Data Source is not shown[bug]

Hey everyone,

The purpose is simple. Having two repeating groups, one nested to another get the data from Option Sets. Second, nested group is getting data from attribute, which inhereting data from Option set. And the source to retrieve data is not shown in the list. I double check manual and bubble videos.

Maybe I am doing smt wrong?

I don’t think there’s a bug, I think you didn’t set correctly your data source
Should be Current cell Dashboard pagetab’s chart (or charts 2) as your want to reference the related OS dashboard attributes no?

That is the point. There is no “chart” or “Chart2” in a suggested list.

I understand now. You probably face this Pro Request: Unlock "Incompatible Type" in Elements Dropdown

There’s other topic about workaround
Basically, set the expression you need in a only when for example, copy it and paste it in data source.
