CSV-Export does not work

[CarstenHollmann]

If you try to export to CSV time series of a SOS 2.0 instance that is integrated with a SOAP-adapter the export processing icon rotates but nothing more happens.

The problem is that the SWC sends a POX encoded DescribeSensor request with ContentType text/xml to the SOS although the SOAP adapter is configured. If the SOS does not support POX or the configured SOS URL point to the SOAP endpoint ../soap (52N SOS 4.x), an exception is thrown by the SOS.

Exception log of the SWC:
