No content with multiple datasets in detailregion

Question

I have a detailregion, in which I don't just want to display
data, but want to enable data maintenance via a form. There are
some dynamic select fields, so their datasets are declared together
with the main dataset when the detail region is set up. T
The code used to declare the detailregion is
<div spry:detailregion="routerlist_xml edit_country_xml
edit_region_xml">
The detailregion that should be under the list display is
well - not showing.
When I take the datasets for the select fields away so the
line looks like
<div spry:detailregion="routerlist_xml">
the detailregion displays as expected.
(Of course the browser will complain about the missing
datasets, but that is not the point here).
Is it not possible to have multiple datasets in a
detailregion? If not, what is a workaraound to get a dynamic select
into a detailed field? If yes, is there anything wrong in my code?
Or is there a bug in the Spry framework?
Any pointers are welcome.
Thanks

Trial and error solved the problem.
When there is an error XML the dataset for the dynamic select
field is based on, then the whole region in to which the dataset
was linked will not be shown.
The 'error' in my case, it appears, were non-US keyboard
characters (from a german keyboard). The underlying database mysql
is set to UTF8-unicode, and the xml-export function has
$xmlExportObj->setDBEncoding("UTF-8");
$xmlExportObj->setXMLEncoding("UTF-8");
in its code.
Once those characters were removed, it all worked fine.
To make things even more confusing was the fact that the page
worked fine in Firefox when the detailed region just would not show
in IE7 due to the special characters.
A bug or a compatibality issue for the Adobe crew to check
out ?
