Re: free marker issue, Expecting a string, date or number here, Expression instead a freemarker.ext.dom.NodeListModel

I get that message if an attribute doesn't exist.  Make sure it is in the xml and you have the spelling and case correct.

Also in the docs you'll see

${(element.@Attr)!'Undefined'}

Will never give you undefined since @Attr always exists as a 'Node List Model', regardless of whether or not your xml has it.

So you have to check for [0] in the list.. essentially I always use [0] on attributes. 
${(element.@Attr[0])!'Undefined'}

Correct me if I'm wrong, but in xml I believe you can't have <Element Attr="one" Attr="two" />, you'll get a 'duplicate attribute' parsing error.  So why then is @Attr a list with [0], [1], ... [N] .. Why would @Attr ever have more than one value?  What am I missing?

I can't read your message but--

Are you sure there is no more than one gamedate? I suppose tickers["ticker-entry/gamestate"] could be a list.
