XPM inline editing of Multi-valued field inside a multi-valued embedded field

Question

I have a schema with a multi-valued embedded field, which further have multi-valued text field. Need to loop through the embedded field first and then loop through the multi-valued text field - using XPM tags.

I have read the documentation of XPM where FieldStartMarker fields and its use has been described, but not able to get it work for this scenario.

Component Name: Header
-- Multi-valued Embedded Field: contact_us
---- Single text field: title
---- Multi-valued field: contactnum

Following is the component source XML:

<header>
  <contact_details>
    <title>Title1:</title>
    <contactnum>123456</contactnum>
    <contactnum>234567</contactnum>
  </contact_details>
  <contact_details>
    <title>Title2:</title>
    <contactnum>123456</contactnum>
    <contactnum>234567</contactnum>
  </contact_details>
  <contact_details>
    <title>Title3:</title>
    <contactnum>444555</contactnum>
  </contact_details>
</header>

For title (single text field), the following markup is working fine:

<!-- TemplateBeginRepeat name="contact_details" -->
@@FieldStartMarker("contact_details[${TemplateRepeatIndex}].title")@@
    @@FieldValueStartMarker()@@
      @@GetFieldValue("contact_details[${TemplateRepeatIndex}].title", 0)@@
    @@FieldValueEndMarker()@@
@@FieldEndMarker()@@
<---- here one more TemplateBeginRepeat, to loop through contactnum, with XPM tags ---->
<!-- TemplateEndRepeat -->

Inner loop i'm trying (which is not working) is as below:

  @@FieldStartMarker("contact_details[${TemplateRepeatIndex}].contactnum")@@
     <!-- TemplateBeginRepeat name="contact_details[${TemplateRepeatIndex}].contactnum" -->
         @@FieldValueStartMarker(TemplateRepeatIndex)@@
            @@GetFieldValue("Field.contactnum", TemplateRepeatIndex)@@
         @@FieldValueEndMarker()@@
     <!-- TemplateEndRepeat -->
  @@FieldEndMarker()@@

Please help me out to put correct markups. Here I need to make sure inline editing for "title" field as well, and then the multi-value contactnum field.

EDIT(1):

I have tried putting the following markup:

@@FieldStartMarker("contact_details")@@ <!-- TemplateBeginRepeat name="contact_details" --> <div> <h4> @@FieldStartMarker("contact_details[${TemplateRepeatIndex}].title")@@ @@FieldValueStartMarker()@@ @@GetFieldValue("contact_details[${TemplateRepeatIndex}].title", 0)@@ @@FieldValueEndMarker()@@ @@FieldEndMarker()@@ </h4> <p> @@FieldValueStartMarker(TemplateRepeatIndex)@@ @@FieldStartMarker("Field.contactnum")@@ <!-- TemplateBeginRepeat name="Field.contactnum" --> <span> @@FieldValueStartMarker(TemplateRepeatIndex)@@ @@GetFieldValue(FieldPath + ".contactnum", TemplateRepeatIndex)@@ @@FieldValueEndMarker()@@ </span> <!-- TemplateEndRepeat --> @@FieldEndMarker()@@ @@FieldValueEndMarker()@@ </p> </div> <!-- TemplateEndRepeat --> @@FieldEndMarker()@@

But it is throwing an error:

(80040801) FieldStartMarker does not have a FieldEndMarker.

EDIT(2) The error has been resolved by putting the following markup.
@@FieldStartMarker("contact_details")@@ <!-- TemplateBeginRepeat name="contact_details" --> <div> @@FieldStartMarker("contact_details[${TemplateRepeatIndex}].title")@@ @@FieldValueStartMarker()@@ @@GetFieldValue(FieldPath + ".title", 0)@@ @@FieldValueEndMarker()@@ @@FieldEndMarker()@@ <p> @@FieldValueStartMarker(TemplateRepeatIndex)@@ @@FieldStartMarker("contact_details[${TemplateRepeatIndex}].contactnum")@@ <!-- TemplateBeginRepeat name="Field.contactnum" --> <span> @@FieldValueStartMarker(TemplateRepeatIndex)@@ @@GetFieldValue(FieldPath + ".contactnum", TemplateRepeatIndex)@@ @@FieldValueEndMarker()@@ </span> <!-- TemplateEndRepeat --> @@FieldEndMarker()@@ @@FieldValueEndMarker()@@ </p> </div> <!-- TemplateEndRepeat --> @@FieldEndMarker()@@

However, inline editing is still not enabled. Title and contact num are rendering properly, but not editable in XPM.

