Quick question around timer nodes, I've done a search on the topics and read the Developerworks article but I can't find an answer to this question.

I've got a flow that is invoked by a timer node every 30 seconds.

If the flow is still running after 30 seconds, will a new instance of the flow be started OR will it fail to start.

Bren,

This question was asked on here about a month ago (but I cant remember by whom).

From memory, the answer was that another instance of the flow would not be invoked while the other flow instance was still running.

You could of course knock up a simple flow to prove this for yourself (with a trace node after the Timeout node and a JCN that just does a Thread.sleep() after that with a value greater than the timeout period).

Cheers,

I was going to put together a proof of concept flow, but it seems to be clear now from that article.
