ASF GitHub Bot commented on BROOKLYN-433:
-----------------------------------------

Github user aledsage commented on the issue:

    @tbouron It's validated server-side. Longer term, we should improve the validation errors + warnings that the server-side sends back, along with the info needed for content-assist. That's a bigger topic!
    
    @bostko thanks for comments - addressed, rebased and pushed. Once jenkins build completes again, I'll merge it.

> One can specify constraints on a config key's value, to give a validation error if an invalid value is supplied.
> In the Java code, this can be any predicate.
> However, in YAML we don't support many options. It would be good to support a regex constraint. For example:
> {noformat}
> brooklyn.parameters:
> - name: address
>   type: string
>   constraints:
>   - required
>   - regex: ^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$
> {noformat}
> See docs at https://raw.githubusercontent.com/apache/brooklyn-docs/master/guide/yaml/yaml-reference.md, and code at https://github.com/apache/brooklyn-server/blob/master/core/src/main/java/org/apache/brooklyn/core/objs/BasicSpecParameter.java#L204-L205
