Current component (called TreeGrid) provided by Flex Lib
could only accept one
dataProvider as ArrayCollection (No problem with that).
But! I need two show columns each one of them has its own
childs (here is the problem). In my case, I have two columns
(called Requirement1 and Requirement2). And each requirement has a
set of childs (id, sentence, actor, ...).
Actually, it shows a set of relationship between requirement1
and requirement2, and in current version DataGrid shows only
the id number for the two comparison requirements. And the
details for the two requirements will be shown outside DataGrid.
When I saw TreeGrid, I thought that, it will be great to show
the details inside DataGrid itself.
I have tried to wrappe TreeGrid Items ArrayCollection inside
another class as the following:
public var treeGridItems1: ArrayCollection;
public var treeGridItems2: ArrayCollection;
