Lost Variable: please return to owner.....
Hi,
I am having a problem passing data between jsp pages.
My first JSP page contains a table view (5 lines visible data) which uses the onCellClick event to pass data throught on a second jsp page.
However if I page down in the table and then trigger then onCellClick event (say by clicking on line 7) when I get to the second page the data I see is for line 2 (i.e. as if I had never paged down.
My code for the navigation event and onCellClick is shown below...
I have printed out the value of the method getVisibleFirstRow on the first (calling) jsp and it is updated correctly, but when I print it out on the jsp it is always equal to 1.
Any ideas would be appreciated..
Many Thanks.
public void onMyOnNavigate(Event event) throws PageException {
TableNavigationEvent tne = (TableNavigationEvent) event;
if (myBean != null) {
myBean.setVisibleFirstRow(new Integer(tne.getFirstVisibleRowAfter()).toString());
}
}
public void onMyOnCellClick(Event event) throws PageException {
TableCellClickEvent tcce = (TableCellClickEvent) event;
myBean.setClickedCell(tcce.getVisibleRowIndex(), tcce.getVisibleColIndex());
int realSelectedRow = tcce.getVisibleRowIndex() + Integer.parseInt(myBean.getVisibleFirstRow()) - 1;
int realSelectedColumn = tcce.getVisibleColIndex();
myBean.setClickedCellData(myBean.getModel().getValueAt(realSelectedRow, realSelectedColumn).toString());
display = NEXT;
}
I also had trouble with this, but got it to work. One thing you should verify is if the method onMyOnNavigate is actually getting called when you navigate. I did it a little differently. I didn't try to keep track of the visible first row in a bean. I went directly to the TableView to get that value. As follows:
TableCellClickEvent tcce = (TableCellClickEvent) event;
TableViewEventData tved = (TableViewEventData) tcce.getModifierData();
TableView tableView = (TableView) this.getComponentByName("table");
int row = tableView.getVisibleFirstRow() + tved.getRow() - 1;tved.getRow() will give you the selected row. In your example that would be 2. First visible row would be 5. So row will be 7.
