I think these two are different defects. In this defect, we are solving the problem that when adding a logical pool with the right "Storage Pool Name" 
as well as selected "Device Path", Clicking on "Create" and a warn message box showed up. Now you click on cancel or the "X" that you regret creating the storage, 
the inputbox of "Storage Pool Name" and the "Create" button is still disabled. Though Bug#457 has been fixed, this issue still exists and this patch is used to fix this. 

Isn't this the Github issue #457? It seems to be already closed.
