Hey community,
It seems that since the release of Core extension 3.1+ in Adobe Launch, our code to retrieve a property of "event.detail" does not work.
We used to create a Data Element of type "Javascript Variable" with "event.detail.myproperty". Now it seems that a "Javascript Variable" no longer has access to the "event" object. Probably replaced by the new "Runtime Environment" (I guess for performance??).
To fix this, we created a Custom Code that tests the object and returns the property. At least this still has "event" access.
However, this seems to be a less elegant solution than before.
How would I elegantly retrieve a property of "event.detail" using the new "Runtime Environment"?
Using "Event Detail Payload" only returns "event.detail", and it does not provide a flexible way to read properties (in my case 'event.detail' is an object, and not a string or a decimal).
Solved! Go to Solution.

Generally, if you want to use event.detail.myProperty, where event.detail was set by a Custom Event browser event, then you can use it directly in your Rule's conditions and actions directly, without needing a separate data element.
E.g. in a Value Comparison condition, you can use
%event.detail.myProperty%
equals
foobar
E.g. in a Adobe Analytics Set Variables action, you can use in Custom Code:
s.eVar3 = event.detail.myProperty
The above will work even when you don't have an explicit Data Element called "event.detail.myProperty".
Hi,
As far as I am aware data elements never had access to the `event`. The `event` is sent to conditions and action modules. The JavaScript data element reads the values from the `window` object. When you create a JavaScript data element with `event.detail.myproperty`, it is translated to `window.event.detail.myproperty`. Are you sure you didn't have maybe a piece of code that was setting the `window.event` property?
UPDATE: I was wrong, it seems data elements modules have access to the `event`. But JavaScript data elements doesn't use that and the code wasn't changed in 5 years: https://github.com/adobe/reactor-extension-core/blob/master/src/lib/dataElements/javascriptVariable..... I still think there is a possibility that somewhere in the code you were setting `window.event`.

Thanks @stancu and @yuhuisg,
I have found by accident that using %event.detail.myProperty% on an Action like "Adobe Analytics Set Variables" works without creating the Data Element. I thought I was going crazy.
Even if I have created a Data Element with the same name, I guess that Launch is not using the Data Element.
Thanks for explaining that it is the intended outcome!
