Cannot Display Graphic in Viewing Model Results

Question

In our project, we use a clustering model. After having trained the model, we try to view model result in graphic such as Influence Chart. Unfortunately, this problem occurs.
<u>Note.</u>
when clicking 'Inter and Intra Cluster Distances Information,' we find the error message 'Error displaying additional information about clusters.'
<u>Details of this message</u>
Diagnosis
Error occurred while generating graphs for displaying the additional clustering information.
Procedure
Ensure that the RFC destination IGS_RFC_DEST is configured to 6.2 or above version for the Internet Graphics Server (IGS).

Answer 1

If you have reimported the model or removed/added the controller to view context, the binding would have broken.  Make sure you see the outward arrow visible on the model attributes of view context exist, otherwise rebind the context to component controller or custom controller structures.
Another tips is
You can try to display the size of the BAPI return output object, if it's 0 then there is no data returned.  I mean in the component controller you would have written retrieve method to fetch data from backend
wdContext.node<your BAPI>_Input().
                   current<your BAPI>_InputElement().
                   modelObject().execute();
After executing above code, check your output object return code or message lines or a structure object size information.  If nothing is returned then there is a problem, sometimes return code and message lines will return something if your backend BAPI is executed.
Or as above posted suggested put external breakpoints in your BAPI and make sure the input parameters are correct. 
Hope this helps
