Hi,
problem : users want to select and deselect some columns of dataTable then export result to Excel
solution : i use rich:extendedDataTable that has ability select and deselecting columns of dataTable but unfortunatly after i export it to excel all of columns export, i search in seam code and found this
UIData dataTable = (UIData) FacesContext.getCurrentInstance().getViewRoot().findComponent(dataTableId);
List<javax.faces.component.UIColumn> columns = ExcelComponent.getChildrenOfType(dataTable.getChildren(), javax.faces.component.UIColumn.class);
dataTable.getChildren returns all columns of extendedtable
seam excel exporter returns all columns
is there any way, i can export only selected columns in rich:extendedDataTable to excel?
