vim dirdiff autocmd bufenter disturb existence of b:currentDiff

Hi,

Using Vim DirDiff plugin

I have made this vim9 func to set layout and go to next diff.

def g:ManageDirDiff()

  if ( &ft == 'dirdiff' )

  echomsg 'Manage dirdiff'

if &columns < 200

  set columns=999 

  set lines=999

endif

resize 4

windo if &diff | setl nofoldenable | endif

    exec ':1,2 windo vertical resize ' .. (&columns / 2)

    exec ':1,2 windo setl nofoldenable'

    exec ':1,2 windo norm ]c'

  endif

enddef

When I call this def function from mapping it is ok.

When I automate it with this autocmd it disturb dirdiff plugin b:currentDiff variable to be set.

if has("autocmd")

  augroup VimReload

autocmd!

autocmd BufEnter      *.tmp     call g:ManageDirDiff() 

  augroup END

endif

This cause this error message

Manage dirdiff

Error detected while processing function <SNR>77_DirDiff[117]..<SNR>77_DirDiffNext[10]..<SNR>77_DirDiffOpen:
