After a new sub-todo is created under some point of the hierarchy it is displayed in the correct position for a short time (maybe 1/2s) and then it, apparently, migrates to the top of the hierarchy as an independent todo. Only after the application is restarted the correct position in the hierarchy is displayed.
Which resource type is your calendar ?
My calendar resource type is localdir. I should say however that I recently upgraded my systems to kontact 4.4.11 on kde 4.8.4 and the problem seems to had gone away. Thanks for your care
Right, this was fixed in 4.7, thanks.
