Can not connect to registered odata service after SMP 3.0 server restart

Hi All,

I found a issue in my SMP3.0 server, maybe It is an BUG.

First,I had created the OData model by web service, and deployed the OData implementation project to SMP 3.0 successfully.

Then I could found the registered service in gateway management cockpit, and It can be actived successfully.

Data list:

From the pic,I found the SMP server works fine.

Buf when I restart the SMP server and then open the service document, the SMP server throws the NullPointException.

Who come across this problem ?

Thank you.
