How do I select a feature in a cluster

[panchofrank]

Hello,

I'm trying to programmatically select a feature that is in a cluster: https://jsfiddle.net/Francoisgaudin/2bxdjuwg/

When I select the feature by clicking on it we see that the feature appears in an array as a field in another feature. I guess that other feature represents the cluster and it has a generated id. When we enter that ID in the jsfiddle text box and attempt to select by pressing the button nothing happens.
Also I can't find the cluster features using a getFeatures call on the source of the layer.
What am I doing wrong?

So I manage to do the selection with the following call:

this.$refs.interaction.select(this.$refs.clusterLayer.getSourceTarget().values_.source.getFeatures()[0])

Is there a more concise way to the feature?

Hello @panchofrank ,
your fiddle is how it should work, but for now vl-source-cluster a bit buggy.
I see 3 problems with it:

• id dynamically generated 2 times for same cluster, so you can't get correct id
• vl-source-cluster doesn't allow generate cluster properties by some user defined handler
• vl-source-cluster doesn't emit update:features event like vl-source-vector, so you can't listen for clustered features changes

I'll try to release patch as soon as possible.
Thanks for pointing me to this problems!

@ghettovoice Hi! How are you? I am working on a map which I need to show the elements grouped by cluster, but I must also show the lines that join the points (LineString) only when the points are visible and not grouped

Hi @alejandrosuarez231 ,
I don't actually know what you want to implement.
But I think this very basic example should show you an idea to use dynamic linestrings layer
