Description of problem:
(Issue is with NEWER dialog editor)
The default value is not stored for a Dialog of type "Drop Down List" and "Radio button" with value "Integer". This is not a dynamic dialog. 

Version-Release number of selected component (if applicable):
5.9.0.22.20180221205805_f93a675 

How reproducible:
Always

Steps to Reproduce:
1. Create a dialog with type "Drop Down List" and value "Integer"
2. Create 3 entries (1 => 1, 2 => 2, 3 =>3)
3. Set a default value either 1, 2, or 3

Actual results:
The default value is not stored in the dialog. Checked with Radio button and Dropdown by ordering dialogs.

Also noticed that dialog preview screen which is on endpoint '/miq_ae_customization/explorer' works however it does not work while ordering.

Expected results:
The default value should be stored in the dialog.

Additional info:
For type "Radio Button" and "Drop Down List" with value "String" the default value is stored correctly.
