Forte returned the following error to my browser during template
processeing:
qqsp_Exception caught while executing EXECUTE tag named
CISScanner.LoadCurrencySet Original message: Can't
find interpreted method in GetMethodInfo for class TagHandlerIFace method 2
on object of class CISScanner.
Error detected at method: HTMLScanner::HandleExecuteBlock, Line: 0
Is Forte telling me it can't find the method signature of the class that is
implementing the
TagHandler interface? CISScanner is subclassed off of HTMLScanner so it
should automatically implement the proper interface. My HandleTag method
is not being invoked at all. Any ideas what could be wrong. Thanks in
advance.... Here are some clips of code:

<?forte execute LoadCurrencySet ResultSet="CurrSet">
<TABLE BORDER=3 WIDTH=100 CELLPADDING=3 CELLSPACING=2>
****** HandleTemplateRequest Method ******
return CISScannerSO.HandleTemplate(request);
****** HandleTag method ******
if Tag.Compare(source='LoadCurrencySet',ignorecase=true) = 0 then
currSet : Array of CURRClass = new;
SQL select CURR_ISO, CURR_NAME
into :currSet
from CTP_CURR on session CISDBService;
rset.Add(listName='currList',row=1,
attributeName='Name', value=textdata('ANY'));
rset.Add(listName='currList',row=1,
attributeName='Desc', value=textdata('Any Currency'));

Richard,
I have encountered the same problem. Although the HTMLScanner you have
called CISScanner should have the TagHandlerIFace automatically
implemented, it doesn't appear to be.
Try going into the class properties of your HTMLScanner subclass, and
explicitly put in HTTP.TagHandlerIFace into the
interfaces implemented area. I think this will fix your problem for now,
as it did when I encountered the same problem.
Please let me know if this works for you.
