Different behaviour while working with project task on Project Worskpace and Classic UIIssue While working with Project Tasks in Project Workspace and Classic UI, you might see scenarios where it behaves differently. For example, when creating a Project Task in the Classic UI and changing the Planned end date field, it instantly updates the Planned duration with the calculation between the Planned start date and Planned end date. The same action on Project Workspace will only happen if the user clicks outside of the task being edited.ReleaseAll supported releases.CauseThis behaviour is expected. In Classic UI, it uses a combination of records to do the calculation using the onChange trigger. In Project Workspace, it will only apply the calculations (and additional processing activities) when the user clicks outside of the row. This way, the system understands that the editing of the row is completed, and it will perform the expected actions.ResolutionThe Project Workspace is a modern UI which gives flexibility to create tasks in a fast way compared to classic forms, and it waits for the user to finish the inputs to do the next steps. Once the user finishes, click outside of the task so it will perform the next actions, like calculating dates and saving.
