PreviewDiagramScreenActivity failed in OPEN: java.lang.RuntimeException: CDI Event exception: CommandType=CDIEvent, BeanType=org.kie.workbench.common.stunner.core.client.canvas.event.registration.CanvasElementAddedEvent, BeanReference=org.kie.workbench.common.stunner.core.client.canvas.event.registration.CanvasElementAddedEvent@cc23, FromClient=1 sent to [unavailable]

We are lacking the support for "Boxed List" semantic, as described page 107 here : https://www.omg.org/spec/DMN/1.2/PDF

The boxed list are represented by separate grid, similar to the Relation grid, however there is single column and no header cell. Other cells can be literal expressions or contexts.

Manual acceptance test

• Build a deploy model containing List expression
• Run in Test Scenario a model containing List expression we need to agree if list should be set via collection editor
• Change existing expression to List
• Open attached model of reporter
• Open third party model
• Documentation
• Data Type just Collection not able to find n specification, what should be type of decision node with List inside
• Access item of list in dependent decision
• 100+ rows few times error throw when scrolled and start edit, but can not find stable way to reproduce
• List Entry, Clear and change type clear-expression.webm
