> Parameterized collection name fails with dynamic params

> Key: NIFI-5305
> URL: https://issues.apache.org/jira/browse/NIFI-5305
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.6.0
> Reporter: Luis M Calderon
> Assignee: Mike Thomsen
> Priority: Major
> Attachments: getmongo_error.txt
>
>
> When using a dynamic property for collection name, the creation of the full
> query reference name is not working as expected. The reference name seems to
> be the concatenation of the namespace and collection name. i.e.
> _<namespace>.<collection_name>)_
> The following parameters are those which are provided to the GetMongo
> Processor:
> Param Definitions:
> my_schema = 'my_schema'
> collection_name = <dynamic value from a FlowFile attribute>
> {code:java}
> Mongo Database Name: ${my_schema}
> Mongo Collection Name: ${collection_name}{code}
>
> Attached is a text file containing the NiFi log for this error.
>
> _There is no namespace error when the same values are hard coded._
