I have a also encountered this problem many time, and haven't found any
reasonable way of doing it in JSF other than getting the value from the drop
down as a query parameter and generating the table data directly from the
getter.
For example:
private List data;
public List getTableData()
{
if (data == null)
{
String selection = getQueryParameter("formData:myDropdown");
// The parameter can be taken from the faces context, I don't remember the
exact code now...
data = myDAO.getTableData(selection);
}
Return data;
}
Hope it helps, or someone else give better solution.
Guy.

Subject: Datatable Filtering
Hello all ,
I need to filter rows of the Datatable depending on the criteria entered by
the user. The criteria is in the form of selectBox right above the
Datatable.
So , after the user enters the criteria and submits the form I capture the
criteria and generate a new query and then load the Datatable with the new
query. This is how I want it to work.
I implemented it already but since my Datatable is loaded in the Apply
Request Values phase, I am not able to read the new values of criteria
before that. I am using immediate="true" and value binding on the selectBox
component.
What is the correct way to do this?? Do I have to use component binding to
get new values of selectBox before the Datatable model reloads or do I need
to push Datatable model reloading to the UpdateModel phase.
I am using Request scope all throughout my application.
Thx for the help,
Janap.
