Help me!

Feature(s) impacted

Smart action form field when setting type “Collection”.

Observed behavior

I tried to set the id as the value of the “Collection” form field. But it looks like I’m not doing the right thing. I also look for examples on the NodeJS agent documentation but I couldn’t find one.

{
        type: 'Collection',
        collectionName: 'ModelTemplateFamily',
        label: 'Family',
        defaultValue: async context =>
          (await context.getRecord(['familyId'])).familyId,
},

Expected behavior

Fill the form “Collection” field with a default value.

From memory, I think this may be due to the fact that the agent expects an array.

Can you try like this?

defaultValue: async context => [await context.getRecord(['familyId'])).familyId],

This was coded like this to make it possible to handle composite ids, but is clearly counter intuitive.

If that works, I’ll add a ticket to either improve the doc or improve the API (or at least, throw a proper error…)
