Ignacio & Samuel,
This kind of things do happen with the way ND4 event model works. (Still a
little mysterious to me. Haven't seen a documentation that says it all). If
you do:
=====================
CSpHtml.reset();
load(someOtherPage);
return false;
=====================
you are guaranteed to get the result you expect only if you trigger this
piece of code from an event of the Page itself.
So the solution :
Assuming your current page is pgMain,
Inside the Data Object, set a flag of the page:
======================================================================
public int this_onAfterExecuteEvent(CSpDataObjectEvent event)
{
----
----
if(errorCode!=0)
{
CSpHtml.reset();
((pgMain)CSpider.getPage("pgMain")).loadErrorPage = true;
//loadErrorPage is an instance boolean of pgMain, inited to
false in this_onBeforeDisplay() of pgMain
return (STOP);
}
}
====================================================================
Inside the pgMain do the actual stuff:
public int this_onBeforeHtmlOutput(.. ) {
if (loadErrorPage) {
CSpHtml.reset();
CSpPage pg = CSpider.getPage("pgDOError");
pg.setDisplayFieldValue("txtErrorCode", new
CSpInteger (errorCode));
pg.load( false);
return (STOP);
}
}
====================================================================
If the page has other 'heavy' elements that follows our element in the page,
you could save some processing time by checking for this flag and bypassing
the operation in the onBeforeDisplayEvent() of those heavy elements.
Regards,
Aby
