How to call a web-service ofr external validation

Hi,

I tried the xxternal validation sample and its works fine, but I can't see how to change the logic to call a web-service. I have made a web-service operation that takes one parameter, the customer-number and validate it.

Can anyone give me a hint or a sample of how to call this operation, and how to create the request body from the xform.:


            <xf:submission id="validation-submission" ref="instance('user-info')"
                    resource="/apps/xforms-sandbox/samples/howto/external-validation-response.xml"
                    method="post" replace="instance" instance="validation-result">
               
                <xf:delete ev:event="xforms-submit" ref="//@v:*"/>
                <xf:action ev:event="xforms-submit-done">
                   
                    <xf:insert ref="." origin="instance('validation-result')/v:data/*"/>
                   
                    <xf:setvalue iterate="//@v:alert" ref="." value="concat(., ' (save again to revalidate)')"/>
                   
                    <xf:dispatch name="fr-visit-all" targetid="error-summary-incremental"/>
                    <xf:dispatch name="fr-visit-all" targetid="error-summary"/>
                   
                    <xf:refresh/>
                    <xf:dispatch name="fr-update" targetid="error-summary"/>
                </xf:action>
            </xf:submission>

Hi Balatharan,

Are you referring to the how-to linked below? And are you creating your form with Form Builder?

http://wiki.orbeon.com/forms/how-to/logic/external-validation

If that is the case, then this how-to won't help, as it is written for cases where the XForms is written by hand. At this point using HTTP or database services for validation isn't directly supported. However, it can be done, indirectly, through a workaround described here:

Hi Alex,

Thanks for your answer and the link to the workaround...
You are planing to implement this functionality in the near future?

Balatharan,

We don't have immediate plans. The following FAQ applies:
