'web service call failed: 500' using ajax hovermenu and web service

[Not Me]

Hi there,

I'm using a hovermenuextender attached to a templatefield of a
gridview, and everything seemed to work fine.. however I've moved on
to add dynamic attributes to the hovermenu. Now I get the error "web
service call failed: 500" in place of the output I want (on the
hovermenu's panel).

When accessing the web service I created (directly through the
browser) everything works fine..

here's my hovermenuextender dynamic attributes

DynamicContextKey='<%=eval("refnumber") %>'
DynamicServiceMethod="GetSearchDetails"
DynamicServicePath="Services.asmx"
DynamicControlID="lbdynamiccontent"

I'm guessing the path or method may be incorrect? I've put
services.asmx in the root folder and services.vb was slipped into the
app_code directory.

The other problem would be with the contextkey, but debugging info
within the webservice never gets thrown (it does when I run the
service directly through the browser) so would a funny parameter do
that?
Any help would be greatly appreciated! I also saw error 12030 instead
of 500 crop up, but that seems to have gone (!!!)

cheers,
Chris

Aha, I realised the helloworld service worked fine.. it was just
anything I created with parameters.. I had my service set up as

Public Function getSearchDetails(ByVal refno As String) As String

so changed this to

Public Function getSearchDetails(ByVal contextKey As String) As String

and all is well!

hope that it useful to any googler's out there.
