I need your help to understand and fix this problem:
I built an apex text class in a sandbox environment (i'm using eclipse) but when I run this apex test class I'm getting this error: System.QueryException: List has no rows for assignment to SObject. The problem is that the object really has records both in sandbox and in production environment !!!! I run that query in Force.com Explorer, salesforce.shema Explorer, etc. and there I can see the existing records but in the test all the time throws that error... Could anyone please guide me why is it happening and how can it be fixed?
Am unable to refresh any of the resources in the IDE from the server.
When am trying to refresh a page from the web, getting an Exception saying:
Unable to refresh resource 'MileaeExension.cls':
com.salesforce.ide.api.metadata.types.Metadata$JaxbAccessorF_fullName cannot be cast to com.sun.xml.bind.v2.runtime.reflect.Accessor
Please assist to rectify the issue.
Thanks in advance,
