From class back to main application

[Pmarcoen]

I have a very dumb basic question.

From my main midlet I call upon a class FileSelector as follows :

fileSelector=new FileSelector(this);
display.setCurrent(fileSelector);

Now, how can I go back from that class to my main application AND pass along data to it (a byte array) ?
As you can see the FileSelector is called with as parameter the main application class (FileSelection)
Inside the FileSelector class the main application class FileSelection is saved as FileSelection fileSelection;

I can't however use display.setCurrent(fileSelection), as I did to get into my class, to get back to my main application.

How can I do this AND pass along my byte array ?

Why cant you use display.setCurrent(fileSelection),Is your main class fileSelection is not a displayable class?
You can try calling any public method of fileSelection class which can take a btye array, for example:

if FileSelection class as a public method processFile(byte[] file){ process and tranfers control to any other required displayable class }, you call it from FileSelector class.

try this

display.setCurrent(object of main class); 

if U dont have object of your main class in fileselector class try passing it to the class and their are other methods but this is the most simplest one for you
