param type Json badness

[Kevin Fox]

When launching a template that has a parameter with type Json, the cli works, but the Dashboard displays a random other field duplicated rather then displaying the correct parameter, and can not submit properly. Removing the Json type param causes the stack to display and submit properly. Dashboard needs to know how to handle the Json type.

Could you provide some more details about how to reproduce this? When you say "launching a template" are you referring to launching an instance from an image? Can you give the cli command that works? Is there anything specific in the json that causes it to fail?

I'm sorry, I guess that was a big vague. I'm referring to launching a new heat stack using the orchestration section of the dashboard. If the heat template file provided has a parameter with "Type: Json", the dashboard heat ui breaks.

Can you post the heat template that's causing this error?

[Kevin Fox (kevpn)]

Sure. Grab any heat template from the example repo. For example this one:
https://raw.githubusercontent.com/openstack/heat-templates/master/cfn/F17/MySQL_Single_Instance.template

Pick a Parameter and change it to Json. for the example url above:
change Parameters->KeyName->Type from "String" to "Json".

I've done this and attached it.

When the dashboard displays the form, for the heat template, its wrong. In the example, I'm seeing Two "DBRootPassword" boxes and no KeyName boxes now.

I believe the dasboard would work properly if it simply would treat any field that is of Type: Json the same as Type: String.

Here's a screenshot of what I'm seeing.

This may be the same root problem as https://bugs.launchpad.net/horizon/+bug/1360495. The label is incorrectly being duplicated from the entry above. The form does recognize that it is a json field and properly performs json validation against it.
