How can I use a built-in Feature-Action (Zoom, Select etc.) in my JS code?

Question

Particularly, I have a plot with lists of Feature IDs associated with elements of the graph.
I want to be able to zoom the map to the area containing the named features.

More generally, I would pop-up a menu (I know how,) and select 'Zoom, Show/Hide, Highlight, ...) the way the built-in Pie-Chart Widget does.

I cannot find any example or documentation on the subject!

It knows which layer to use because it is associated with the dataSourceProxy which is associated in the configuration.

As my widget has to work with multiple data sources - I have a problem!

Oops, for whatever reason rest of your message wasn't showing...

To get the default action option into the configuration window, include supportDefaultFeatureAction in your widget manifest file under configuration:

...

"configuration": {
    "requireDataSource": true,
    "supportFeatureActions": true,
    "supportDefaultFeatureAction": true,
    "path": "config/myWidgetConfig.html"
  },
  
...

I seem to recall this isn't documented - I think I trialed and errorred it...! Yikes. So I guess I should say use at your own risk!

The WidgetProxy.executeDefaultAction method takes either an array of OBECTIDs or an array of features. It's not clear to me how the system knows which layer the OBJECTIDs belong to, but I haven't used that route at all to see. But the array of features is simply an array of Graphic objects that either you can use from an existing source or create from scratch. So I think that's where you'll utilize your feature list either directly or parsing it into an array (depending on what form it is in to begin with...).

Hopefully that makes sense?
