[flexcoders] ComboBox cell renderer is not working in a hierarchical datagrid [1 Attachment]

[Patricia Han]

Hi Friends,

I am trying to create a hierarchical AdvancedDataGrid with a column which is a
ComboBox renderer. I used this renderer in other table which is not a
hierarchical one and it works perfect. But in the hierarchical data grid, for
some reason the combobox is not working. Attached is a screen shot of the panel 
(the last column is the one which has the combobox renderer).

I also noticed that the grouping columns also not working in the hierarchical
datagrid.

Please let me know if you have any suggestions. Thanks a lot in advance.

Here's the source code,


[Bindable]
            private var
hierarchicalTablData:Object =
           
{chassis_card:"Chassis-lab", Summary:"true", children: new
ArrayCollection([
            {chassis_card: "Card1",
s_capacity:"700MB", target:"chs1/card1",children: new
ArrayCollection([
            {chassis_card:
"100MBvNIC", Summary:"true", cardType:"1GB",
s_capacity:"100MB"},
            {chassis_card:
"200MBvNIC", cardType:"1GB",
s_capacity:"200MB"}])},
            
           
{chassis_card:"Card2", 
s_capacity:"400MB",target:"chs1/card1",Summary:"false",
children: new ArrayCollection([
           
{chassis_card:"100MBvNIC", cardType:"1GB",
s_capacity:"100MB",  attributes:"Read Only"},
            {chassis_card:"500MBvNIC",
