Bug 537571: [Sequence Diagram] Support Time Observation/Constraint as a node on an eventbugs/536486-timeDurationsOrderings
Fix problems in the location of time elements on lifelines: - failure to refresh after undo moves a message end - time element located on the center of the lifeline head instead of opposite the create message when opening a diagram Change-Id: Ice6a31e9b4bb1e757378494a62a2714d775f47dd Signed-off-by: Christian W.
