scrollableDataTable java.lang.NumberFormatException
Hi
get to the point
xhtml code
<rich:scrollableDataTable id="selectSheetContent" binding="#{upload.sheetTable}"/>
java code
sheetTable.setRows(40);
sheetTable.setFrozenColCount(1);
sheetTable.setHideWhenScrolling(true);
sheetTable.setValue(table);
sheetTable.setVar("item");
for (int colNum = 0; colNum < columnCount; colNum++) {
HtmlColumn column = new HtmlColumn();
column.setId("column_" + colNum); //------------column_0
HtmlOutputText head = new HtmlOutputText();
head.setValue("ColumnLabel" + (colNum + 1));
column.getFacets().put("header", head);
HtmlOutputText cellContent = new HtmlOutputText();
cellContent.setValueExpression("value", Expressions.instance()
.createValueExpression("#{item[" + colNum + "]}")
.toUnifiedValueExpression());
column.getChildren().add(cellContent);
sheetTable.getChildren().add(column);
}
the table can be shown, but when I click the column header:
in IE7, nothing changed
in IE6, jump to the error page
and in the console, throw java.lang.NumberFormatException
