Issue/Introduction

All latest Gen 8.6 Toolset PTFs installed up to and including TSN86215.

Create a new CAB in a model and add a Call External statement.
On the "Select WSDL Method" dialog after the WSDL file is parsed select the displayed method and press the Add button.
The Toolset reports error "CA Gen Internal Fatal Error" with "Memory error: undefined record occurrence (type: 0, number: -1)." and crashes:



After the Toolset crashes also see this in Windows Event Viewer (Windows Logs > Application)

With slightly different versions of the WSDL file, the same error message occurs with a different type value e.g. 44, 130.

Validating the WSDL file using Visual Studio 2017 shows 0 errors and warnings and 6 informational.

What is the cause of the error?

Environment

Release : 8.6
Component : Gen Workstation Toolset

Resolution

In the WSDL file which causes the error there is a single element which is very simple and contains no complex types (no xsd:complexType) i.e.:
+++++
   <wsdl:types>
      <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
         <xsd:element name="ELEMENT1" type="xsd:string" />
      </xsd:schema>
   </wsdl:types>
+++++

Previously a larger wsdl file containing complex types (xsd:complexType) was being loaded successfully.
After changing the above definition of element ELEMENT1 to be a complexType the error did not occur i.e.
+++++
   <wsdl:types>
      <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
         <xsd:element name="ELEMENT1">
            <xsd:complexType>
               <xsd:sequence>
                  <xsd:element name="HEADER" type="xsd:string" minOccurs="0" />
                  <xsd:element name="HEADER2" type="xsd:string" minOccurs="0" />
               </xsd:sequence>
            </xsd:complexType>
         </xsd:element>
      </xsd:schema>
   </wsdl:types>
+++++

Therefore there appears to be a limitation that Call External requires the use of xsd:complexType in element definitions.
