Hi
I tested it and I am getting a weird result: My main page gets rendered several
times and the block for the clayForEach is not rendered.
The set up is a working Clay template with the following block in it:
....
<span jsfid="clayForEach" bodyJsfid="news" var="myvar" allowBody="false"
value="[EMAIL PROTECTED]>
<div class="story">
<h3>Story Title</h3>
<p>Story body - reduced for simplicity</p>
</div>
</span>
....
a clay template htmlfile news.html:
<div class="story">
<h3><span jsfid="outputText" value="[EMAIL PROTECTED]" />Story Title</h3>
<p><span jsfid="outputText" value="[EMAIL PROTECTED]" />Story body</p>
</div>
and in my clay-config.xml:
<component jsfid="news" extends="clay" id="news">
<attributes>
<set name="clayJsfid" value="/pages/news.html" />
</attributes>
</component>
the method signature for otherTopNews is : public List getOtherTopNews()
Debugging this, I have added an extra catch in the ClayAmalgam.clayForEach
method, catching the case where vi is null at the end. Here I print out the
type of valueList (which should equal the returnvalue of otherTopNews i.e
List). It states that it is of type String!!
I have tried to figure out where it changes from a List to a String, but I am
at a loss.

Oh, right. I forgot the other half of the story. The snippet will use the
managed-bean-name symbol. So, you should code:
template jsdid=/news.xml:
<h3><span jsfid="outputText" value="[EMAIL PROTECTED]" /><h3>
<p><span jsfid="outputText" value="[EMAIL PROTECTED]" /><p>
><span jsfid="clayForeach" bodyJsfid="/news.xml" var="myvar" >allowBody="false">
>bla bla
></span>
You will need a "value" attribtue to bind to which can be a List, Map or Array
types. This is a ValueBinding expression.
<span jsfid="clayForeach" bodyJsfid="/news.xml" var="myvar" value="[EMAIL
PROTECTED]" allowBody="false">

></span>
