How to copy field from one flow to subsequence flow whose message type is websequence

[shubhamlal]

I need to extract a specific field from the HttpMessage response in the first flow and include it in the params map for the second flow, where the message type is webSequence. How can I implement this?

This is solved through dependency method in Flow via chaining from flow to sink flow methods,
Example

	public static Consumer<Deriver> copy( Flow fromFlow, Transmission.Type fromType, String fromField,
	    String toField ) {
		return ( p) -> {
			p.dependency( fromFlow, ( s ) -> {
				return s.from( _<<Interaction>>_, fromType, fromField )
				    .sink( f -> Flows.interactions( f )
				        .filter( <<Interaction>>).findFirst().orElse( null ),
				        Interaction::request, toField );
			} );
		};
	}
