Using path:// query syntax - unexpected error

Question

Hi,
I'm trying to use the path://InfoObjects/Root Folder/ syntax. I've followed the User Guide (XI 3.1) and I have the following code:
PagingQueryOptions poptions = new PagingQueryOptions(0);
String pathqry = "path://InfoObjects/Root Folder/Feature Samples/**/[SI_INSTANCE=1]";
IPageResult ips = iStore.getPagingQuery(pathqry, poptions);
Iterator pageResultIter = ips.iterator();
IStatelessPageInfo pageInfo = null;
while(pageResultIter.hasNext()) {
        IStatelessPageInfo    pageInfo = (IStatelessPageInfo) pageResultIter.next();
String pageQuery = pageInfo.getPageSQL();
colInstances = iStore.query(pageQuery);
When I run this I get an Exception at the line:
IStatelessPageInfo    pageInfo = (IStatelessPageInfo) pageResultIter.next();
All the exception says is: java.lang.String.
It's a Casting Exception but it doesn't make sense to me, it should work should it?
Does anyone have any ideas or examples they have using this path:// functionality?
Thanks

Thanks Ted. Your example worked. It uses a slighly different method and is actually a lot simpler than the User Guide sample.
Instead of doing the whole itereator thing you simply have:
sqlStmt = iStore.getStatelessPageInfo("path://Root Folder/", new PagingQueryOptions()).getPageSQL();
which returns the standard Enterprise SQL statement and then off you go as normal using this to query the iStore.
colReports = iStore.query(sqlStmt);
