This is a custom widget that espects a **taskId **and gets you an array of case variables.
The case variables will be accessable by name. Bind the variable and access them like this:
The whole structure of the case variable (see REST API) is kept in the array.
The **taskId **can be easily retrieved by getting the URL parameter.
This widget only works when embedded on a task form (not for living applications, unless you get the taskId from somewhere).
