[Closed] Dock UI does not create new tab next to command panel

Hi all,

I’m forcing my UI to be docked to the right on open. What I get is this:

However, what I’m looking for is this:

Code snippet to create rollout:

createDialog ExporterRollout menu:(ExporterStruct.mainMenu())
cui.RegisterDialogBar ExporterRollout style:#(#cui_dock_right,#cui_floatable)
cui.DockDialogBar ExporterRollout #cui_dock_right

Any ideas what I can do so that on launch it docks to the right where the command panel exists, thereby creating a new tab?

Thanks for the help.
