Problem when WSDL changes for a Web Service Reference

Question

Hi
I have a Web Service Reference that is accessed by several reports and processes within APEX.
The problem that I am experiencing is that, when the Web Service changes, as it has been doing quite often due to development, I can find no way of updating the Web Service Reference in order that the additional input and output parameters become available to the associated reports and processes. The only solution that I have found is to recreate the Web Service Reference going through the same wizard process and giving the Web Service Reference the same name as previously.
However when the Web Service Reference has been recreated all reports and processes that accessed the old web service have blank values for source, input and output parameters. This means that I have to build the reports and processes again from scratch.
Does anyone know of a better method of “refreshing” a web service in order to expose any new inputs or outputs defined with the WSDL without breaking existing functionality?
Regards
Ian

Hi,
My solution is simple: add new service reference, then new methods can be atached to the old service refernce with the followind block
begin
update WWV_FLOW_WS_OPERATIONS fo
set
FO.WS_ID = (select ws.ID from WWV_FLOW_SHARED_WEB_SERVICES ws where ws.FLOW_ID = 117 and ws.NAME= 'WebHINSSvc')
where
FO.NAME not in
(select
FOO.NAME
from WWV_FLOW_WS_OPERATIONS foo
where FOO.WS_ID = (select ws.ID from WWV_FLOW_SHARED_WEB_SERVICES ws where ws.FLOW_ID = 117 and ws.NAME= 'WebHINSSvc')
and FO.WS_ID = (select ws.ID from WWV_FLOW_SHARED_WEB_SERVICES ws where ws.FLOW_ID = 117 and ws.NAME= 'WebHINSSvcNEW')
delete from WWV_FLOW_SHARED_WEB_SERVICES ws where ws.FLOW_ID = 117 and ws.NAME= 'WebHINSSvcNEW';
end;
If you change only params it wont help. Ypu have to recreate the code that breaks again.
I hope this helps.
