Show selected List items in table

Hi,

i want to show all selected items  from a multiselect-list in a table. How can i "bind" the 'selectedItems' to another table?

Actually I use a "selectionChange" function to read all selected items and set a filter for each items with witch the table get filtered. Is there a different way? Both, the list and table using the same model.

I hope has some easy solution because my way isn't what i would call "beauty".

Thanks for your help and Happy Easter!
