You can getting away of scriptlet by using <logic:insert> ... with a jsp 1.2 compliant server, or use jstl <c:forEach>.
The examples provided in tiles-documentation should be jsp1.1 compliant, so they use a loop in a scriptlet. But this doesn't really matter, as this scriptlet only occur in a well located jsp. You can think of this jsp as a black box, and don't bother at what there is inside. Your jsp can contain only tag with no scriptlet, and use some layout containing the scriptlet.

Why can't the tag or the tiles controller do something along the lines of instanceof, if the property is a list-type, then process each member of the list to the page? I thought everyone was getting away from scriptlets....

Hi,
The tiles:insert tag don't check if the attribute is a list because
element of the list can be of several kind (def name, URL, Item, custom
bean, ...). Doing an insert on a attribute of type list doesn't means
that you want to insert each element of the list. Maybe you simply want
to display the element.
Take for example the menu layout. It requires as input a list of
"Item". One can customized the "Item": how the insert tag can take into
account such customization ?
In the current proposal, the insert tag just pass the list as is, and
let the programmer play with the list according to what have been pushed
in the list.
