I have a combobox with aprox. 3500 items.
There was no performance problem with Swing.
Now with RISC, the list takes about 15 seconds to appear after having pressed the arrow button to display the list.
Is there a possibility to get here an acceptable performance?
...the Combobox-List is created without performance tuning because the number of items is expected to be quite low. So all items are rendered out immediately - there is no e.g. buffering (render only these ones which are visible).
To be honest: we do not plan to update this because your scenario is rather exceptional - and because we provide the COMBOFIELD which delivers similar functions but with much more possibilities for adequate mass processing (server side scrolling, search, ...).
