How to load initial instance posted to new form

Hi Hank,

 

Thanks for the reply.

 

Ideally, yes, I would like it the 1st form to be submitted to the 2nd form and the 2nd form can use the value submitted from the first form.

 

However, as I was told previously, the 1st form will submit its data as xml in the body and the 2nd form will load it's initial instance as a request parameter "fr-form-data" encoded in base64 encoding, thus, 2nd form would not be able to pick it up without any intervention.

 

So, I wrote a servlet that intercept the request and inserted a new parameter "fr-form-data" with data that is base64 encoded.

However, if that is not required, I can gladly remove this layer.

 

If the xml submit from the 1st form in the body is

<?xml version="1.0" encoding="UTF-8"?>
<form>
        <section-1>
            <name>Test</name>
        </section-1>
</form>

 

then what is the code that I should write in 2nd form to print out the value submitted from the first form?

 

Thanks in advance for any advice.

Hi Han Ming,

Will the user arrive at the page from another form?  It could be any page that makes the proper post, 

even a regular html form.  Form Runner will handle this -- it appears you have configured it to do so.

As I understand, FR will handle the post and you don't need to edit the source to add the 

input:instance.

Also in FR, if you enter values into the input fields you create, they become the initial 

values when the form is loaded.  Perhaps that is all that you need?

Regards,

Hank

Hi,

 

I'm trying to follow the instruction at

http://wiki.orbeon.com/forms/doc/developer-guide/configuration-properties/configuration-properties-form-runner#TOC-Initial-instance

to load the initial instance posted to the form with a base64 encoded parameter "fr-form-data"

I did add in

<property as="xs:boolean" name="oxf.fr.detail.new.accept-post.*.*" value="true"/>

to my properties-local.xml

 

However, I'm not sure how can I load this data.

I try to follow the instruction at

http://wiki.orbeon.com/forms/how-to/load-initial-form-data

ie.

<xforms:instance id="fr-form-data" src="input:instance"/>

 

Is this correct?

 

When I try to do

<xforms:output ref="instance('fr-form-data')"/>

It always show the path of my form

e.g.

My form url is http://localhost:8080/orbeon/fr/test/TestForm/new

Then, the output will be testTestFormnew

 

<xforms:output ref="instance('fr-form-data')/form/control-1/field-1"/>

Will show empty value

 

What is the correct way of doing it?

 

Thanks.

Hi Hank,

 

Sorry for my late reply.

 

Thanks for the tip.

 

I still have to test it out.

In the meantime, I try testing the following.

 

Form1 with the fr-form-instance as follows

<form>

  <section-1>
    <name />

  </section-1>
</form>

 

It will submit to a servlet which will convert the xml body to a fr-form-instance parameter with the xml changed to a base64 encoding, then it will redirect the request to /test/Form2/new

My Form2 has the following fr-form-instance

<form>

  <section-1>
    <name />

  </section-1>

  <section-2>
    <address />

  </section-2>
</form>

 

This time, the data I have keyed in at Form1 is loaded on Form2.

However, I found 2 problems which I would greatly appreciate some help.

 

1) as you can see Form2 has the extra section-2 and address.

but if Form1 initial instance submitted to Form2 does not have these defined, the field will not even show.

ie. my Form2 is loaded with the name value in Form1, but the Form2 does not display text input for address at all

 

2) if I set any of the field visibility to "false", the value is not sent.

e.g.

in Form1, I have an extra field called "hidden" with a default value set but visibility set to "false"

I can't see this "hidden" field in the xml content, thus, no value is able to be read in my servlet or Form2.

 

I can more or less manipulate to merge Form1 and Form2 xml schema.

But 2nd problem is difficult for me to get around because if the value is not even available, I can do anything about it.

 

Have I missed anything obvious for specifying a hidden field?

 

Any advice is greatly appreciated.

 

Thanks.

Hi Han,

Sorry not much help lately....

I am taking a best guess here. 

The xforms-model-ready event is helpful within the model to process 

data before the form is active for the user.  It occurs only once when 

the form is loaded.  You can call xpl scripts or use insert and xpath 

functions to manipulate the base64 instance into the fr-form-data

(it being declared but empty).

Not that the following will work, cut and paste:

<xf:model id="fr-form-model">

  <xf:action ev:event="xforms-ready">

    <xf:insert nodeset="instance('real-fr-instance')" origin="xxforms:call-xpl('oxf:/some-base64-translator-script.xpl', 'data', instance('input:instance'), 'data')"/>

</xf:action>

  <xf:instance id="real-fr-instance">

    <form xmlns=""/>

  </xf:instance>

</xf:model>
