Scrollpositon of KM Navigation iView tree

Hi all,

we have a project for a PDF reporting system based on KM with EP 7.0 SP29.

For this system we use taxonomies to place the PDFs into the correct folder.

The different folders are displayed by an KM Navigation iView with a

TreePreviewLayout.

Now our problem is, that with the many different folders a scrollbar is needed

and everytime when the user open a folder at the bottom of the tree, the whole

iView is refreshing and after the refresh the top of the tree will be shown. This

is not a practicable solution for the user.

So, does anybody know how to preload the tree or how to keep the scrollpostion ?

Thank you for your help.
