After upgrading from 12.2 to 12.3 (same behavior on 21.x), while being on the menu Executions and expanding some Tasks, like Workflows - Subworflows - Jobs or Events, like below:
And for example we display the Report of one of the sub-tasks, like below:
While we click on the Return Arrow (in AWI 12.3) or the Return button in the Browser (in AWI 21.x or superior), the expanded tasks are not kept and we need to expand them all again, like below:
The same occurs on the Workflow Monitor and also while observing the Executions of Time Events while clicking on the button Refresh the expanded items are again collapsed automatically.
Release : 12.3, 21.x and superior
Component: Automic Web Interface (AWI)
This is a known limitation valid for all elements with child executions and it was introduced during the redesign of AWI from version 12.2 to version 12.3
From version 12.3 a different UI component is used for the display.
For performance reasons (re-fetching of expanded child tasks from backend) this was deliberately disabled.
That's why every refresh or return to the previous page collapses the already expanded list.
Opening the Report on a new Tab (middle mouse click) allows to keep the Browser Tab from Executions with the expanded list, that way the expanded list won't be lost.
