The issue:
WSDL method getFormRateItemValues returns an error.
Executing webservices method 'getFormRateItemValues' to get information stored in the form of a CA Service catalog request,
An error was thrown as follows (from view.log):
[RequestServiceImpl] Exception occurred in getFormRateItemValues.
java.lang.NullPointerException
The error message is not detailed and it is impossible to find the root cause.
It had to do with a non proper form definition.
The form contained 2 sets of radios which had exactly the same ID's and values.
After changing the form definition, making the IDs unique, the WSDL executed properly.
