Referencing on several dynamically created JFrames

Question

Hi,
I've developed an application for managing tour datas of bike computers.
The loaded tours will shown in a JTable as rows.
With double click on a row, the tour editor will opend (another JFrame class). The user can change some values ot the bike tour.
The user has also the possibility to open several instance of the tour edit class - for different tours in the tour table.
My problem is to find out, if the tour edit object is already created for a certain tour entry in the tour table. Instead of creating a new tour edit object, the already opened tour edit object should get the focus.
How can I manage this? My first idea is, to store all open tour edit object in a static hashmap (w/ unique key) inside the tour edit class.
My second problem is, to transfer the changed bike tour object (w/ the bike trackpoints) to the calling object with list of tours. I've a boolean flag to show, that the tour is changed an i've a getTour() methode to pull the actual tour from the tour edit object.
But, how should I say it to the calling app before the tour edit object is disposed.
Thanx for ideas,
Hans

I have done something very similiar to what you are doing; however, without seeing exactly what is triggering your GUI to add text to the text area's it is hard to give you an exact answer.
Just keep in mind that on all events you should be able to get the source component, which would then let you call the getName method of that component. So if a MouseEvent is the trigger for adding text you can get the name like this:
String compName = ((JComponent) mouseEvent.getSource()).getName()
(assuming you set the name of the component when you instantiated it)
(I have some subclasses that are detected at runtime via reflection, each subclass gets a JCheckBox, there can be 0 or more of these subclasses. I used the getSource/setName/getName methods to determine which checkbox was clicked on even though I don't have a named reference to each one)
