Description of problem:
When ordering service catalog created from orchestration template, it is possible to submit such request without filling "Existing Resource Group" or "(or) New Resource Group" fields. That will lead to the error in provisioning. One of these fields should be filled (be mandatory).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Add azure template with resource_group selection field
2.Create Service Dialog from such template
3.Order Orchestration Stack
4.Do not fill in neither "Existing Resource Group" nor "(or) New Resource Group" and fill all the other fields
Request is not created because either of these fields should be filled.
This was discussed in BZ1549216 but wasn't in the bug description itself, so I'm creating a sepatate BZ for that.
Currently the Service Dialogs do not allow for field validation to be conditional, for example field A is required if field B is not populated. This would require and enhancement to the base dialog system to support advanced validation options.
