As soon as you work with multiple flows you need link-in and link-out nodes to connect.
Unfortunately when doing an export and re-import flows the links are broken which is a challegne when having multiple flows.
Just updated to node-red V1.x but looks like that has not been solved yet.
Is there any workaround to solve this problem?
can you provide a bit more of an example of what you mean?
There was a bug in this area some time ago, although I can't find the details right now. But it is certainly fixed in 1.0.2 as I've just successfully exported and imported a flow that includes link nodes.
