Description of problem:
The Refresh button on my Dynamic Dropdown Lists runs the method which uses "nil" as hash key cause UI to hang with
the waiting wheel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create a custom dialog with a Dynamic Dropdown List and a Refresh button
2. Create a method that is call when hiting refresh, use "nil" as hash key the method
3. Call the dialog from a service provisioning or custom button
4. Click on "Refresh"
The UI hangs.
The UI is refreshed with the "dialog_field" generate in the method.
Using an empty string instead of nil as hash key solves the problem, this bugzila is opened to support "nil" .
