I do some reserch and I found that the error is related to the server returns the exception when trying to invoke a dialog UI through a Web service.

Any help. Thanks.

When exposing page/codeunit as a web service, the code should not use end-user confirmation dialog boxes, message boxes, or constructs that will result in a UI interaction . Because a Web service runs independently of a user interface, running this type of code causes the code to throw an exception.

More information about handling UI interaction when working with web services can be found at http://msdn.microsoft.com/en-us/library/dd301080.aspx

I also want to add that if you have any code in CU 1 onopen company etc, like opening a form that shows the current Company, database etc, make sure that you have it changed. to

IF GUIALLOWED THEN
//Run some form etc.
