 Description   

I tried to POST xml files from integration test suite. I randomly ran into error described in next text. When I try to POST same data right away after receiving error POST succeeds. I was not able to trace any log data in karaf.log. This seems to be one of reasons of failing robot tests.

martin@ncc1701e:~/programs/odlRestyScripts$ POST < /integration/test/csit/variables/xmls//f7.xml
{"errors":{"error":[

{"error-type":"application","error-tag":"operation-failed","error-message":"Error creating data"}

]}}
martin@ncc1701e:~/programs/odlRestyScripts$ POST < /integration/test/csit/variables/xmls//f9.xml
{"errors":{"error":[

{"error-type":"application","error-tag":"operation-failed","error-message":"Error creating data"}

]}}
martin@ncc1701e:~/programs/odlRestyScripts$ POST < /integration/test/csit/variables/xmls//f11.xml
{"errors":{"error":[

{"error-type":"application","error-tag":"operation-failed","error-message":"Error creating data"}

]}}

URL to which I posted data is : http://localhost:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/2/

I've added patch for a deep logging in restconf:

I tried with the integration f7 xml and am consistently getting the Error.

There is an exception during parsing of the flow xml. I have attached the exception log.

I have used the openflowplugin-all-li (lithium) feature to install on a single node setup.

Anyway this does not seem to be related to clustering/datastore.

Please ignore the above analysis. Got some errors with the url.

Comment by Kamal Rameshan [ 12/May/15 ]

Unable to reproduce.

I posted all the flow xmls form the integration/test/csit/variables/xmls/ folder, in loop within a script.

And all the flows could be found both in config and in operational.
