CSpHtml.reset() gets rid of the Html stuff generated so far, but if you do:
================
CSpHtml.reset();
load("pgEmpty")
return(STOP);
================
on the Repeated1_... event, ND goes ahead and creates HTML stuff for
whatever is there on the Page, after the repeated. The result is the proper
HTML for pgEmpty appended with whatever was on the original page after the
Repeated1 plus the ending tags - </TABLE> </BODY>, </HTML> etc. - a mess.
If you don't want to go manual, what you can do is on the Repeated1_..
event, when 0 records, set a flag and return (STOP)
Inside this_onBeforeHtmlOutput(..), check for this flag and do:
CSpHtml.reset();
load("pgEmpty")
