How to get checked rows data from a table?

Question

Hai
For displaying a check box in my table in jspx page,I created a transient Attribute , sel and select type as Boolean.Then When i drag and drop the viewObject in to my jspx page.The table cantain id,Name,Designation,Salary,sel
Then i deleted the binding in the sel column,and drop a Select Boolean checkBox in to that column.Then in the property inspector i bind the value as #{row.sel} for checkbox..
In my table suppose there are 5 rows..I checked only 3 of them.When i pressed a button,the corresponding id 's should be fetched from the checked rows in the table and i want to show some more details corresponding to that id 's in to another table in the jspx page.I am using jdev 11

Hi,
So if I get you correct this time, you do not want to select the rows by clicking on the table row but rather by selecting the checkbox you created. Correct? Sorry, the earlier confusion is due to me "thinking in Trinidad". Anyway, you can then set the table's rowSelection as None, since you won't be selecting the row that way. Try the code below.
public String doSomething() {
    List<Row> rows = getAllRows(getTable1());
    for (Row row : rows) {
        if ((Boolean)row.getAttribute("sel")) {   // Check if it's true which (should) indicate the checkbox as being selected
            System.out.println(row.getAttribute("id"));   // Your selected id based on the checkbox you selected.
public List<Row> getAllRows(RichTable table) {
    List<Row> rowList = new ArrayList<Row>();
    Row row = null;
    FacesCtrlHierNodeBinding rwData = null;
    int total = table.getRowCount();
    for (int i = 0; i < total; i++)  {
        rwData = (FacesCtrlHierNodeBinding)table.getRowData(i);
        if (rwData != null) {
            row = rwData.getRow();
            rowList.add(row);
    return rowList;
}Some points to take note. The getAllRows method loops through the whole VO. So if you have 10,000 rows, it loops 10,000 times. If you are dealing with large records and/or want to optimize the code, you'll need to loop through the "displayed rows" only. For that, you'll need to tweak the code.
