I didn't expect this. (And by the way, it is not really a bug, but rather an unexpected behavior of the GUI, I guess).
Suppose I have several subgraphs of a same graph. They all share the viewSelection property of their common parent graph.
Suppose I have views of each of these subgraphs (using the GUI). When selecting nodes and/or edges with the selector tool, the selection affects the parent property: as a result, I can select in one subgrpah and immediately see where theses nodes sit in the other subgraphs. That's quite useful, I tell you.
Now, when running the Reachable Subgraph plugin on one of these subgraph, the result is now stored in a local boolean property. So I don"t get the synchronization effect I got with a manual selection ...
I suggest you to read

In this paragraph you will find how to simply configure Tulip for your need:

"This menu allows to choose the storage policy for the result of property algorithms (such as measures or layout algorithms). When they are applied to a subgraph, this result can be stored:
Yeah, great! Thanks for replying so promptly!
