RE: Selecting checkboxes in the backing bean

[Balaji Saranathan]

Title: Message

Hi,

 

Isnt there any other way to do it? 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);
      }

 

Thanks

Bala

Add a property in backing bean data model(member class of collection) such as selected, and bind the checkbox to the property.

Hi,

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
