[ANGULAR] How to obtain expanded tasks？

[lanpeng]

Hi bryntum team
I want to obtain all the expanded tasks after user click save button, But i found that the expanded property of the tasks has always been the original data of the task, even if the user clicks the expand icon button and expanded the task.
I uploaded a test case, could you help me check it.

As a tree node can be part of multiple stores, you should query for this:

task.isExpanded(gantt.taskStore)
