Repeat Grid - Iteration node is not generated

Hi,

Repeater-Grid is not generating the XML data with '-iteration' root element.
This happens when I submit the form to an external service.

The form is created from form builder.

</xh:html>

When saving the repeat content the XML generated looks like below.

                        <grid-2>
                             <control-4>test</control-4>
                            </grid-2>
                           <grid-2>
                               <control-4>test-2</control-4>
                            </grid-2>
instead of,
                          <grid-2>
                            <grid-2-iteration>
                                <control-4>test</control-4>
                            </grid-2-iteration>
                           <grid-2-iteration>
                                <control-4>test-2</control-4>
                            </grid-2-iteration>
                        </grid-2>

This is causing problem when I try to pre-populate the form in edit mode.

Thanks,
                       

Hi Karthi,

So you're saying that you would like to have those iteration elements present when you're sending the data to service, correct? If you're doing this with send() in a workflow, you can set data-format-version = "edge", and the iteration parameter will be present. You'll let us know if this works for you.

Hi Alessandro,

Thanks. It works. but now, some of elements (i found that its all hidden when working with the form runner) are excluded from the sent XML.

Though functionally hidden elements are not required, we need few node be available always.
PS: This was working fine as expected before 'data-format-version' is set to 'edge'.

Thanks,

Hi Karthi,

Could you try adding the attributes prune="false", in case you don't have it already? (Note that the default value is true, and for more on this see the section linked below.)

Hi Alessandro ,
Thanks Much !!!
That worked.. I don't know how did I miss that parameter from your last answer .. thanks again.

Hi Karthi,

Excellent! I'm glad adding that parameter solved the problem, and thank you for the update.
