Re: [Dev] Null pointer exception from api gateway component when logging as the tenant-admin

2015-10-15 Thread Harshan Liyanage 
Hi all,

We have put "synapse" as the gateway type. Changing it to none resolved the
issue. Thanks for the feedback.

 Hi all,

 I'm getting the below exception when logging as the tenant-admin
 (latest EMM build). We are
 using org.wso2.carbon.apimgt.gateway.feature.group version 4.3.0-SNAPSHOT
 at the moment.

 Could please someone from APIM team can shed a light on this issue?

Re: [Dev] Null pointer exception from api gateway component when logging as the tenant-admin

2015-10-14 Thread Uvindra Dias Jayasinha 
Hi Harsha,

This seems to be happening because you dont have the default sequences that
are shipped with the APIM pack. When you login to the tenant for the first
time the sequence are copied over to that tenant space, but you dont have
these in the MDM pack. The Error and Warning above the NPE also shows that
this is the case.

We have not handled the scenario where the gateway feature would be used in
when an actual synapse gateway does not exist. We need to validate the
gateway type and only carry this step out if the gateway type is synapse to
avoid the NPE.

2015-10-14 Thread Amila De Silva 
Hi Uvindra,

IIRC TenantServiceCreator ( the task which deploys synapse artifacts upon a
TenantLoading) is only registered, if the Gateway type is Synapse. If we
 set it to None, then that task should not get registered.

Ok, to confirm what Amila is saying, Harsha can you check the value of the
** element in the api-manager.xml of MDM? The value should be
*None*.
