Error - The exception, which is assigned to class 'CX_WDR_RT_EXCEPTION'

Question

Hi All,
I get the following error when getting parameters from HTML Form to ABAP Webdynpro Application.
Short text                                                                               
An exception occurred that was not caught.  
What happened?                                                                               
The exception 'CX_WDR_RT_EXCEPTION' was raised, but it was not caught anywhere               
    along the call hierarchy.                                                         
   Since exceptions represent error situations and this error was not adequately responded to, the running ABAP program 'CL_WDR_CLIENT_APPLICATION=====CP' has to be terminated.

Answer 1

It appears that you are using some URL parameters.  You must have supplied a field to hold one of these URL parameters, but the data type is not compatible with the incomming data.  I would suggest setting an external breakpoint in this block of code to determine which URL parameter is causing your problem.
