Hi Chandra,
maybe it is hellpful to know, why I need this event.
There is a control (custom control, no SAPUI5 at all) which calculates its dimensions once and uses fixed pixel widths and heights. However, I need this custom control to re-render after the pane is open, so the control changes its width accordingly.
An onAfterPaneWasOpened event would be the best fit.
Regards
Tobias
