Problem with repeat element

Hey guys n' gals!

I'm relatively new to xforms and Orbeon and have pondered the same problem now for a week or so.
I'm uncertain if I fully understand how 'instance' functions and am working on a form with a repeat element.
The problem I'm experiencing is a little tricky but basically whenever I get the repeat element to work all other elements not included within the repeat tag stops working and vice versa.

I've attached the file..

Best regards

Jimmy

Re: Problem with repeat element

Hi Jimmy,

I think everyone has found XForms a bit of a journey,
and an interesting one.

I think what you are seeing is the XPath context, which can be
set by <group ref="..."> and is set to the current item of the
select within a repeat.

To reference data outside this context, you must use the full
XML path to the data, which often must include the particular
instance:

<output ref="instance('some-other-inst')/node"/>

Jimmy,

I see your file, but you don't say how to reproduce the problem:

* what behavior you observe with the current file

* what to change to observe the other behavior

Re: Problem with repeat element

Hi Erik

I am a bit unsure as to whether my main instance is appropriately structured.
In the current file my repeat element is fully functioning but all other elements
represented in my main instance is not..

I'm not quite sure what to make of it. But simplifying the structure of my
main instance will get the other elements working again.

Hope that helps

Hey Hank

Worked like a charm!
Feel I have a better understanding of the repeat function now.

Thanks a bunch

Re: Problem with repeat element

I have another question regarding the repeat element.

When implementing the repeat element in a new form, using the form builder, what do I need to keep in mind?
Would there be a conflict with the control-binds declaring the XPath?
Would I have to declare my button-trigger for the repeat element within the

<fr:buttons>

tag under the

<fr:body>

if I'm also building a wizard?

Currently Form Builder does not support repeats properly. This is actually a feature that we are going to work on first thing right after Orbeon Forms 3.9 is released. We have some ideas here already:

http://wiki.orbeon.com/forms/projects/form-runner-builder/repeated-content

Now there is a complicated way of introducing the repeat by hand by modifying the source code of the form in Form Builder (from "Edit Source"), for example. This involves changing a grid that looks like this:

<fr:grid columns="4">

<xhtml:tr>

...

</xhtml:tr>

...

</fr:grid>

into something like this:

<fr:repeat ref="vehicle" columns="4" id="vehicles-repeat"

<fr:body>

<xhtml:tr>

...

<xhtml:tr>

</fr:body>

</fr:repeat>

You also need to modify the instance data under <xforms:instance id="fr-form-instance"> to introduce a child element for the repeated content. For the "vehicle" example above, you would need:

...

</vehicle>

Finally, the <xforms:bind> section also needs to be modified to reflect all this. The new DMV-14 form is a complete example showing how this is done:

https://github.com/orbeon/orbeon-forms/blob/master/src/resources/forms/orbeon/dmv-14/form/form.xhtml

The <fr:repeat> construct already includes add/remove buttons, so you don't need to add your own, if that's what you mean.

Re: Re: Problem with repeat element

Hi, Erik

I managed to figure it out, finaly. Within the repeat tag I'm able to adjust min and max repeats and set the path to the template.

Thanks for the help.
