Bug 1802411

Created attachment 1662872 [details]
shrunk dialog box

Description of problem:

When I make a network and subnet by the dialog box in the horizon dashboard, the box becomes something wrong (see attachments) if I submit wrong values in the “Allocation Pools” area then press the “Next” button.

After that, an error message (ie “Start address is larger than end address(value=x.x.x.x,x.x.x.x)”) shows up which is expected. However, I also can press the “Next” button even if it’s disabled. After pressing the disabled “Next” button, the box gets shrunk (“Enable DHCP”, “Allocation Pools”, “DNS Name Servers” and “Host Routes” areas disappear).

Then, I press the “Back” button and press the “Next” button again to move to the “Subnet Details” tab, “Create” button shows up strangely. And, I press the “Create” button, a network and subnet are created without DHCP and specified Allocation Pools. This should be a wrong behavior.

Version-Release number of selected component (if applicable):
 13(Queens) at least


How reproducible:
 Always

Steps to Reproduce:

1. Access http://HORIZON-SERVER/dashboard/project/networks/
2. Press “Create Network”
3. Enter “Network Name” in the “Network” tab, “Subnet Name”, “Network Address” in the “Subnet” tab whatever you want. Then enter a wrong “Allocation Pools” in the “Subnet Details” tab and press the “Create” button.
4. An error message shows up.
5. Press the disabled “Next” button.
6. The dialog box gets shrunk. (This is weird behavior.)
7. Press the “Back” button in the “Subnet Details” tab, then the “Next” button in the “Subnet” tab again.
8. Press the “Create” button in the “Subnet Details” tab.
9. A network and subnet creation is succeeded.

Actual results:
* The dialog becomes incorrect.
  * The “Create” button works partially. But the dialog is broken after pressing the button.
* An undesirable network is created after pushing the “Create” button. For example, DHCP is disabled, the subnet’s DHCP is disabled and “IP Allocation Pools” is the default setting.

Expected results:
* The dialog should be consistent always.
  * The “Create” button shouldn’t work. It should be disabled when the value is incorrect.
* Correct values should be applied or just raise an error at first.
