[Developers] mjt script to display any topic with a specified date

[Nick Thompson]

hard to say what's going on - you must be using q1 somewhere else because
it doesn't show up inside showTopic().

i think what you want is something like this.  note that you need to do
some mjt.script magic to set up the second query, because you need to
ask for a property that was passed in as an argument:

                 UNTESTED CODE!

                 <div mjt.def="showTopic(type,property,startdate,enddate)">
                    <pre mjt.script="">
                       /* need some js to build the query */
                       var taskq = {name: null, type: type};
                       taskq[property] = [{
                                           "value":null,
                                           "value<":"1959-01-01",
                                           "value>":"1957-12-31"
                                         }];
                    </pre>

                    <div mjt.task="q2">
                       mjt.mqlread([taskq])
                    </div>

                    <div mjt.if="q2.state=='ready'">
                         ... show q2.result ...
                    </div>

                 </div>


                 <div mjt.task="q1">...</div>

                 <div mjt.if="q1.state=='ready'">
                   <div mjt.for="r in q1.result"
                     <div mjt.for="prop in r.properties">
                       ${showTopic(r.type, prop.id, startdate, enddate)}
                     </div>
                   </div>
                 </div>

let me know how that works...
