placing a color picker on a datagrid

[womblies]

hi all

i have a problem with trying to place a colour picker component in a cell of the datagrid component and show a certain colour that is stored in a database/array.
i can place the CP in the cell of the grid but the problem arises in the preview of the CPin the grid, the value is for the CP in set in actionscript (hex number) but the preview stays black. when i click on the CP the correct colour shows up on the palette. the question is why doesn't the preview show the same colour?

if anyone is not fully sure what i'm saying i can send a sample fla to show the problem more clearly.
