flex - DataGrid edits label instead of data -

-

i have editable datagrid in flex, data full of numbers. columns have no special itemrenderer, labelfunction, returns number as-is if positive, puts in parentheses if negative, so

27.3 => "27.3" -27.3 => "(27.3)"

now, these cells editable. when try edit cell positive number, nothing wrong. if try edit negative number, starts editing (27.3) instead of editing -27.3. because of this, when edit done, labelfunction evaluated new value in parentheses(i.e., labelfunction called "(30.5)"), , converting number results in nan.

so, want know if can make datagrid edit data in dataprovider instead of label shows.

i hope clear condition. please ask if need clarification.

thank you.

is you're after?
