<pre wrap="">Hi forks,
I have a trouble on datacombobox performance.
I use some own components that is extended with datacombobox.
The attachment is the sample.
You can see how slow binding data in datacombobox.
This is a tiny code but it take over 1 second to bind data.
In fact, i use a ton of datacombobox in a view, so this *slow binding*
became big trouble on my apps.
Are there any workaround of it ?
It works on below environment.
Windows XP, Pen4 2GHz, 2GBmem
OL3.3.3, FireFox 2.0, Flash Player v9
Thanks,
mt1
