Dear Apex gurus
I have been fighting with this server-side condition problem for one day, still can't figure out, thus decide to ask for help.
on the top portion of my page, I have a popup LOV with 5 list options (A, B, C, D, and E) for the 5 regions (A, B, C, D, and E),
my intention is when A option is selected, region A display, other unselected region will remain hidden (I use css to hide all region initially), because each region contains some big charts with a lot of data, I choose to use server-side condition.
however it is not working, after I set server-side condition on a certain region (A for example),
Type --> Item = value
Item --> P24_List
Value --> A
when I select A option in LOV, Region A is not showing, why is that? how can I make it work as intended?
under the p24_list, i have Dynamic actions for each options

Thank you in advance, appreciate if someone can help.
