No, it's not.
With command /joinarena I call stock that open dialog PBMAINMENU.

Код:

PaintballMainMenu(playerid)
{
	new string[128];
	format(string,sizeof(string),"Odaberi arenu\nPaintball Tokeni\nAdmin Menu");
	ShowPlayerDialog(playerid,PBMAINMENU,DIALOG_STYLE_LIST,"Paintball Arena - Main Menu:",string,"Odaberi","Izlaz");
}

Everything works fine in another gamemode
The last command is an example, with command i can open dialogs, but next opening doesnt work
