why extendedDataTable-selection in modalPanel cannot catch?
data display in extendedDataTable, selected the data and click the contextMenu excute the takeSelection(), then open the modalPanel, click the a4j:commandButton 'yes' then
call removeSelected .But in removeSelected function get the selection size is 0, what is wrong ?
