Strange error message when invoking web service

28 Views

Hello,

using the VC 7.1 EhP 1 NWDS I have created a model which invokes a web service as depicted [here|http://img242.imageshack.us/img242/6523/modelxw7.png].

The web service takes a number of plain values and two lists as input.

When testing my model the web service is invoked successfully. The web service operates as expected and the stored information can be found using the service browser as expected.

However, on the web page the following error message is displayed:

Error in Connection : Column null does not exist

What does that mean and how can I get rid of it? Everything seems to work fine.

I have already remove the end point. That did not help. I have checked the mappings, they are fine.

What can I do?

Best regards

Alexander
