Different onMouseOver Event for each row of a report

Question

Hi all,
See
http://htmldb.oracle.com/pls/otn/f?p=41861:1
As you can see in the demo, all employees of a department are shown when you click the detail link for a department. This is done with the help of AJAX technologie to avoid the submit of the page.
My question is: Is there a possibility to show the the employee report for the correct department when I move the mouse over the row of a department. In other words: what I am searching is a possiblity to define the behaviour of a certain row, so that code like
<tr onMouseOver="javascript:getEmps(1)">....</tr>
<tr onMouseOver="javascript:getEmps(2)">....</tr>
is generated.
Thank you in advance
Stephan

Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.

Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do
