Moving Aggregator + Group Loop Start error - window length

[gonhaddock]

Hello @jordanrweil
I wouldn’t imagine windows length n=1 looking your captures…
In this case you have to aggregate an ‘IF Switch’ node. Aiming to bypass the Moving Aggregator in the case n=1.

You will need to add a ‘Rule Engine Variable’ node too, aiming to handle the chose port of the ‘IF Switch’. And an ‘End IF’ node concatenating the bypass flow after the ‘Moving Aggregation’…

In this forum topic there is an sketch showing how to implement a similar case to your use case.

Bypass metanode or component

Hello, Empty Table Switch is a good solution if you only have to handle empty tables. If you have to handly more complex states you can control the If Switch Node with a Rule Engine Variable. If your conditions are true then use the “top” output of the If Switch otherwise the “bottom” output. Of course you can nest these switches. [image] My content of the Rule Engine Variable Node looks like this [image] Please note that the If Switch Node needs case sensitive input! “bottom” and “top” …

The code that you need for your ‘chose_port’ variable could be like this one (being bottom port the bypass flow):

$${INumber Rows}$$ < 2 => "bottom"
$${INumber Rows}$$ >= 2 => "top"

I hope you can fully execute all loop iterations with these additions.
