Flex Cairngorm - How to update the model without losing focus in Datagrid? -

-

Using Cairnomorum in my Flex project, I have a model that is a bindable to be displayed by a data grid Array keeps the collection. My problem occurs when the model is updated by reply (after the "update" event, from the Java service), because the focus of the datagrid cell has lost focus (scroll status IL is also lost). Therefore, I retrieve the situation before the update, DataGridEvent. With ITEM_FOCUS_IN event: 

  myModel.focusedCell.rowIndex = e.rowIndex; MyModel.focusedCell.columnIndex = e.columnIndex;

But from where to restore these parameters? How to trigger this trigger only when the model is updated?

Thanks in advance.

For information, I have resolved my problem as follows:

After that, we will have to solve a problem with the scroll as explained in the following post:

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
