Managing of data in a field

The method allows you to clear the filter on the App type field.

 Context.fields.app_type.data.clearFilter();

The method allows you to set a filter on an arbitrary app field.

Important: The method sets a filter at the field level, not for the current form or business process. If filtering is no longer needed, use clearFilter. The method takes a function as an argument, which accepts CollFilterClosure. In FilterClosure you have access to the fileds of an arbitrary app, current context (e.g. of a business process), and global filter functions In the example below:

• refItemFields is the arbitrary app fields;
• context is the current context;
• globalFilters is the global filter functions.

  Context.fields.app_type.data. setFilter((refItemFields, context, globalFilters) => globalFilters.and(
     refItemFields.namespace.eq('my_namespace'), 
     refItemFields.code. eq(context.code) 
  ));