The following HTML markup is published to the page,

<div>
<span><!-- Start Component Field: {"XPath":"tcm:Content/custom:header/custom:contact_details[1]/custom:title[1]"} -->
Customer service:
</span>
<p>
<span><!-- Start Component Field: {"XPath":"tcm:Content/custom:header/custom:contact_details[1]"} -->
    <span>
        <span><!-- Start Component Field: {"XPath":"tcm:Content/custom:header/custom:contact_details[1]/custom:contactnum[1]"} -->
            (+46) 0123456789
        </span>
    </span>
    <span>
        <span><!-- Start Component Field: {"XPath":"tcm:Content/custom:header/custom:contact_details[1]/custom:contactnum[2]"} -->
            (+46) 0123456789
        </span>
    </span>
    <span>
        <span><!-- Start Component Field: {"XPath":"tcm:Content/custom:header/custom:contact_details[1]/custom:contactnum[3]"} -->
            (+46) 0123456789
        </span>
    </span>
</span>
</p>
</div>

Please let me know if I am missing any tag here. Also, please confirm if the XPath is correct,
"XPath":"tcm:Content/custom:header/custom:contact_details[1]/custom:title[1]",

Answer 1

I understand Tridion 2009 added the FieldPath variable to help handle multi-value embedded fields. For reference see https://stackoverflow.com/q/10309577/395495 and Frank van Puffelen's explanation on how this worked in the Tridion Cookbook Example.

For the new XPM markup, though the methods have changed (and RenderComponentField has been deprecated), you can (probably should) still use FieldPath to reference embedded multi-value fields.

The example from SDL Live Content (requires login) has:

• Multi-valued Embedded Field: body
  • Multi-valued field: section

XML:

<Content xmlns="uuid:8841d68e-7b1b-45cd-a6d6-7e7da5de3ef9">
    <body>
        <section>Blue section</section>
        <section>Green section</section>
    </body>
    <body>
        <section>Yellow section</section>
        <section>Red section</section>
    </body>
</Content>

@@FieldStartMarker("body")@@
  <!-- TemplateBeginRepeat name="body" -->
    @@FieldValueStartMarker(TemplateRepeatIndex)@@
      @@FieldStartMarker(Field.section)@@
        <!-- TemplateBeginRepeat name="Field.section" -->
          @@FieldValueStartMarker(TemplateRepeatIndex)@@
            <div>@@GetFieldValue(FieldPath + ".section", TemplateRepeatIndex)@@</div>
          @@FieldValueEndMarker()@@
        <!-- TemplateEndRepeat -->
      @@FieldEndMarker()@@
    @@FieldValueEndMarker@@
  <!-- TemplateEndRepeat -->
@@FieldEndMarker()@@

I see two differences between the documentation and your example:

1. For FieldStartMarker() you have TemplateRepeatIndex in the second, multi-value call, though I believe TemplateRepeatIndex would still refer to the outer loop (as it did with the old markup).
2. You have "Field.values" instead of using FieldPath as in: @@GetFieldValue(FieldPath + ".section", TemplateRepeatIndex)@@.

Another article with the same example gives the same tip as Frank:

"For extra clarity, while developing your template code, be sure to output the values of FieldPath and TemplateRepeatIndex at the top of every loop with a statement such as: (FieldPath=@@FieldPath@@, TemplateRepeatIndex=@@TemplateRepeatIndex@@)"

Maybe add this check to help troubleshoot as well as your outer loop and output to make it clearer what your markup is doing. :-)
