Strange Exception on Consuming Simple Webservice

sharad · 2014-01-22

Hello Friends,

I have made a CU with a single function to insert some data to a table and publish this CU. When I consume this Service It gives the 1st time exception - "Object of type Page with id 50087 could not be found.". I don't have this page. 2nd time Exception - Metadata for object of type Page with id 50087 is in a failed state. This is caused by a previous exception: Object of type Page with id 50087 could not be found.. For this I follow steps provide in this link http://saurav-nav.blogspot.in/2012/02/metadata-for-object-of-type-table-with.html . Multiple time Restarted Services of NAV and Sql but not done. Then I made a page of the same table after doing this a new Exception generate - "Client callback (such as showing Pages) is not supported when executing custom Web services.".

I have a very simple CodeUnit as given Below

OnRun()

CreatePullOutReq(TransactionID : Text[200];RequestBy : Code[20];VehicleID : Code[20];RequestID : Code[20];Reason : Text[30])
IF GUIALLOWED THEN BEGIN
EntryNo:=0;
RecWebAppTransactions.RESET;
IF RecWebAppTransactions.FINDLAST THEN
EntryNo:= RecWebAppTransactions."Entry No."
ELSE
EntryNo:=0;
RecWebAppTransactions.INIT;
RecWebAppTransactions."Entry No." := EntryNo+1;
RecWebAppTransactions.Type := RecWebAppTransactions.Type::"4";
RecWebAppTransactions."Document No." := RequestID;
RecWebAppTransactions."Vehicle Id" :=VehicleID;
RecWebAppTransactions."Document Date" := TODAY;
RecWebAppTransactions."Confirmation Date" := TODAY;
RecWebAppTransactions.Remarks := Reason;
RecWebAppTransactions.INSERT;
END;

and Asp.Net Code

protected void Button1_Click(object sender, EventArgs e)
{

NetworkCredential nc1 = new NetworkCredential("Administrator", "abc", "1.1.1.1");
ws3.Credentials = nc1;
ws3.CreatePullOutReq("CDEF7890-ABCD-0123-1234-567890BABDBF", "Web", "FA000001", "REQ-00001", "Break Fail");

}
I waste much time on this but can't understand why this exception occur.

Please Help me on this.

Thanks in Advance.

Hi sharad,

On which version you are trying this?

I think the error is from the dotnet part of the application not from the Navision. I will try to replicate it in NAV 2013 R2 and will update you.

Hi Saurav,

I am using NAV2009 R2.

Not much help, but I would try making the web service even simpler. "Hello World" or "Capitalize" This might help identify where the problem is.

Client callback errors are there to warn your code is showing a confirm or message. Try it out in classic.

Hi Friends

There is no confirmation dialog or message i return. simple insertion process is there in codeunit. I can't understand why this problem occur. Please Help.

Hi sharad,

I tried to replicate the issue in NAV 2013 R2 and was able to find it. I hope the changes suggested below should resolve your issue -

1) Created a table as per your design (Hope so).
2) Created a codeunit as per your code. (Modified code - Why GUIALLOWED?)

3) Created a DotNet Application and the code is as shown below (Why Code for authentication is so tough?)

4) I run the code and here is the output in my table.

Let me know if I missed anything. I hope you will be able to resolve the problem that you are facing.
