Hello, I am trying to implement the heatMap Field and I have followed the widgets code to the letter. But when I open the form of heatmapFieldForm I have this following error

Hi Amdy

- Have you added the required NPM modules for the Heatmap widget to your package.json (please post your package.json here)?
- Did you execute (p)npm install after you've made changes to the package.json?
- Is the watcher process, which executes the NPM build running? Are there any errors in the console of the watcher process?

Cheers
André

Hi,

The exception is telling you, that it cannot find the object HeatmapFieldAdapter in the default namespace, which is the scout namespace.
The namespace for your app is defined in your index.js on the bottom.

window.yourNamespace = Object.assign(window.yourNamespace  || {}, self);

When creating a new object, the namespace has to be provided. This includes the JsonAdapters. So you probably need to adjust the objectType in JsonHeatmapField and prepend your namespace to the widget name.

@Override
public String getObjectType() {
  return "yourNamespace.HeatmapField";
}

The heatmap example of the widgets app uses the default scout namespace, which is actually not good practice. It is fixed now: Commit.
