Filling class attribute in background

Hello!

I have a problem with the application class of a bsp. In this class is an attribute which should be filled when the bsp application is started.

The problem is that the filling of this attribute can take much time, so I want to do this in background. This attribute is not critical for the execution of the bsp so that I don't really need it from start up.

My idea is to call a method which fills this attribute, but when the method is called the execution of the bsp is just going on and doesn't wait until the method finished.

Does anybody knows if something like this is possible in the OO Context.
