cdk-sns-topic-export-import

This demonstates an issue I am having with implicit exports and imports. Basically a refernce to a resource from another stack in a property override does not seem to trigger the import.

2019-03-14T1732-0600: Added branch workaround1 which shows a potential work-around. Feedback welcome.

sns-topic-stack

Contains a single sns.Topic resource that it implicitly exports via public readonly snsTopic

dependent1-stack

Implicitly imports the SNS topic by referring to it in a codedeploy.CfnDeploymentGroup

works

dependent2-stack

Implicity attempts to import the SNS topic by referring to it in a property override of an codedeploy.ServerDeploymentGroup

does not work

Does not actually import the SNS topic

dependent3-stack

Combines dependent1 and 2 stacks above. The reference in a property override works because the import is triggered by its presence in the codedeploy.CfnDeploymentGroup.

works
