Please post the stack trace so we can take a look.

Also, why are you disposing of the data set as opposed to closing it?

OK, to explain. I hav a JdesktopPane with JMenuBar. When a user clicks 
something in a JMenu, jInternalFrame is opening with two jdbTables in which 
are data returned from two queryDataSets who are in master/detail 
relationship.

    So, when user clicks the menuItem code is like this:

        <code>public void jMenuItem2_actionPerformed(ActionEvent e) {
        try {
            sifknj = 60;
            Dokumenti_Frame fr = new Dokumenti_Frame();
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(this, "Gre�ka: " + 
String.valueOf(ex),
                                          "Gre�ka", 0);
        }

    }</code>

    Then in Dokumenti_Frame the query is generated on the base of sifknj 
variable and qeryDataSets are refreshed.

    Now when I called
            if (queryDataSet1.isOpen)
                queryDataSet1.close();
    after clicking on jMenuItem, I got the same erorr: Failure notifying 
dependent components of a DataSet reopen.

    Then I added DBDisposeMonitor and the result is ok the first two times I 
click on JMenuItem, but the third time same erorr.
    Here is the stack trace:

That code suggests to me that you're not removing the listeners properly.  
The previous instances of the frames are still there in memory with 
listeners on the query data set.  Managing listeners whose sources survive 
the destruction of the destinations can be quite tricky.  Make sure you're 
using "remove..Listener" when closing your dependent frame.
