Hi David,
there are several possibilities:
1. you pass an object explicitly to an embedded element using http://
rifers.org/docs/api/com/uwyn/rife/engine/
ElementSupport.html#processEmbeddedElement
(com.uwyn.rife.template.Template,%20java.lang.String,%
20java.lang.Object) or http://rifers.org/docs/api/com/uwyn/rife/
engine/ElementSupport.html#processEmbeddedElement
(com.uwyn.rife.template.Template,%20java.lang.String,%
20java.lang.String,%20java.lang.Object) and http://rifers.org/docs/
api/com/uwyn/rife/engine/ElementSupport.html#getEmbedData()
2. you query an embedding element from within the embedding element
when you need data using getEmbeddingElement(), ideally you have some
interface that embedding elements implement to make this better
structure (see and the NewsProvider interface and NewsEntry element
in http://rifers.org/rife_indepth_simple_blog)
3. getEmbedValue() from within the embedded template can be used to
retrieve what's inside the embedded element value tag, however it's
not dynamic and can only refer to default content, you can however do
whatever you want using getEmbeddingTemplate()
4. this is the one I like the less, but you can use
setRequestAttribute(String, Object) in the embedding element and
retrieve the values in the embedded elements using getRequestAttribute
(String)
Hope this help,
Geert

Is there an obvious way to pass a value to an ELEMENT take inside a

http://rifers.org/wiki/display/RIFE/Embedded
+elements#Embeddedelements-3
and use them to get properties as in the label generator, but what
if I need to insert a values at run time so that the embedded
element can pick it up on the fly and go
do its thing?
For example, if I have an element called NEWSBOX (which is
basically a clone of the CMF news item example), how do I pass a
value to NEWSBOX inside the HTML
template that's using it..? In this case NEWSBOX takes an integer
parameter which is the object id in of something the content
management framework.
E.g.,:
<table>
<tr>
<!--V 'ELEMENT:.NEWSBOX'--> <!--V
'cmfid' /--> <!--/V-->
</tr>
