9.3.4. Upgraded to CivetWeb v1.13

9.4. Known Issues

9.4.1. Configurations and their applications cannot use same name

Due to current limitations in Connext DDS’s XML Parser, the name of the Web Integration Service configuration tag and the name of the applications within that configuration cannot be the same. For example:

<web_integration_service name="ShapesDemo">
    <application name="ShapesDemo"/>

To workaround this limitation, use different names for the service configuration tag and the applications within. For example:

<web_integration_service name="ShapesDemo">
    <application name="ShapesDemoApplication"/>
