Re: [rap-dev] DataBindig - performance problems when binding large lists

[Benjamin Muskalla <bmuskalla@xxxxxxxxxxxxxxxxx>]

Hi Dana,

this question belongs better to the newsgroup and in this case to the 
platform newsgroup as they own the Databinding code. I think for a 
better understanding, it would be good if you provide a snippet to show 
the performance bottleneck.

Regards,
 Ben
