Error when executing web report.

rbuser

Hi!

http://localhost:82/WebReport.dll?content=viewer&volume=Rapportutforsker&name=Direkte utskrifter\Bekreftelse&filename=bekr2.pdf&path=c:\PDFStore\&silent=true&newSearch=T&asg0f0se=66607&asg0f1sa=false

When i thought all problems were solved on the webtier this error pops up
when this url is entered. " A component named ppAutoSearchDialog already
exists". What can i do in webtier to prevent this?

Best regards,
Terje

Try a simple test using a ClientReport object to run the same report. Does
that work?

Try running the report server application under the Delphi debugger. If an
error occurs examine the call stack.

Try running the WebTier as a web debugger application. If an error occurs
examine the call stack.

Have never heard of that error.

Yes it works.

This works. It creates a pdf and no preview.

Works with no error.

On my computer:
1. I use the webtier as shown in previous mail "Webtier hang". When i run a
report with no parameters it works well with preview or without
preview generating a pdf.

2. When i run a report with parameters it works in preview but not without
preview. It creates a pdf with no content
that is not possible to open. And nothing else happens until a timeout
occurs. Profiler show that no query is ever run from the report.

On the server it is intended to run.
1. Same.
2.When i run a report with parameters it works in preview but not without
preview. When i attempt 'silent = true' and the ClientReport is used it
generates the before mentioned error " A component named ppAutoSearchDialog
already exists".

In my 15 years of delphi programming i have never experienced this kind of
trouble getting something to work. What can i do now?

I don't understand. Are you running this as a standard app? As a web
debugger app?

Run this in the web app debugger, what happens?


I don't understand this statement.


I don't understand this statement.


When you run this in the web app debugger what happens?

Does the report contain AutoSearch parameters?

You might want to modify one of the demos included with RB to recreate the
error. Then zip it up and send it to support@

Verbally trying to explain an issue often does not lead to the solution.
Either the customer leaves out important details or the tech support
engineer does not understand. It also prevents the use of tools like the
debugger. That is why we ask for an example that we can examine and run
here.

Hi Nard,

Thanks for your patience. I have got it running now with a simple report
with one parameter. The report that fails with the message "a component
named ppAutoSearchDialog already exists" has two subreports. Can this be the
problem? Where and when is the component ppAutoSearchDialog created? Is
there a way i can "rename" this in code?

Regards,
Terje

The ppAutoSearchDialog refers to the AutoSearchDialog that is displayed by
the Report and ClientReport. For a WebTier application, it should never be
created.

A good debugging technique is to create the simplest report and then
incrementally add complexity, testing at each small increment, until you
find the cause of the issue.
