problem you're having, but note that if
you are doing anything in the view that references something from a
model other than the first one, you need to switch to that model, with
the model attribute.

So if you have my-model-a and my-model-b declared in that order, if in
the view you want to run a submission my-submission declared in
model-b, you need to write <xforms:send model="model-b"
submission="my-submission">. Also, switching to another model applies
to child elements: if part of your view is related to my-model-b, you
can put it inside an <xforms:group model="my-model-b"> so you don't
have to repeat that model attribute all over the place.

I hope this helps,

Alex

AW: Re: More than one model in a form

Hi!

I'm really trying to find a explanation but as of yet I'm not that successfull.
Our form is quite complex so maybe we're using something in combination which is causing the problem.

The submission seems to be blocked. The log looks quite fine. But when I click on the submit button the result are not ok or it is not send at all.
I'm going to digg deeper on that soon.

Thx,

JT

Sounds good. With full logging, you should be able to tell if/how/when
the submission is stuck.
