Call to TrsWebRequest fails with "Invalid session"

rbuser

Hello,

I am having a problem handling my webrequest for a report.

In short my code:

var
s: TStringList;
req: TrsWebRequest;

begin
s := TStringlist.create;
try
req := rsWebTier.CreateWebRequest(s, '');
try
// Fill content parameters;
req.ContentParameters["name"].Asstring := "val";

// Fill sessionparameters;
req.SessionParameters['rosession'].asstring := sessionid;
if (rsWebTier.RequiresAutoSearchParameters(Req)) then
begin
**********************
Exception is thrown: Invalid Session!!!!!!
end;
finally
req.free;
end;
finally
s.Free;
end;
end;




I think the error has something to do with tye
SessionParameters['rosession'].

Wat code do I need to use to setup an valid session?

Thanks André Konijnendijk.

Hi André,

Check out the RB Server custom parameters demos. They contains examples of
performing custom processing.

Hi Nard,

I have looked into your examples, but everything looks fine by me in
our code.

I will try to explain what the problem is.
In the attachment you will find a few screenshots from my report
definition.

The report contains 4 linked tables and a seperate one.
A parameter "verlofregelingen" is defined.
When a LookupList is filled and no LookupSettings are defined, the
autosearch screen is shown within the webclient.

When the Lookupsettings are linked to the seperate datapipeline, the
webclient aborts with a message "Invalid Session"

Is there a parameter I need to set in the report?

Thanks for the advice.

André Konijnendijk.

Hi André,

Attachments can be emailed to support@, please do not post any attachments
to the newsgroups.

Please create a simple example that I can build and run here and email to
support@ in zip format. Perhaps use one of the demos as a starting point for
your example.
