Sorry, but this has me stumped. I have/had a bunch of nodes which were painful for me to maintain and so I made a subflow of them. Heaps easier to roll out updates to them. Rather than having to edit them all, I just edit the subflow and all is sweet. Thing is it isn't. I have most of them devi…

Making the line: x = flow.get("$parent."+name); resolves the problem. At last! Thanks all. And in the bigger picture it should be this: var debug = flow.get("$parent."+device+'_Button_Debug') || false; // if active: true yes?

[image] Trying_to_learn: context.get/set( ) is local to that instance of the iteration of the subflow The same seems valid for flow.get/set (just modify Steves time example and try). But changing it to global you will see they will operate on the same variable that is not kept inside each ins…

(Idiot hat on) Sorry. I'm not getting what you mean. To break it down to the node in the subflow, this is what I have - NOT working: node.warn("Message received"); // for the sake of knowing the message arrived var x = flow.get($parent.test); msg.payload = x; return msg; Though I think line 2…

What they are trying to say is that if you EXPLICITLY name the variable/context (GLobal or Flow) then each time the subflow runs it will only access that named instance - regardless of where you call it from - this would be desireable if the subflow was not called concurrently by many flows. On the…

I appreciate the reply Craig, but I am still not getting it. I have (again keeping it in line with what is already said) in the flow I set a flow variable test to something. (String) At any time the sub-flow is called and needs to get the value of test from the parent flow. But I am still not s…

[image] Trying_to_learn: But I am still not seeing a working way of doing this Just to be clearer, that is something I did not respond to, I do not know how you can grab flow data from the parent. Only thing I noticed during my tests is that you can get global data in the same way as usual bu…

No problems. I'm not saying you had to answer. I'm just confused that I have read how to do it, but what is written doesn't work, or: I am doing something wrong. Just looking for what the correct way of doing it is.

[image] Trying_to_learn: var x = flow.get($parent.test); Not sure where this comes from, but I can imagine that a subflow is not part of the flow it is living in (it's in its' own little world), in terms of context. Instead of trying to read the flow variable in the subflow, why not just inj…

Assuming to you want to access the flow context variable called test in the flow containing your subflow instance node, then var x = flow.get($parent.test); Should be var x = flow.get("$parent.test")

[image] Trying_to_learn: Though I think line 2 is the problem. You need quotes around the text otherwise it thinks $parent2.test is a local variable it needs to evaluate and already not the value of a variable. [{"id":"a11d54.726bd2b","type":"subflow","name":"Subflow 1","info":"","in":[{"x":…
