Setting Flow variable in Template


I have searched over the forum but not find a solution:

In a template node I know how to get the value from a flow variable defined in a function node ,for example:


works well, but to set a flow variable from a template node ?

The documentation says something like that: {{flow[store].name}}

But what value have to be [store] ? For example, if i wish to store the value "100" in "MyValue" is it:

{{flow[100].MyValue}} ? or {{flow["100"].MyValue}} ? What is the good syntax ?

Thanks for your help !

You don't "set" properties in the template node, only read them.
The template node is used to format messages, not to manipulate them.

Ok, thanks
