      The DMN boxed expression editor is one of the main components in the DMN editor. It handles a variety of decision logic types, and it has many layers of complexity.

      The current implementation of the boxed expression editor works fine. However, it's a Canvas based component. Even working nicely, it leads to limitations like: I) the HiDPI intermittent issue (DROOLS-5295); II) performance concerns associated with the number of rows (BAPL-1653); III) and the main limitation of not having cells with highlighted FEEL expressions.

      To address these issues, this BAPL comprehends the re-write of the DMN boxed expression component by following the new architectural standards followed by Kogito-based projects.

      The new boxed expression editor component must cover all features already covered by the current implementation:

      • Support for Literal Expressions definition
      • Support for Contexts definition
      • Support for Decision Table definition
      • Support for Relation definition
      • Support for Function definition
      • Support for Invocation definition
      • Support for List definition
      • Keyboard navigation
      • Context menu support for applicable actions
      • Input/Output columns generation based on the type of the input nodes/the type decision node

      Additionally, it must support:

      • Code highlight and code completion on all FEEL based cells
      • Copy/Paste integration with other spreadsheets
      • Support to merged cells

      The new DMN boxed expression component must work as a standalone "stateless" React/TS component. It must communicate to the rest of the editor by a thin JsInterop-based interface to provide boxed expressions definitions for BKMs and Decision Nodes.

      Acceptance criteria:

      • As a user, I want to be able to define Literal Expressions by using the new boxed expression editor
      • As a user, I want to be able to define Contexts by using the new boxed expression editor
      • As a user, I want to be able to define Decision Table by using the new boxed expression editor
      • As a user, I want to be able to define Relation by using the new boxed expression editor
      • As a user, I want to be able to define Function by using the new boxed expression editor
      • As a user, I want to be able to define Invocation by using the new boxed expression editor
      • As a user, I want to be able to define List by using the new boxed expression editor
      • As a user, I want to be able to navigate and edit cells by using the keyboard with shortcuts similar to the "old" boxed expression editor
      • As a user, I want to be able to use the context menu to insert/delete columns
      • As a user, I want to be able to use the context menu to insert/delete rows
      • As a user, I want to be able to use the context menu to duplicate rows
      • As a user, I want to be able to rely on fixed headers and columns (to keep the numbered column and the header row always visible)
      • As a user, I want to be able to have Input/Output columns generation based on the type of the input nodes/the type decision node
      • As a user, I want to be able to see cells with highlighted expressions
      • As a user, I want to be able copy cells from Google Spreadsheets and paste on the boxed expressions grid
      • As a user, I want to be able copy cells from boxed expressions grid and paste on Google Spreadsheets
      • As a user, I want to be able to see cells with the same value merged (like the GDT editor does)
