Subject: RE: Selecting checkboxes in the backing bean
You are right on the coupling UI and data model. I found it more clean. Make sure the property is transient only for UI. :-)

Assuming, UserInfo is the member class of the collection (datamodel), why should a property exist on it, that is something to do with the presentation on the UI. It actually is not a property of the class at all. I think this would mean we couple UI and model tightly.Therefore, on the backing bean, I have a class level variable UISelectBoolean selected as specified by Craig in this forum http://forum.java.sun.com/thread.jspa?forumID=427&threadID=486654 . This variable is bounded to the Checkbox. As per my understanding, the dataTable internally handles the state of each checkbox mapped to this variable.However, on my code I loop through the rows displayed and set the selected.setSelected(true). However, this doesnt seem to have any effect at all.Note:"table" here refers to an instance of UITable that is binded to the DataTable.int firstRow = table.getFirst();
int numRows = table.getRows();
for (int index = firstRow; index < (firstRow + numRows); index++)
{
table.setRowIndex( index );selected.setSelected(true);
}ThanksBala-----Original Message-----

I have a page where there is a SelectOneMenu and a dataTable beneath. I would like to select a couple of rows in the dataTable based on the selection of the SelectOneMenu.
I have registered a ValueChangeListener to the SelectOneMenu and my method is getting called.
But how do I actually check the CheckBoxes created in the DataTable programatically based on one of the column information. Assuming I have a colum called name, and I have to select all the rows containing the name "XXX", how would I get a handle to the column rows and the checkboxes to select it.
Is looping through the UIViewRoot, the only way?
Does anyone have any ideas?
Thanks
Balaji
