Description Flags

Description shani 2017-11-02 09:15:35 UTC 
Created attachment 1346922 [details]
An empty cause while trying to retrieve an image list.

Description of problem:
In case of catching an exception while trying to view an image list, and that exception has a null cause, the following error message appears on engine.log:
ERROR [org.ovirt.engine.core.bll.storage.repoimage.GetImagesListQuery] (default task-3) [a07a2682-7ad1-463d-aadb-743bca86a0e6] Failed to retrieve image list:  
In that case, instead of representing an empty error message, the exception's message should be presented (and not an empty cause). 

Version-Release number of selected component (if applicable):
4.2.0

How reproducible:
In case the exception.getCause() returns null - 100%

Steps to Reproduce:
1. Create an external storage provider
2. Goto storage domains -> choose <your_new_storage_provider_name> storage domain -> images tab
3. In case of failure on loading the image list, see the engine.log

Actual results:
ERROR [..] Failed to retrieve image list:  

Expected results:
ERROR [..] Failed to retrieve image list: <the exception's message>
