Description Fred Rolland 2015-11-23 13:11:01 UTC

Description of problem:
When the user delete a template from an export domain , nothing happens and a NullPointerException appears in the log.

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


How reproducible: 100%


Steps to Reproduce:
1.Create a VM template
2.Export the template
3.Delete the template from export domain

Actual results:
Failure to delete the template from export domain

Expected results:
The template is deleted from export domain

Additional info:
If I revert [1] it works OK
It seems that the injection of "backendInternal" is done only after that the constructor is done.
Here in this command it is used in the constructor flow.
