Flex 3: should I provide prepared data to my component or make it to process data before display?
- by grapkulec
I'm starting to learn a little Flex just for fun and maybe to prove that I still can learn something new :) I have some idea for a project and one of its parts is a tree component which could display data in different ways depending on configuration.
The idea
There is list of objects having properties like id, date, time, name, description. And sometimes list should be displayed like this:
first level: date
second level: time
third level: name
and sometimes like this:
first level: year
second level: month
third level: day
fourth level: time and name
By level I mean level of nesting of course. So, we can have years, that have months, that have days, that have hours and so forth.
The problem
What could be the best way to do it? I mean, should I prepare data for different ways of nesting outside of component or even outside of flex? I can do it at web service level in C# where I plan to have database access layer and send to flex nice and ready to display XML or array of objects. But I wonder if that won't cause additional and maybe unneccessary network traffic.
I tried to hack some code in my component to convert my data objects into XML or ArrayCollection but I don't know enough of Flex and got stuck on elimination of duplicates or getting specific data by some key value. Usually to do such things I have STL with maps, sets and vectors and I find Flex arrays and even Dictionary a little bit confusing (I've read language reference and googled without any significant luck).
The question
So, to sum things up: should I give my tree component data prepared just for chosen type of display or should I try to do it internally inside component (or some helper class written in ActionScript)?
