Arpad Boda commented on MINIFICPP-985:
--------------------------------------
[~phrocker] theoretically we could in property as there is a collection mode of
properties, where this could be done, although:
-This isn't exposed to the test framework, we can't even verify
-This member of properties are not part of the agent manifest, so it's
impossible via C2. Also setting multiple values would require changes in C2
communication.
-Even if we fix the above two, ListValidators provide more, like a property can
be a set of integers. In this case we can't list allowable values, but Integer
validator is not enough to cover this.
What you mentioned (4 and 3.3) is something I definitely DON'T plan to support
this way, only multiple values of one type, where the validation doesn't become
complex: just tokenising the value and validating the tokens using one
encapsulated validator. I think it's very low risk and low impact (~15 lines of
new code + tests),

> Key: MINIFICPP-985
> URL: https://issues.apache.org/jira/browse/MINIFICPP-985
> Project: Apache NiFi MiNiFi C++
> Issue Type: New Feature
> Affects Versions: 0.6.0
> Reporter: Arpad Boda
> Assignee: Arpad Boda
> Priority: Major
> Fix For: 0.7.0
>
>
> As [~nghiaxlee] pointed out in a change we don't have the functionality to
> create list validators (in which case all elements of the input lists should
> be validated using an encapsulated validator), so we can't validate multiple
> choice properties for eg.
> The change itself is quite easy, although we should keep in mind C2
> integration. Because of this [~phrocker] and [~kdoran] I would like to ask
> for your feedback on adding this into agent manifest. Thanks in advance!
> I scoped this for 0.7.0 as the MiNiFi impact would be small, however I can
> accept rescheduling it to 0.8.0 in case C2 integration requires more effort
> and testing.
