How to handle nested repeating regions in Dreamweaver TBBs in SDL Tridion 2011 SP1

The Tridion practice page that Neil referred to is a good reference. But that page shows how to generically iterate over all embedded fields. In cases where you know the field name, things get a bit easier. In you case, this is all that is needed in your DWT:

<!-- TemplateBeginRepeat name="body" -->
    <!-- TemplateBeginRepeat name="Field.value" -->
                                               TemplateRepeatIndex)@@ </div>
    <!-- TemplateEndRepeat -->
<!-- TemplateEndRepeat -->

Line by line:

  1. Iterate over the values of the body field of your Component
  2. Iterate over the values of the value subfield of your body embeddable schema
  3. At this stage the FieldPath refers to the current body value, so body[0], body[1], etc. and TemplateRepeatIndex is the index of the current value. So we can construct the correct RenderComponentField call with this knowledge.


I have a Component with two body fields, each with two value fields. So the XML is:

<Content xmlns="uuid:8841d68e-7b1b-45cd-a6d6-7e7da5de3ef9">

The output from the above DWT on this Component is:

<div><tcdl:ComponentField name="body[0].value"
<div><tcdl:ComponentField name="body[0].value" 
<div><tcdl:ComponentField name="body[1].value" 
<div><tcdl:ComponentField name="body[1].value" 

Debugging these situations

Many people have problems writing constructs like these. I am no exception, I have just found that I can get most cases working by knowing that the crucial variables are: Field, FieldPath and TemplateRepeatIndex. When in doubt, simply embed this fragment into your DWT inside every TemplateBeginRepeat.

(FieldPath=@@FieldPath@@, TemplateRepeatIndex=@@TemplateRepeatIndex@@)
